astrophysics topics for research

New instruments on the Gemini 8-m telescopes allow us to investigate these dusty circumnuclear regions at high spatial resolution for the first time. These have yielded high-redshift radio galaxies whose host-galaxy light should be less affected by the active nucleus, and whose properties give direct information on the formation and early evolution of elliptical galaxies. Much of the focus at Oxford, however, has been on developing a more powerful scheme that makes use of the fact that, when viewed in action-angle co-ordinates, stellar motions are particularly simple, with the stars moving on three-dimensional tori. Oxford Astrophysics has been successful in attracting long-term Royal Society, PPARC Advanced and other Senior Research Fellows funded by a grant from the Leverhulme Trust. These cool physics topics will give you just the calm you need for that research paper, presentation, or exam. Detailed abundance studies of stars in external galaxies (beyond the Magellanic Clouds) are becoming feasible using the HST and 10 metre class ground-based facilities. Physics Project Topics and Research Materials. aimed at introducing students to observing and the reduction of Oxford astrophysicists are very successful in gaining observing time on observing facilities, including 8m class telescopes (Gemini, Subaru, and VLT) and the Hubble Space Telescope for optical and infrared observations, as well as facilities spanning the electromagnetic spectrum from X-ray (XMM-Newton), far-infrared (Spitzer), sub-millimetre (JCMT) through to radio (VLA) wavelengths. See our list of physics research paper topics.Physics is the science that deals with matter and energy and with the interaction between them. As we probe the galaxy distribution to fainter magnitude limits, the study of galaxy clustering is affected by the evolutionary histories of the galaxies themselves, as we see more distant objects at earlier times. Some hypernovae are observationally known to be related to gamma-ray bursts, the most violent and most energetic events known in the Universe. This is an important problem which we are actively studying at the moment, developing both the theoretical framework and the numerical tools to tackle this problem. One of the major uncertainties is that of foregrounds, both galactic and extragalactic, which need to be evaluated in order to enhance the precision of such measurements. The DIRBE instrument that flew on the COBE satellite provided the most detailed picture to date of the Galactic Bulge. Without further ado, let’s delve into the physics topics list prepared specially for you! Following the exciting discovery of low-amplitude pulsation in seventeen sdB stars, the techniques of asteroseismology are being used to constrain stellar evolution models through a determination of envelope structure. In the study of gravitational lenses, the program's main efforts are to discover new lens systems and to use known systems to extract information of astrophysical interest. Recently we have been looking at the details of the spectra of distant supernovae and comparing them with their nearby counterparts, in order to search for possible signs of evolution in the population. While most stars have solar abundances or are metal-deficient with respect to the Sun, more pronounced abundance anomalies are also found. at 9:15:00 AM. It is a fast track project, to be realised over a four year timescale. Key to our understanding are the links between host galaxy type, mass and environment, nuclear activity and starburst activity. There are good opportunities for graduate students studying for the D.Phil research degree (equivalent to Ph.D.). We are particularly interested in so-called low-mass X-ray binaries (LMXB), where a low-mass star with the mass of the Sun or less transfers matter to a neutron star, which as a result becomes a luminous X-ray source. Type Ia supernova SN 1994D in the galaxy NGC 4526, observed by the HST. Rougly speaking a thurd of the course will be devoted to fundamentals, a third to stars and the interstellar medium and a … The present paradigm for galaxy formation and evolution has galaxies assembling in their dark matter halos as these merge to form ever more massive objects over cosmic time. As a student, you’ll be have to write a research … The formation of planets around pulsars (indeed, the first planets outside the solar system were discovered around pulsars) is a related problem of much current interest. Submit an article opens in new tab Quantum gravity is studied in two dimensions where it has many equivalent descriptions including, as a conformal field theory and in high… Philip Wetton Professor of Astrophysics & Head of Astrophysics: Professor Roger Davies A dedicated team of five researchers has already begun working on the project. Displaying 1 - 15 of 204 news articles related to this topic. Astrophysics research is carried out in two sub-departments of physics: Astrophysics and Theoretical physics. astrophysics preprint server and related to the topic of the lectures. SWIFT will provide integral field capability covering the wavelength range 0.7 to 1.0 micron. To do this involves collecting an unprecendented sample of high-redshift supernova with better quality photometric and spectroscopic data. This question is surprisingly difficult to answer, even for the simplest case of a perfectly spherical galaxy. NGC4365, shown in the figure, is a good example. In the area of compact binary evolution, we are particularly interested in studying the evolution of low- and intermediate-mass X-ray binaries and their relation ot millisecond pulsars, and binaries containing black holes and their possible relation to ultraluminous X-ray sources in external galaxies. By using multiple object spectroscopy at both optical and infrared wavelengths we can assemble large galaxy samples for this work. FMOS will see first-light in early 2005, and provides an excellent opportunity for a D.Phil student to become involved in the laboratory testing and science verification phase of the instrument which will address a wide range of science programmes from brown-dwarf stars to the evolution of galaxies at high redshifts. A recently published better understanding of sdB star evolution should help determine the contribution of sdB stars to the observed ultraviolet upturn in giant elliptical galaxies, with the view to its calibration as an age indicator. Or if you are a student looking for a science experiment, I have posted step-by-step instructions for a variety of projects and you can find a list of links in my article: Science Fair Experiments. J F Wheater* Conformal symmetries and their extensions are a powerful tool in the study of field theories. Local galaxies can be studied with greater precision and linear resolution than high redshift galaxies allowing us to make connections between their structure, dynamics and star-formation history. Rougly speaking Predictions of inflationary cosmology, such as the origin and spectrum of density fluctuations and the distribution and composition of dark matter, are important to the understanding of galaxy formation and sensitively depend on the details of the correct particle theory. ADS abstract service, Recombination Coefficients for Hydrogenic Atoms, Distance Measures In Cosmology (PDF) by David Hogg, from astro-ph/9905116, Images of Orion taken by Michelle and Peter, Data table of brightest local group galaxies, The Philosophy of Astrophysics (and this Course! The Oxford workers are engaged in a long term project towards a comprehensive understanding of the Milky Way. KMOS is expected to be operational in 2009. Over the last decade, Binney and co-workers have been developing a new method (the Oxford Torus Project) to analyse the stellar kinematics of nearby stars. It has been recognised for 30 years that the space density of quasars was much higher in the past than at the present day. As a result of a complete merger, the neutron star sinks to the centre of the massive star forming a new hybrid object, generally referred to as a Thorne-Zytkow object (TZO). The website forms part of the Physics World portfolio , a collection of online, digital and print information services for the global scientific community. Astrophysics is a science that employs the methods and principles of physics in the study of astronomical objects and phenomena. Logarithmic conformal field theories have been a major activity for many years; at present we are working on the properties of these theories in the presence of boundaries. In a complementary attack on large-scale structure, the deep galaxy redshift surveys now underway and which will obtain of order a million redshifts have the sensitivity to probe large-scale power in density fluctuations in the nearby Universe. SWIFT's novelty stems from the combination of a very high throughput image slicer based integral field unit, a CCD detector with very high sensitivity at red wavelengths, and the enhanced sensitivity and resolution afforded by an adaptive optics system. One of the most important recent discoveries in this field, which indeed may challenge the above paradigm for LMXBs, is the realization that many stars in so-called Òlow-massÓ X-ray binaries originate from much more massive progenitors (e.g., Cyg X-2, Cyg X-3). We are also involved in a large consortium that will carry out a feasibility study for WFMOS, the most challenging of the Gemini second generation instruments. New ground-based infrared and submillimetre observations are shedding new light on this problem, together with Hubble Space Telescope infrared imaging of quasar host galaxies. While supernova kicks are important for understanding the formation of LMXBs in the Galactic disc, in dense stellar environments like globular clusters, other processes may be more important. Hypernovae are a rare, new supernova type, first identified in 1998, which are much more energetic than a normal supernova and are probably caused by the collapse of a rapidly rotating helium star to a stellar-mass black hole. Oxford was the coordinating node for CMBNET, a European network for collaborative research into the cosmic microwave background, and for the Early Universe European network for particle cosmology. Q&A: Holly Jackson on building a cosmic family tree. Theory provides predictions of the spectrum of fluctuations in the matter distribution of the Universe, but testing these predictions by making observations is by no means straightforward. We are the principal UK partners with Japan in the construction of a wide-field, multi-object, infrared spectrograph project (FMOS). We are involved in the definition of the science case for such a telescope, with particular focus on the larger end of the range, from 50-100m (this work is supported by the European network OPTICON) Oxford is also involved in a major European technical design study for an ELT. We aim to disentangle the effects of the radio activity, and the active nuclei which power them, from the underlying starlight. If most stars evolve through the sdB star stage, following evolution up the giant branch, understanding the envelope loss which results in sdB star formation is crucial to understanding the late stages of stellar evolution; it would also be the key to understanding chemical evolution of a galaxy or star cluster over several stellar generations. In addition to using normal and active galaxies as cosmological probes, there are a number of programmes at Oxford which aim to improve our understanding of how active galaxies work. However, whether this is a viable process depends on the response of the normal star when the tidal energy is deposited inside the star (the tidal energy can be a large fraction of the binding energy of the star). That is why Students Assignment Help experts have suggested free topics for physics to the students here. The various binary interactions (mass loss, mass accretion and merging) can fundamentally change the structure of a massive star and may thereby account for many of the observational supernova sub-classes. Our work seeks to characterise and model local galaxies as a function of luminosity, environment and Hubble type. Astronomy Now: This is the site for the magazine Astronomy Now and has articles on all kinds of stuff that has to do with astronomy. Semi-analytical techniques can be applied to yield global star formation rates in disk galaxies and evolve nearby galaxies backwards in time. 0. Writing Physics assignment like research papers, essays, term papers and thesis always require students to have good quality topics. Physics World represents a key part of IOP Publishing's mission to communicate world-class research and innovation to the widest possible audience. When the Universe was about one-third of its present age there were about 100 times more quasars of a given luminosity than there are today, after allowing for the expansion of the Universe since that time. Problem sets and their solutions will be posted on this website during the We use the luminosity in X-rays to signal the presence of a true physical association at high redshift and to determine the local density of the intergalactic medium. Astrophysics Research Current Missions. These programmes require observations at all wavebands, and often at the high angular resolution offered by Very Long Baseline Interferometry at radio wavelengths or the HST in the infrared, optical and ultraviolet wavebands. Research topics include nonlinear optical techniques for the study of higher orders of light-matter interaction that enable the coupling of electronic and photonics and the control of light with light, and the development of new organic materials for photonics and optoelectronics applications such as all-optical switching and electro-optic modulators (Biaggio). We are now involved in designing, fabricating and deploying second generation instruments at three different 8-meter class telescopes - the European Southern Observatory's Very Large Telescope (VLT), the Gemini telescopes and the Japanese Subaru telescope. Perhaps the most important development has been that of the inflationary cosmology, which may solve a number of outstanding problems that have puzzled cosmologists for over half a century. At face value, the results suggest an accelerating Universe, a dramatic break from the previous picture. Browse Astrophysics news, research and analysis from The Conversation Astrophysics – News, Research and Analysis – The Conversation – page 1 Menu Close Active galactic nuclei are thought to be powered by massive black holes. KMOS will be equipped with deployable mini integral field units, thus providing spatially resolved information of over two dozen targets within a 7 arcminute diameter field. Work is now underway to understand the nature of the mysterious "Dark Energy" driving this acceleration. We are also determining how the entropy injected into the intergalactic medium by jets influences galaxy formation and evolution. of Durham, UKATC) we have won a competitive bid to design and construct KMOS, the cryogenic, multi-object, near-infrared spectrometer for the ESO VLT. This will be used to identify candidate clusters of galaxies at a range of cosmological epochs, which will be followed up using the new generation of 8-m. telescopes to study the evolution of galaxies and galaxy clustering. GMOS galaxy image, Ivan Delvecchio – The infrared-radio correlation of star-forming galaxies (TBC), Clarendon Laboratory Like quasars and other active galaxies, luminous radio sources are also concentrated in the younger Universe. Download RSS feed: News Articles / In the Media. mid-term exam. However, star formation can sometimes play a major role in the energetics of the nuclear region. WFMOS will provide simultaneous spectra of ~5000 galaxies spread over a 1.5 degree field of view, in order to answer fundamental questions about the complexity of the Universe and to determine the equation of state of dark energy. Understanding how galaxies form and unravelling the nature of the origin of the large-scale structure of the Universe are key unresolved issues in cosmology. Again our main interest is in understanding what type of stellar system can produce the progenitors of these spectacular events. G Dalton, R Davies, I Hook, I Lewis, P Roche, M Tecza, N Thatte. We have also won a Marie Curie Excellence Grant from the European Commission for realising SWIFT, a novel integral field spectrograph. J Binney*, S Kay, S Khochfar, J Magorrian*, P Ferreira, J Silk. We are also involved in a joint OPTICON-PPARC effort to define and develop science programs for the next generation of 30 and 100 meter telescopes (ELTs). The aim of this research is to study the formation and evolution of galaxies and their large-scale distribution. Our group is working on a number of surveys of large-scale structure as traced by galaxies and clusters of galaxies, both nearby and distant. Over the last decade the Oxford Torus Project has been developing the tools necessary to apply these ideas to the construction of detailed models of real galaxies. Astrophysics and space science. Astrophysics: Interdisciplinary views of … Subdwarf-B (sdB) star research is of interest to investigations of stellar mass-loss, as these stars appear to represent extreme cases of near complete envelope loss during the later stages of stellar evolution. However, statistical comparisons between millisecond pulsars and LMXBs suggest that there are either too many millisecond pulsars relative to the number of LMXBs or that the duration of the LMXB phase has been overestimated by a large factor. We will then cover a broad but selected set of topics that will range accross stellar evolution, star formation, the interstellar medium, cosmology and extragalctic astronomy.
