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. Astrophysics and space science research efforts at JPL primarily study the physics and origins of our galaxy, and ultimately the universe. Through a developing link with the CLRC's Rutherford Appleton Laboratory (also involved in the FMOS project) we are also contributing to the design and construction of a new 4-m. class survey telescope (VISTA) which will be sited close to the VLT in Chile in 2006. To tackle this problem we need both a physical model for the evolution of quasars, radio sources and active galaxies, and also we need new observational information. The modelling involves both analytical and numerical work, with modern theories of non-linear dynamics playing a unifying role. 0. G Dalton, R Davies, I Hook, I Lewis, P Roche, M Tecza, N Thatte. That work used the purpose built SAURON spectrograph on the William Herschel Telescope with which we are pursuing an extensive survey. A focus of our research includes the study of galaxy formation and evolution. Chrisantus Oden-November 5, 2020. We plan to use IFS on the 8m Gemini and VLT telescopes to extend this work to higher redshift galaxies and into the infrared allowing us to "age" and "weigh" distant galaxies to test the assembly paradigm directly. Q&A: Holly Jackson on building a cosmic family tree. 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. This shows that the stars in both components are the same age. We have also won a Marie Curie Excellence Grant from the European Commission for realising SWIFT, a novel integral field spectrograph. Synthesis of whole spectral regions with inclusion of all likely spectral features is now a viable method of approach. Experimental astrophysics research at MIT spans a huge range in scales, from black holes and planets to the largest structures in the universe. Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. There are two fundamentally different types of supernovae: thermonuclear explosions which occur when a white dwarf is pushed above its maximum mass of 1.4 solar masses (the Chandrasekhar limit) and which leads to the complete disruption of the star (referred to as a 'Type Ia supernova'), and core-collapse supernovae which take place when the core of a massive star has exhausted all of its nuclear fuel. We know that the galaxy population in dense regions of the universe is quite different from that in regions of average density but we do not know why. In theoretical astrophysics, there are strong programmes in the area of galaxy dynamics, cosmology, galaxy formation, dark matter and the cosmic microwave background radiation. 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. The mechanism for transporting gas from ~100 pc scales to the immediate vicinity of the black hole is not well understood, although bars and Linblad resonances do play a vital role. Simulations of sky maps will be one of the activities that will be undertaken at Oxford. We are in the process of constructing a deep wide-field optical and infra-red survey of faint galaxies. 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. The origin of large-scale structure may be probed by studying trace fluctuations in the cosmic microwave background. Yet it is unclear as to what physical processes collude to link two quantities whose size scales differ by a factor of more than a million. Recent observations of the space velocities of pulsars (rapidly rotating neutron stars) have shown that when neutron stars are born in a supernova they receive very large kicks (presumably due to an asymmetry in the supernova explosion). Both sub-departments are situated close to each other on the Keble Road site, close to the centre of Oxford and the University Parks. These are imprinted by primordial irregularities in density that grew by gravitational instability in the early Universe. principles. 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. 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). We are also using the new generation of high-frequency radio surveys to identify sources whose radio jets have very recently been triggered. Undergraduate in electrical engineering and computer science contributes to startling new astronomy research. 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. This will be fed by a robotic fibre-optic positioning system at the prime focus of Japan's 8.3m Subaru telescope. While most stars have solar abundances or are metal-deficient with respect to the Sun, more pronounced abundance anomalies are also found. Astrophysics and space science. At present, a feasibility study is being carried out. We study these objects across the electromagnetic spectrum using the largest ground-based optical and radio telescopes, and space-based facilities such as the HST, Chandra and XMM satellites, as well as infra-red and sub-mm imaging. Super-massive black holes (with masses from a few million to a few billion solar masses) are thought to lurk in the nuclei of all present day galaxies. 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. In the Media. 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. in the Science Center, Room 309A (check for changes!). We are the principal UK partners with Japan in the construction of a wide-field, multi-object, infrared spectrograph project (FMOS). 100 Technology Paper Topics for Research Papers. 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. The experimental cosmology group designs, builds and then uses new instruments for studying the evolution and structure of the Universe. 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. Dissertation topic in Physics relates the research to the independent area of interest like lab techniques, mathematical applications into physics, modern physics, quantum physics, material science, and pivotal discoveries of the universe. Understanding the detailed nature of such signatures will help define a goal for new generations of experiments and satellite missions. Two of the major areas of stellar research involve the study of the late evolution of stars leading to supernova explosions and the modelling of binaries, in particular those containing compact objects. Our work on these problems involves N-body simulation as well as more analytical approaches. 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. 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. 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. Topics: Astrophysics. 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. Submit an article opens in new tab Current research in observational astrophysics and cosmology at Stanford covers a wide range of approaches to tackling the most important frontiers. Download RSS feed: News Articles / In the Media. So far the dynamical implications for our galaxy are not well understood, and Binney has been in the forefront of the struggle to understand these data using models developed both for the dark halo and the Bulge. 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. In the latter case, the core of the star collapses to leave a compact remnant, a neutron star or in some cases a black hole. Physics Project Topics and Research Materials. It is very likely that the decoupled kinematics arose from a merger but character of the stars tells us this happened 12-14 Gyrs ago in the initial star forming event and that the galaxy has been quiescent since. The subject matter of physics includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms. 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. 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. Astrophysics Research Paper Topics. stars and the interstellar medium and a third to galaxies and cosmology. Having used Sauron or a similar instrument to obtain a kinematical map of a galaxy, what does the map tell us about the galaxy's mass distribution? There are good opportunities for graduate students studying for t… Through statistical studies of galaxies in different environments over a range of redshift we can eliminate candidate mechanisms. Our main areas of involvement in the study are in setting the scientific requirements for an ELT and studying potential ELT instruments. A few galaxies have core regions with stellar kinematics that are completely decoupled from those of the rest of the galaxy and this is taken as an indication of a past merger, but when did it occur? J F Wheater* Conformal symmetries and their extensions are a powerful tool in the study of field theories. Savilian Professor of Astronomy: Professor Joe Silk Philip Wetton Professor of Astrophysics & Head of Astrophysics: Professor Roger Davies Professor Steve Rawlings Research at Oxford spans a wide range of astronomy and astrophysics, from the largest scales in the Universe to observational work on stars and the interstellar medium. 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. Active galactic nuclei are thought to be powered by massive black holes.

Integral field and long slit data at near infrared wavelengths, where dust extinction is less significant, are being used to probe the nuclei of spiral galaxies, thus complementing present work that has concentrated on early-type galaxies. 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. KMOS is expected to be operational in 2009. One of the more striking results to have come out of these and other models is that most reasonably large galaxies harbour so-called `supermassive' black holes at their centres. An improved understanding of protogalaxy evolution will have profound implications for understanding chemical evolution and for interpreting far infrared and submillimetre observations of star- forming galaxies in the distant Universe. But due to excessively busy schedule of graduates it is not possible for them to manage topic and work on them as well. Physics Research Paper Topics . By conducting high resolution observations using adaptive optics at near infrared wavelengths, Oxford researchers are studying the close-in nuclear environment of active galaxies. aimed at introducing students to observing and the reduction of Apart from modelling individual systems, we use binary populations synthesis techniques to model the population of X-ray binaries (with US collaborators) and keep active collaborations with observational groups to test our predictions and improve our modelling efforts. These cool physics topics will give you just the calm you need for that research paper, presentation, or exam. J Bell-Burnell, S Justham, A Lynas-Gray, J Miller, P Podsiadlowski.
