... Research . ... A rare hybrid morphology radio galaxy . ... In this project we will be able to investigate the environmental effect on star formation and galaxy evolution in individual galaxies falling into the cluster through radio observations of active galactic nuclei (AGN). Current models of galaxy evolution regulate the star formation rates within the simulated galaxies by invoking radio-mode feedback from AGN. ... Julie.Banfield@anu.edu.au . ...
23. Population Synthesis of X-ray Sources at the Galactic Center
Next: The Model Up: No Title Previous: Radiopulsars as Sources of . In this section, we study the evolution of stellar populations on a time-scale of 10 Myr for a starburst occurring under conditions similar to those in the Galactic Center (see Lipunov et al. (1995d)[ 126 ]). We estimate the expected number of X-ray transient sources (NS + MS star), super accreting BH, and BH + supergiant binaries, all as functions of time elapsed after the burst. ...

25. XMM Deep Survey Simulations
... QSO spectra in the ROSAT band are steeper than the background at harder energies, and furthermore at fluxes below 1E-14 ergs/(s cm) the quasar source counts flatten off and are replaced by more numerous populations of relatively low red-shift objects, apparently Narrow Emission Line Galaxies (NELG). ... We extracted the luminosity function from ROSAT Deep Survey results, and extrapolated by a factor of 2 - 3 to account for changes expected in the harder XMM band. ...

27. First X-Rays From a Comet Discovered
A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ...
