... Science Users Information > Science Publications > Science Announcements > Release of VISTA Deep Extragalactic Observations Survey Data in the VIDEO-XMM Field . ... ESO Data . ... The first public data release ( DR1 ) of the VIDEO programme via the ESO Science Archive Facility, contained 97 individual (i.e. single-OB) tile images in the VIDEO-XMM3 field and their associated single-band source lists. This release (VIDEO-XMM DR2) adds 156 single-OB images in the VIDEO-XMM fields 1, 2 and 3. ...

... Firenze . The extragalactic group is involved in several lines of research covering a variety of topics from theory to observations across the electromagnetic spectrum (from gamma-rays to radio): the primordial Universe; the physical and evolutionary properties of high-redshift galaxies; the physical processes of nearby and distant AGN; the properties of nearby and high-z SNe; the gas, dust and dark matter physics in nearby normal galaxies and starbursts. ... 055 27521 Fax 055 220039 ...

The detection by EGRET of 40 active galactic nuclei in high energy gamma rays ahs sparked interest in high energy extragalactic gamma ray astronomy. ... In this thesis I investigate the infrared background, the interactions by which it absorbs gamma rays, and I develop a program that uses monte carlo techniques, as well as suitable approximations to model the effect of these interactions on gamma ray spectra, and discuss the implications for high energy gamma ray astronomy. | ...

... Up: Science Data Pipelines . ... We designed and developed a package which simulates extragalactic point source data within a given field of view and SIRTF band. ... The simulator is modular and extensible to enable multi-wavelength simulations, has been optimized by utilizing parallel processing capabilities, and will be used to test pipeline software. ... The extragalactic simulator is capable of generating large numbers of galaxies within a given patch of sky for SIRTF pipeline testing. ...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... In the late 1970s, jets were discovered in megaparsec-long radio galaxies. ... This involved the first quantitative analysis of jet warping, bending and disruption in galactic halos. ... Hot spots are created where a jet finally crashes into the surrounding medium. ... I extended the so-called Twin Exhaust Model, using numerical simulations to show that hot gas can be ejected in three forms: jets, bubbles and clouds. ...
