Geoff Bicknell, Alexander Wagner We are engaged in the following computationally intensive projects related to Black Hole and other energetic phenomena. Accretion disks. ... We envisage that we will determine the way in which gravitational energy is channeled into the high temperature coronae of black hole accretion disks and into relativistic jets and winds. ... Feedback from black holes and starbursts. ... COALA : Universe Galaxy AGN Star Planet ...
... For us to see them from such great distances, quasars must be producing enormous energy -- they are about 1000 times brighter than an average galaxy! ... One of their choices for the energy source of quasars was a black hole. ... On the one hand, it may seem difficult to think that mere friction between bits of matter could account for the energy of a quasar, but, on the other hand, gravity is unimaginably strong near a black hole. ... How does matter actually rush towards the black hole? ...
HST optical image 0.8 microns . The Experiment: AGN and galaxy evolution . A small fraction of galaxies contain an “Active Nucleus” (AGN) ? probably a supermassive black hole ? gas falls towards BH (accretion) ? ... AGN in some emits two jets of plasma ? ... Immense power of AGN ? do the modify evolution of galaxy . ... High resolution telescopes to probe the working of the AGN . Previous slide . Next slide . Back to first slide . ...

Also in Lyra is the double star Beta Lyrae (Sheliak). This is in fact a close eclipsing pair of B-class stars about 960 light years from the Sun and was only the second eclipsing binary system to be discovered after Algol. ...

The NICMOS team has devised a comprehensive program of observations of the Galactic Center. ... Data in hand give a first look at variability and a detailed look at the search for the tip of the main sequence will be discussed where NICMOS has demonstrated adequate sensitivity and photometric precision to identify likely O8-B1 stars at the Galactic Center. ...
... Previous: Substepping and its Application to HST Imaging . ... This is a preliminary report on an application of the co-addition technique based upon the Richardson-Lucy algorithm. The combination of high signal-to-noise ground-based images obtained with the ESO NTT using SUSI with high angular resolution HST FOC f/96 images gives new insights on the properties of galaxy cores and their potential time variability. Cores of galaxies are one of the main thrusts of present extragalactic research. ...
