Next: Arunav Kundu Up: STScI Science Jamboree Previous: Anuradha Koratkar . At the moment most of my time is spent studying the host galaxies of powerful AGN - quasars and radio galaxies - to try to find out how the properties of the host affect those of the active nucleus (and vice versa), and also how galaxy evolution is related to that of the AGN population. ... In pursuit of this I also do a lot of work on Seyfert galaxies and RQQs with the VLA and other radio telescopes. ... 3/24/1998 ...

... A universal physical relation for quasars . ... Harvey Tananbaum and his collaborators have first observed a relation between the soft X-ray and the optical/ultraviolet emission in AGN in 1979. Such relation is nonlinear, and it is usually parameterized as dependence between the logarithm of the monochromatic luminosities at 2500 †Е ( L 2500†Е ) and 2 keV ( L 2keV ) . ... Yet, the dispersion along the L 2500†Е тАУ L 2keV relationship is found to be rather high, typically ~0.35тАУ0.4 in log units. ...
