Serendipity in Astronomy
A. C. Fabian
Astronomy is an observationally-led subject where chance discoveries play an important role. A whole range of such discoveries is continually made, from the trivial to the highly s…
Imaging an Event Horizon: submm-VLBI of a Super Massive Black Hole
Sheperd Doeleman, Eric Agol, Don Backer +20
A long standing goal in astrophysics is to directly observe the immediate environment of a black hole with angular resolution comparable to the event horizon. Realizing this goal w…
A Compton-thick Wind in the High Luminosity Quasar, PDS 456
J. N. Reeves, P. T. O'Brien, V. Braito +7
PDS 456 is a nearby (z=0.184), luminous (L_bol ~10^47 erg/s) type I quasar. A deep 190 ks Suzaku observation in February 2007 revealed the complex, broad band X-ray spectrum of PDS…
The detection of Broad Iron K and L line emission in the Narrow-Line Seyfert 1 Galaxy 1H0707-495 using XMM-Newton
A. C. Fabian, A. Zoghbi, R. R. Ross +14
Since the discovery of the first broad iron-K line in 1995 from the Seyfert Galaxy MCG--6-30-15, broad iron-K lines have been found in several other Seyfert galaxies, from accretin…
PHL 1092 as a transient extreme X-ray weak quasar
G. Miniutti, A. C. Fabian, W. N. Brandt +2
We report a dramatic variability event in the X-ray history of the Narrow-Line quasar PHL 1092 (z=0.396). Our latest 2008 XMM-Newton observation reveals a flux drop of ~200 with re…
Cosmic Feedback from Supermassive Black Holes
A. Fabian, E. Churazov, M. Donahue +16
An extraordinary recent development in astrophysics was the discovery of the fossil relationship between central black hole mass and the stellar mass of galactic bulges. The physic…
