The fast UV variability of the active galactic nucleus in Fairall 9
Anne Lohfink, Christopher Reynolds, Ranjan Vasudevan +2
We present results from a new optical/UV/X-ray monitoring campaign of the luminous Seyfert galaxy Fairall 9 using the Swift satellite. Using the UV-Optical Telescope (UVOT) on Swif…
The power output of local obscured and unobscured AGN: crossing the absorption barrier with Swift/BAT and IRAS
R. V. Vasudevan, A. C. Fabian, P. Gandhi +2
The Swift/BAT 9-month catalogue of active galactic nuclei (AGN) provides an unbiased census of local supermassive black hole accretion, and probes to all but the highest levels of…
Radiation pressure and absorption in AGN: results from a complete unbiased sample from Swift
A. C. Fabian, R. V. Vasudevan, R. F. Mushotzky +1
Outward radiation pressure can exceed the inward gravitational pull on gas clouds in the neighbourhood of a luminous Active Galactic Nucleus (AGN). This creates a forbidden region…
