Abstract:
An accurate census of the active galactic nuclei (AGN) is a key step
in investigating the nature of the correlation between the growth and
evolution of super massive black holes and galaxy evolution. X-ray
surveys provide one of the most efficient ways of selecting AGN.
Description:
The Table contains the SwiftFT catalog of the serendipitous sources
detected in over 370 Swift-XRT fields centered on gamma ray bursts,
which were detected between 2004 and 2008 and observed with total
exposures ranging from 10ks to over 1Ms.
