The Swift/BAT team announces a new website featuring 153 AGN found in
the first 9 months of the BAT all sky survey. Several of the
detections in the 9-month survey are the first high energy detections
of these galaxies, including objects not known to be AGN before
detection in this survey.
The website can be found at http://swift.gsfc.nasa.gov/docs/swift/results/bs9mon/.
The website presents the data from the BAT instrument for the catalog
sources including the hard X-ray flux in 4 bands and the 9-month
lightcurves. The BAT survey is fairly uniform across the entire sky;
the 4.8 sigma threshold in the 9-month survey covers 80% of the sky at
a flux threshold of 3.5x10-11 ergs/cm2/s in the 14-195 keV band and
covers one third of the sky near the ecliptic poles to 2.5x10-11
ergs/cm2/s.
A full description of the survey and the 9-month AGN catalog can be
found in Tueller et al. (arXiv:0711.4130). The full BAT data set is
archived at the HEASARC and available to the public.
