J/ApJ/633/L77          SWIFT/BAT detections of AGN            (Markwardt+, 2005)

The Swift/BAT high-latitude survey: first results. Markwardt C.B., Tueller J., Skinner G.K., Gehrels N., Barthelmy S.D., Mushotzky R.F. <Astrophys. J., 633, L77-L80 (2005)> =2005ApJ...633L..77M
ADC_Keywords: Active gal. nuclei ; Gamma rays ; Surveys Keywords: galaxies: active - gamma rays: observations - surveys Abstract: We present preliminary results from the first 3 months of the Swift Burst Alert Telescope (BAT) high Galactic latitude survey in the 14-195keV band. The survey reaches a flux of ∼10-11erg/cm2/s and has ∼2.7' (90% confidence) positional uncertainties for the faintest sources. This represents the most sensitive survey to date in this energy band. These data confirm the conjectures that a high-energy-selected active galactic nucleus (AGN) sample would have very different properties from those selected in other bands and that it represents a "true" sample of the AGN population. We have identified 86% of the 66 high-latitude sources. Twelve are Galactic-type sources, and 44 can be identified with previously known AGNs. File Summary:
