A sample of Swift/SDSS faint blazars |
|
Abstract |
Abstract: We present a new sample of faint blazars (radio flux above 1 mJy) serendipitously discovered in deep Swift images centered around 140 Gamma-ray bursts (GRBs). Due to the stacking of the images we obtain exposures ranging from ten thousnd to one million seconds. Since GRBs are randomly distributed across the sky our set of deep fields can be considered an unbiased survey of approximately 12 squares degrees of extragalactic sky reaching very low sensitivities. Restricting ourselves to regions where data from SDSS DR12 is available, we find 298 potential sources. Using this sample we derive general statistical properties and build their X-ray LogN-LogS. |
