Illuminating Radio Dim/Gamma-ray Bright Active Galactic Nuclei
Abstract
A recent survey of high-latitude gamma-ray sources by Schinzel et al. (arXiv:1702.070336), reveals a sample of about 100 objects which are not detected in the 4-10 GHz radio band to a limiting flux of about 2mJy. This apparent lack of radio flux is puzzling, and may indicate either an extreme Compton-dominated sample, or copious gamma-ray emission from a heretofore unknown population such as a subclass of radio-quiet AGN. To further investigate the nature sources, we have undertaken the task of searching for transient or faint steady emission in the ~15-100-keV X-ray band using the Swift/BAT archive. Here we discuss the analysis, detection's (or not) , and any spectral or temporal information that may enable us to assess the nature of these sources.
