The 2WHSP catalog of VHE Blazars |
|
Abstract |
High Synchrotron peaked BL Lac objects (HSPs) are a group of blazars characterized by the largest energy peaks, both in the synchrotron and the “inverse Compton” component, this last extending to gamma-ray and VHE. Nevertheless, most of the VHE detected objects are HSPs; however, the number of known HSPs is still relatively small. In this work, we build an HSP catalog (2WHSP) containing over 1500 blazars expected to emit at VHE energies. This catalog includes previously known sources, newly discovery blazars, and candidate blazars. The 2WHSP catalog is an extension of the 1WHSP catalog to the galactic latitude b larger than 10 degrees and smaller than -10 degrees, and uses less stringent color-color requirements in the IR. We cross-matched the multi-wavelength data (Infrared, radio, and X-ray), applied the flux density slope, and examined the SED of each candidate to select genuine HSPs. We compared the relation between the frequency of the synchrotron peak and its flux and the relation between gamma-ray, optical, and radio luminosity densities. |
