Two new catalogs of blazar candidates in the WISE Infrared sky. (2019)

Keywords : BL Lacertae objects general - catalogs - galaxies: active - radiation mechanisms: non-thermal

Abstract:We present two catalogs of radio-loud candidate blazars whose Wide-Field Infrared Survey Explorer (WISE) mid-infrared colors are selected to be consistent with the colors of confirmed {gamma}-ray-emitting blazars. The first catalog is the improved and expanded release of the WISE Blazar-like Radio-Loud Sources (WIBRaLS) catalog presented by D'Abrusco et al. It includes sources detected in all four WISE filters, spatially cross-matched with radio sources in one of three radio surveys and radio-loud based on their q_22_ spectral parameter. WIBRaLS2 includes 9541 sources classified as BL Lacs, flat-spectrum radio quasars, or mixed candidates based on their WISE colors. The second catalog, called KDEBLLACS, based on a new ...(more)

we present two new catalogs of blazar candidates, selected on the basis of their WISE mid-IR colors, association with a radio counterpart, and radio-loudness. These new catalogs contain a combined total of 15196 candidate blazars, including both candidate FSRQs and BL Lacs, distributed on ~90% of the sky.
