Discovery of High-Energy Gamma-Ray Emission from the BL Lac Object RBS 0413
Abstract
The VERITAS and Fermi-LAT Collaborations report the discovery of gamma-ray emission from the high-frequency-peaked BL Lac object RBS 0413 (RA: 03h19m51.8s, Dec: +18d45m34s). The redshift of this blazar is 0.19 (Stocke, J. et al. 1991, ApJS, 76, 813). Very-high-energy (VHE; >100 GeV) gamma rays were detected in ~16 hours of good-quality observations obtained between 23 September 2008 and 26 October 2009 with the VERITAS atmospheric- Cherenkov telescope array.
