Constraints on the very high energy emission from bl lacertae objects
(IOP Publishing, 2004-03-01)
We present results from observations of 29 BL Lacertae objects, taken with the Whipple Observatory 10 m gamma-ray telescope between 1995 and 2000. The observed objects are mostly at low redshift (z<0.2), but observations ...
Discovery of high-energy and very high energy γ-ray emission from the blazar rbs 0413
(IOP Publishing, 2012-04-18)
We report on the discovery of high-energy (HE; E &gt; 0.1 GeV) and very high energy (VHE; E &gt; 100 GeV) gamma-ray emission from the high-frequency-peaked BL Lac object RBS 0413. VERITAS, a ground-based gamma-ray ...
