Discovery of VHE γ-ray emission from the BL Lacertae object B3 2247+381 with the MAGIC telescopes

Aims: We study the non-thermal jet emission of the BL Lac object B3 2247+381 during a high optical state. Methods: The MAGIC telescopes observed the source during 13 nights between September 30th and October 30th 2010, collecting a total of 14.2 h of good quality very high energy (VHE) γ-ray data. S...

Methods: The MAGIC telescopes observed the source during 13 nights between September 30th and October 30th 2010, collecting a total of 14.2 h of good quality very high energy (VHE) γ-ray data.

We also use high energy γ-ray (HE, 0.1-100 GeV) data from the Fermi satellite. Results: The BL Lac object B3 2247+381 (z = 0.119) was detected, for the first time, at VHE γ-rays at a statistical significance of 5.6σ. A soft VHE spectrum with a photon index of -3.2 ± 0.6 was determined. No significant short term flux variations were found.
