Naslov: MAGIC observes increased VHE gamma ray flux from M87

Sažetak:
The MAGIC collaboration reports the observation of a high flux level in the gamma ray emission from the radio galaxy M87 above 100GeV. The observation was performed in stereoscopic mode using the two 17m diameter telescopes on La Palma, Canary Islands, Spain , during 2.5 hours from MJD 55236.06 to 55236.19 (February 9th 2010). The recorded signal corresponds to an integral flux >10% of the Crab Nebula flux. This level is similar to the flaring activity detected in 2005 by HESS and in February 2008 by MAGIC and VERITAS. The previous very high energy outbursts were contemporaneous to high activity in the core region in X-ray and radio bands. MAGIC will continue to observe M87 and multi-frequency observations are strongly encouraged.
