Sažetak:
The MAGIC collaboration reports the detection of very high energy (VHE) gamma-ray emission from 1ES 2037+521 (RA 20h39m23.5s, DEC +52d19m50s, J2000.0). The object was observed with the MAGIC telescopes for 11 hours between 2016/09/26 and 2016/09/30. The preliminary analysis of these data resulted in the detection of 1ES 2037+521 with a statistical significance of 5.7 standard deviations. The preliminary VHE flux from these observations was estimated to be about about 6e-12 cm-2 s-1 above 200 GeV, which is about 3% of the flux from the Crab nebula. 1ES 2037+521 is located at redshift 0.053 (Sbarufatti et al., 2006) and classified as a BL Lac candidate in Veron-Cetti & Veron, 2006. Its X-ray and gamma-ray spectra is hard, which suggest this source may be an extreme HBL (Costamante et al. 2001). MAGIC observations on 1ES 2037+521 will continue until October 3rd, and multiwavelength observations are encouraged. The MAGIC contact persons for these observations are R. Mirzoyan (Razmik.Mirzoyan@mpp.mpg.de) and V. Fallah Ramazani (vafara@utu.fi). MAGIC is a system of two 17m-diameter Imaging Atmospheric Cherenkov Telescopes located at the Canary island of La Palma, Spain, and designed to perform gamma-ray astronomy in the energy range from 50 GeV to greater than 50 TeV.
