The radio galaxy NGC 1275, recently identified as a very high energy (VHE, > 100 GeV) gamma-ray emitter by MAGIC, is one of the few non-blazar active galactic nuclei detected in the VHE regime. The purpose of this work is to better underst[...]texto impreso

The Crab pulsar is the only astronomical pulsed source detected at very high energy (VHE, E > 100 GeV) gamma rays. The emission mechanism of VHE pulsation is not yet fully understood, although several theoretical models have been propo[...]texto impreso

The pulsar wind nebula (PWN) 3C 58 is one of the historical very high-energy (VHE; E > 100 GeV) ?-ray source candidates. It is energized by one of the highest spin-down power pulsars known (5% of Crab pulsar) and it has been compared wi[...]texto impreso

We observed the BL Lac object 1ES 1727+502 in stereoscopic mode with th[...]texto impreso
Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; Miranda Pantoja, José Miguel ; Scapin, Valeria | EDP Sciencies | 2012-03We 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 [...]texto impreso
