Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nieto, Daniel ; Satalecka, Konstanzja ; Scapin, Valeria | EDP Sciencies | 2012-05Galaxy clusters are being assembled today in the most energetic phase of hierarchical structure formation which manifests itself in powerful shocks that contribute to a substantial energy density of cosmic rays (CRs). Hence, clusters are expecte[...]texto impreso
Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2007-11-10We report on very high energy gamma-ray observations with the MAGIC Telescope of the pulsar PSR B1951+32 and its associated nebula, CTB 80. Our data constrain the cutoff energy of the pulsar to be less than 32 GeV, assuming the pulsed gamma-ray [...]texto impreso
Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2009-11-20The discovery of very high energy (VHE) gamma-ray emitting X-ray binaries has triggered an intense effort to better understand the particle acceleration, absorption, and emission mechanisms in compact binary systems, which provide variable condi[...]texto impreso
Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2010-11-10We report on the detection with the MAGIC telescopes of very high energy (VHE) gamma-rays from IC 310, a head-tail radio galaxy in the Perseus galaxy cluster, observed during the interval 2008 November to 2010 February. The Fermi satellite has a[...]texto impreso

The optical counterpart is the Be star MWC 148, and a compact object of unknown nature orbits it every similar to 321 days with a hi[...]texto impreso
Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2007-08-01We report the detection of a new source of very high energy (VHE; E-gamma > = 100 GeV) gamma- ray emission located close to the Galactic plane, MAGIC J0616 + 225, which is spatially coincident with supernova remnant IC 443. The observations were[...]texto impreso
Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2009-02-10The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 hr in 2007 August-December. The observations resulted in the discovery of a gamma-ray source centered at celestial coordinates R.A. = 2(h)23(m)12(s) and decl.=43 d[...]texto impreso
Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2007-09-20We report on the discovery of very high energy (VHE) gamma-ray emission from the BL Lacertae object 1ES 1011+496. The observation was triggered by an optical outburst in 2007 March and the source was observed with the MAGIC telescope from 2007 M[...]texto impreso

Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2011-08-01We report on the gamma-ray activity of the high-synchrotron-peaked BL Lacertae object Markarian 421 (Mrk 421) during the first 1.5 years of Fermi operation, from 2008 August 5 to 2010 March 12. We find that the Large Area Telescope (LAT) gamma-r[...]texto impreso
Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2008-09-20High-energy gamma-ray emission is theoretically expected to arise in tight binary star systems (with high mass loss and high-velocity winds), although the evidence of this relationship has proven to be elusive so far. Here we present the first b[...]texto impreso
