Optimized dark matter searches in deep observations of Segue 1 with MAGIC

J. Aleksić, S. Ansoldi, L. A. Antonelli +156

We present the results of stereoscopic observations of the satellite galaxy Segue 1 with the MAGIC Telescopes, carried out between 2011 and 2013. With almost 160 hours of good-qual…

MAGIC upper limits on the GRB 090102 afterglow

MAGIC Collaboration, J. Aleksić, S. Ansoldi +160

Indications of a GeV component in the emission from GRBs are known since the EGRET observations during the 1990's and they have been confirmed by the data of the Fermi satellite. T…

MAGIC observations and multifrequency properties of the Flat Spectrum Radio Quasar 3C 279 in 2011

J. Aleksić, S. Ansoldi, L. A. Antonelli +168

We study the multifrequency emission and spectral properties of the quasar 3C 279. We observed 3C 279 in very high energy (VHE, E>100GeV) gamma rays, with the MAGIC telescopes duri…

Spectroscopy of Optically Selected BL Lac Objects and their gamma-ray emission

A. Sandrinelli, A. Treves, R. Falomo +4

We present Very Large Telescope optical spectroscopy of nine BL Lac objects of unknown redshift belonging to the list of optically selected radio loud BL Lacs candidates. We explor…

Contemporaneous observations of the radio galaxy NGC 1275 from radio to very high energy gamma-rays

MAGIC Collaboration, J. Aleksić, S. Ansoldi +157

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 AGN detected in the VHE regime. In ord…

Rapid and multi-band variability of the TeV-bright active nucleus of the galaxy IC 310

The MAGIC Collaboration, J. Aleksić, L. A. Antonelli +161

Context. The radio galaxy IC 310 has recently been identified as a gamma-ray emitter based on observations at GeV energies with Fermi-LAT and at very high energies (VHE, E>100GeV)…
