Constraining very-high-energy and optical emission from FRB 121102 with the MAGIC telescopes

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +155

Fast radio bursts (FRBs) are bright flashes observed typically at GHz frequencies with millisecond duration, whose origin is likely extragalactic. Their nature remains mysterious,…

The extreme HBL behaviour of Markarian 501 during 2012

M. L. Ahnen, S. Ansoldi, L. A. Antonelli +276

A multiwavelength campaign was organized to take place between March and July of 2012. Excellent temporal coverage was obtained with more than 25 instruments, including the MAGIC,…

The blazar TXS 0506+056 associated with a high-energy neutrino: insights into extragalactic jets and cosmic ray acceleration

S. Ansoldi, L. A. Antonelli, C. Arcaro +146

A neutrino with energy of 290 TeV, IceCube-170922A, was detected in coincidence with the BL Lac object TXS~0506+056 during enhanced gamma-ray activity, with chance coincidenc…

The broad-band properties of the intermediate synchrotron peaked BL Lac S2 0109+22 from radio to VHE gamma rays

MAGIC Collaboration, S. Ansoldi, L. A. Antonelli +163

The MAGIC telescopes observed S2 0109+22 in 2015 July during its flaring activity in high energy gamma rays observed by Fermi-LAT. We analyse the MAGIC data to characterise the ver…

Multi-wavelength characterization of the blazar S5~0716+714 during an unprecedented outburst phase

MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +187

The BL Lac object S5~0716+714, a highly variable blazar, underwent an impressive outburst in January 2015 (Phase A), followed by minor activity in February (Phase B). The MAGIC obs…

Spectroscopic characterization of the protocluster of galaxies around 7C 1756+6520 at z ~ 1.4

V. Casasola, L. Magrini, F. Combes +6

The aim of this paper is the spectroscopic study of 13 galaxies belonging to the field of the protocluster associated with the radio galaxy (RG) 7C 1756+6520 at z = 1.4156. In part…
