Multi-wavelength characterization of the blazar S5 0716+714 during an unprecedented outburst phase
Context. 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 observations were triggered by the ...
Periastron Observations of TeV Gamma-Ray Emission from a Binary System with a 50-year Period
We report on observations of the pulsar/Be star binary system PSR J2032+4127/MT91 213 in the energy range between 100 GeV and 20 TeV with the Very Energetic Radiation Imaging Telescope Array and Major Atmospheric Gamma ...
Quasi-periodicities of BL Lacertae objects
We review the reports of possible year-long quasi-periodicities of BL Lac objects in the gamma-ray and optical bands, and present a homogeneous time analysis of the light curves of PKS2155-304, PG1553+113, and BL Lac. Based ...
MAGIC observations of the microquasar V404 Cygni during the 2015 outburst
The microquasar V404 Cygni underwent a series of outbursts in 2015, June 15-31, during which its flux in hard X-rays (20-40 keV) reached about 40 times the Crab nebula flux. Because of the exceptional interest of the flaring ...
MAGIC detection of very high energy gamma-ray emission from the low-luminosity blazar 1ES 1741+196
We present the first detection of the nearby (z = 0.084) low-luminosity BL Lac object 1ES 1741+196 in the very high energy (E > 100 GeV) band. This object lies in a triplet of interacting galaxies. Early predictions had ...
Multifrequency studies of the peculiar quasar 4C+21.35 during the 2010 flaring activity
<p>
The discovery of rapidly variable Very High Energy ( VHE; E > 100 GeV). - ray emission from 4C + 21.35 ( PKS 1222+ 216) by MAGIC on 2010 June 17, triggered by the high activity detected by the Fermi Large Area ...
Multiwavelength observations of a VHE gamma-ray flare from PKS 1510-089 in 2015
Context. PKS 1510 089 is one of only a few flat spectrum radio quasars detected in the very-high-energy (VHE, > 100 GeV) gamma-ray band.Aims. We study the broadband spectral and temporal properties of the PKS 1510 089 ...
Observation of the black widow B1957+20 millisecond pulsar binary system with the MAGIC telescopes
B1957+20 is a millisecond pulsar located in a black-widow-type compact binary system with a low-mass stellar companion. The interaction of the pulsar wind with the companion star wind and/or the interstellar plasma is ...
Observations of Sagittarius A* during the pericenter passage of the G2 object with MAGIC
Context. We present the results of a multi-year monitoring campaign of the Galactic center (GC) with the MAGIC telescopes. These observations were primarily motivated by reports that a putative gas cloud (G2) would be ...
Unraveling the Complex Behavior of Mrk 421 with Simultaneous X-Ray and VHE Observations during an Extreme Flaring Activity in 2013 April*
We report on a multiband variability and correlation study of the TeV blazar Mrk 421 during an exceptional flaring activity observed from 2013 April 11 to 19. The study uses, among others, data from GLAST-AGILE Support ...
