Indirect dark matter searches in the dwarf satellite galaxy Ursa Major II with the MAGIC Telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +142
The dwarf spheroidal galaxy Ursa Major II (UMaII) is believed to be one of the most dark-matter dominated systems among the Milky Way satellites and represents a suitable target fo…
Constraining Lorentz invariance violation using the Crab Pulsar emission observed up to TeV energies by MAGIC
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +142
Spontaneous breaking of Lorentz symmetry at energies on the order of the Planck energy or lower is predicted by many quantum gravity theories, implying non-trivial dispersion relat…
Performance of the MAGIC telescopes under moonlight
D. Guberman, P. Colin
MAGIC, a system of two imaging atmospheric Cherenkov telescopes, achieves its best performance under dark conditions, i.e. in absence of moonlight or twilight. Since operating the…
Search for very-high-energy gamma-ray emission from the microquasar Cygnus X-1 with the MAGIC telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +144
The microquasar Cygnus X-1 displays the two typical soft and hard X-ray states of a black-hole transient. During the latter, Cygnus X-1 shows a one-sided relativistic radio-jet. Re…
MAGIC observations of the microquasar V404 Cygni during the 2015 outburst
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +142
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. Becaus…
Observation of the Black Widow B1957+20 millisecond pulsar binary system with the MAGIC telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +145
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 w…
Performance of the MAGIC telescopes under moonlight
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +143
MAGIC, a system of two imaging atmospheric Cherenkov telescopes, achieves its best performance under dark conditions, i.e. in absence of moonlight or twilight. Since operating the…
First Multi-wavelength Campaign on the Gamma-ray-loud Active Galaxy IC 310
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +160
The extragalactic VHE gamma-ray sky is rich in blazars. These are jetted active galactic nuclei viewed at a small angle to the line-of-sight. Only a handful of objects viewed at a…
MAGIC detection of very high energy gamma-ray emission from the low-luminosity blazar 1ES 1741+196
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +159
We present the first detection of the nearby (z=0.084) low-luminosity BL Lac object 1ES 1741+196 in the very high energy (VHE: E100 GeV) band. This object lies in a triplet of i…
A luminous and isolated gamma-ray flare from the blazar B2 1215+30
VERITAS Collaboration, A. U. Abeysekara, S. Archambault +84
B2 1215+30 is a BL Lac-type blazar that was first detected at TeV energies by the MAGIC atmospheric Cherenkov telescopes, and subsequently confirmed by the VERITAS observatory with…
