New hard-TeV extreme blazars detected with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +175
Extreme high-frequency peaked BL Lac objects (EHBLs) are blazars which exhibit extremely energetic synchrotron emission. They also feature non-thermal gamma-ray emission whose peak…
MAGIC observations of Dragonfly Nebula at TeV Energies using the Very Large Zenith Angle Technique
Darko Zarić, Razmik Mirzoyan, Ievgen Vovk +5
One of the brightest regions of diffuse gamma-ray emission in the northern sky is the Cygnus star-forming region, where one can assume the most energetic processes are taking place…
Searching for Variability of the Crab Nebula Flux at TeV Energies using MAGIC Very Large Zenith Angle Observations
Juliane van Scherpenberg, Razmik Mirzoyan, Ievgen Vovk +5
The Crab nebula was once considered to be a stable source until strong flares, up to 30 times increase in flux, were observed in the MeV and GeV energy range by the AGILE and Fermi…
Novel Back-coated Glass Mirrors for the MAGIC Telescopes
Martin Will, Juliane van Scherpenberg, Razmik Mirzoyan +1
The mirrors installed on Imaging Atmospheric Cherenkov Telescopes like the MAGIC telescopes in La Palma, Canary Islands, are constantly exposed to the harsh environment. They have…
The Crab Nebula Spectrum at ~100 TeV Measured with MAGIC under Very Large Zenith Angles
Michele Peresano, Razmik Mirzoyan, Ievgen Vovk +5
The Crab Nebula was discovered as the first very-high-energy gamma-ray source by the Whipple Observatory in 1989. Thirty years after its discovery it is still the reference source…
Testing emission models on the extreme blazar 2WHSP J073326.7+515354 detected at very high energies with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +173
Extreme high-energy peaked BL Lac objects (EHBLs) are an emerging class of blazars. Their typical two-hump structured spectral energy distribution (SED) peaks at higher energies wi…
Constraints on gamma-ray and neutrino emission from NGC 1068 with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +172
Starburst galaxies and star-forming active galactic nuclei (AGN) are among the candidate sources thought to contribute appreciably to the extragalactic gamma-ray and neutrino backg…
Measurement of the Extragalactic Background Light using MAGIC and Fermi-LAT gamma-ray observations of blazars up to z = 1
MAGIC collaboration, V. A. Acciari, S. Ansoldi +157
We present a measurement of the extragalactic background light (EBL) based on a joint likelihood analysis of 32 gamma-ray spectra for 12 blazars in the redshift range z = 0.03 to 0…
Extending the observation limits of Imaging Air Cherenkov Telescopes toward horizon
Razmik Mirzoyan, Ievgen Vovk, Michele Peresano +6
Usually the Imaging Atmospheric Cherenkov Telescopes, used for the ground-based gamma-ray astronomy in the very high energy range 50 GeV - 50 TeV, perform air shower observations t…
Deep observations of the globular cluster M15 with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +153
A population of globular clusters (GCs) has been recently established by the Fermi-LAT telescope as a new class of GeV -ray sources. Leptons accelerated to TeV energies, in the…
A Fast Very High Energy -ray Flare from BL Lacertae during a Period of Multiwavelength activity in June 2015
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +163
The mechanisms producing fast variability of the -ray emission in active galactic nuclei are under debate. The MAGIC telescopes detected a fast very high energy (VHE, E Ge…
