Indirect dark matter searches in the dwarf satellite galaxy Ursa Major II with the MAGIC telescopes
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 for indirect dark matter (DM) searches. The MAGIC telescopes carried out a deep observation campaign on UMaII between 2014 and 2016, collecting almost one hundred hours of good-quality data. [...]

Extragalactic diffuse γ-rays from dark matter annihilation: revised prediction and full modelling uncertainties
Recent high-energy data from $Fermi$-LAT on the diffuse $\gamma$-ray background have been used to set among the best constraints on annihilating TeV cold dark matter candidates. In order to assess the robustness of these limits, we revisit and update the calculation of the isotropic extragalactic $\gamma$-ray intensity from dark matter annihilation. [...]

Search for very high-energy gamma-ray emission from the microquasar Cygnus X-1 with the MAGIC telescopes
[arXiv:1708.03689]
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. [...]

A polarized fast radio burst at low Galactic latitude
[arXiv:1705.02911]
We report on the discovery of a new fast radio burst (FRB), FRB 150215, with the Parkes radio telescope on 2015 February 15. The burst was detected in real time with a dispersion measure (DM) of 1105.6 ± 0.8 pc cm$^{−3}$, a pulse duration of 2.8 $^{+1.2}_{-0.5}$ ms, and a measured peak flux density assuming that the burst was at beam centre of 0.7$^{+0.2}_{-0.1}$ Jy.

The Tunka-Grande experiment
The investigation of energy spectrum and mass composition of primary cosmic rays in the energy range 10$^{16}$–10$^{18}$ eV and the search for diffuse cosmic gamma rays are of the great interest for understanding mechanisms and nature of high-energy particle sources, the problem of great importance in modern astrophysics. Tunka-Grande scintillator array is a part of the experimental complex TAIGA (Tunka Advanced Instrument for Cosmic Ray and Gamma Astronomy) which is located in the Tunka Valley, about 50 km from Lake Baikal.

MAGIC observations of the microquasar V404 Cygni during the 2015 outburst
[arXiv:1707.00887]
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 activity from this source, observations at several wavelengths were conducted. [...]

A cut-off in the TeV gamma-ray spectrum of the SNR Cassiopeia A
[arXiv:1707.01583]
It is widely believed that the bulk of the Galactic cosmic rays is accelerated in supernova remnants (SNRs). However, no observational evidence of the presence of particles of PeV energies in SNRs has yet been found. [...]

Very-high-energy gamma-ray observations of the Type Ia Supernova SN 2014J with the MAGIC telescopes
[arXiv:1702.07677]
In this work we present data from observations with the MAGIC telescopes of SN 2014J detected on January 21 2014, the closest Type Ia supernova since Imaging Air Cherenkov Telescopes started to operate.Aims. We aim to probe the possibility of very-high-energy (VHE; E ≥ 100 GeV) gamma rays produced in the early stages of Type Ia supernova explosions.Methods. [...]
