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…
High-energy neutrinos from FR0 radio-galaxies?
F. Tavecchio, C. Righi, A. Capetti +2
The sources responsible for the emission of high-energy ( 100 TeV) neutrinos detected by IceCube are still unknown. Among the possible candidates, active galactic nuclei w…
MAGIC Contributions to the 35th International Cosmic Ray Conference (ICRC2017)
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +143
MAGIC (Major Atmospheric Gamma Imaging Cherenkov) is a system of two 17 m diameter, F/1.03 Imaging Atmospheric Cherenkov Telescopes (IACT). They are dedicated to the observation of…
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…
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…
On the detectability of BL Lac objects by IceCube
C. Righi, F. Tavecchio
Since 2010 IceCube observed around 50 high-energy neutrino events of cosmic origin above 60 TeV, but the astrophysical sources of these events are still unknown. We recently propos…
Multi-filter transit observations of HAT-P-3b and TrES-3b with multiple Northern Hemisphere telescopes
Davide Ricci, Pedro Valdés Sada, Samuel Navarro-Meza +17
We present a photometric follow-up of transiting exoplanets HAT-P-3b and TrES-3b, observed by using several optical and near-infrared filters, with four small-class telescopes (D =…
The Fermi blazar sequence
G. Ghisellini, C. Righi, L. Costamante +1
We revisit the blazar sequence exploiting the complete, flux limited sample of blazars with known redshift detected by the Fermi satellite after 4 years of operations (the 3LAC sam…
On the redshift of TeV BL Lac objects
Simona Paiano, Marco Landoni, Renato Falomo +3
We report results of a spectroscopic campaign carried out at the 10 m Gran Telescopio Canarias for a sample of 22 BL Lac objects detected (or candidates) at TeV energies, aimed to…
