Flux Distribution of Gamma-Ray Emission in Blazars: The Example of Mrk 501
Carlo Romoli, Nachiketa Chakraborty, Daniela Dorner +2
Flux distribution is an important tool to understand the variability processes in active galactic nuclei. We now have available a great deal of observational evidences pointing tow…
Discovery of TeV -ray emission from the neighbourhood of the supernova remnant G24.7+0.6 by MAGIC
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +151
SNR G24.7+0.6 is a 9.5 kyrs radio and -ray supernova remnant evolving in a dense medium. In the GeV regime, SNR G24.7+0.6 (3FHL\,J1834.1--0706e/FGES\,J1834.1--0706) shows a hard…
Periastron Observations of TeV Gamma-Ray Emission from a Binary System with a 50-year Period
The VERITAS Collaboration, A. U. Abeysekara, W. Benbow +212
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 VERITAS and MAGIC imaging atmosphe…
Constraining very-high-energy and optical emission from FRB 121102 with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +155
Fast radio bursts (FRBs) are bright flashes observed typically at GHz frequencies with millisecond duration, whose origin is likely extragalactic. Their nature remains mysterious,…
The extreme HBL behaviour of Markarian 501 during 2012
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +276
A multiwavelength campaign was organized to take place between March and July of 2012. Excellent temporal coverage was obtained with more than 25 instruments, including the MAGIC,…
The blazar TXS 0506+056 associated with a high-energy neutrino: insights into extragalactic jets and cosmic ray acceleration
S. Ansoldi, L. A. Antonelli, C. Arcaro +146
A neutrino with energy of 290 TeV, IceCube-170922A, was detected in coincidence with the BL Lac object TXS~0506+056 during enhanced gamma-ray activity, with chance coincidenc…
Multi-messenger observations of a flaring blazar coincident with high-energy neutrino IceCube-170922A
The IceCube, Fermi-LAT, MAGIC +13
Individual astrophysical sources previously detected in neutrinos are limited to the Sun and the supernova 1987A, whereas the origins of the diffuse flux of high-energy cosmic neut…
The broad-band properties of the intermediate synchrotron peaked BL Lac S2 0109+22 from radio to VHE gamma rays
MAGIC Collaboration, S. Ansoldi, L. A. Antonelli +163
The MAGIC telescopes observed S2 0109+22 in 2015 July during its flaring activity in high energy gamma rays observed by Fermi-LAT. We analyse the MAGIC data to characterise the ver…
Multi-wavelength characterization of the blazar S5~0716+714 during an unprecedented outburst phase
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +187
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 obs…
Gamma-ray flaring activity of NGC 1275 in 2016-2017 measured by MAGIC
MAGIC collaboration, S. Ansoldi, L. A. Antonelli +152
We report on the detection of flaring activity from the Fanaroff-Riley I radio galaxy NGC 1275 in very-high-energy (VHE, E 100 GeV) gamma rays with the MAGIC telescopes. Observ…
Constraining Dark Matter lifetime with a deep gamma-ray survey of the Perseus Galaxy Cluster with MAGIC
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +148
Clusters of galaxies are the largest known gravitationally bound structures in the Universe, with masses around , most of it in the form of dark matter. The groun…
The detection of the blazar S4 0954+65 at very-high-energy with the MAGIC telescopes during an exceptionally high optical state
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +169
The very-high-energy (VHE, GeV) -ray MAGIC observations of the blazar S4 0954+65, were triggered by an exceptionally high flux state of emission in the optical. Th…
