VHE gamma-ray detection of FSRQ QSO B1420+326 and modeling of its enhanced broadband state in 2020
V. A. Acciari, S. Ansoldi, L. A. Antonelli +230
Context. QSO B1420+326 is a blazar classified as a Flat Spectrum Radio Quasar (FSRQ). In the beginning of 2020 it underwent an enhanced flux state. An extensive multiwavelength cam…
Observation of a sudden cessation of a very-high-energy gamma-ray flare in PKS 1510-089 with H.E.S.S. and MAGIC in May 2016
H. E. S. S. Collaboration, H. Abdalla, R. Adam +430
The flat spectrum radio quasar (FSRQ) PKS 1510-089 is known for its complex multiwavelength behavior, and is one of only a few FSRQs detected at very high energy (VHE, GeV…
MAGIC observations of the nearby short gamma-ray burst GRB 160821B
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +188
The coincident detection of GW170817 in gravitational waves and electromagnetic radiation spanning the radio to MeV gamma-ray bands provided the first direct evidence that short ga…
Detection of the Geminga pulsar with MAGIC hints at a power-law tail emission beyond 15 GeV
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +190
We report the detection of pulsed gamma-ray emission from the Geminga pulsar (PSR J0633+1746) between GeV and GeV. This is the first time a middle-aged pulsar has been…
An intermittent extreme BL Lac: MWL study of 1ES 2344+514 in an enhanced state
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +215
Extreme High-frequency BL~Lacs (EHBL) feature their synchrotron peak of the broadband spectral energy distribution (SED) at 10\,Hz. The BL~Lac object 1ES~23…
Studying the nature of the unidentified gamma-ray source HESS J1841-055 with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +184
We investigate the physical nature and origin of the gamma-ray emission from the extended source HESS J1841-055 observed at TeV and GeV energies. We observed HESS J1841-055 at TeV…
Testing two-component models on very-high-energy gamma-ray emitting BL Lac objects
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +201
Context. It has become evident that one-zone synchrotron self-Compton models are not always adequate for very-high-energy (VHE) gamma-ray emitting blazars. While two-component mode…
Unravelling the complex behavior of Mrk 421 with simultaneous X-ray and VHE observations during an extreme flaring activity in April 2013
MAGIC collaboration, V. A. Acciari, S. Ansoldi +237
We report on a multi-band variability and correlation study of the TeV blazar Mrk 421 during an exceptional flaring activity observed from 2013 April 11 to 2013 April 19. The study…
Bounds on Lorentz invariance violation from MAGIC observation of GRB 190114C
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +181
On January 14, 2019, the Major Atmospheric Gamma Imaging Cherenkov telescopes detected GRB 190114C above 0.2 TeV, recording the most energetic photons ever observed from a gamma-ra…
