Revisiting EBL Constraints from Gamma-Ray Observations: A Critical Assessment and Methodological Improvements
K. Abe, S. Abe, J. Abhir +185
The extragalactic background light (EBL), ranging from the infrared to the ultraviolet bands, is the second most intense photon field in the universe, surpassed only by the cosmic…
First detection of VHE gamma-ray signal from the FSRQ TON 0599
MAGIC Collaboration, K. Abe, S. Abe +245
TON\,0599 (z=0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, \,GeV) gamma-ray band. Its redshift makes it currently o…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
Very-high-energy gamma-ray detection and long-term multi-wavelength view of the flaring blazar B2 1811+31
K. Abe, S. Abe, J. Abhir +231
Among the blazars whose emission has been detected up to very-high-energy (VHE; 100 GeV < E < 100 TeV) gamma rays, intermediate synchrotron-peaked BL Lacs (IBLs) are quite rare. Th…
Multi-wavelength study of OT 081: broadband modelling of a transitional blazar
MAGIC Collaboration, H. Abe, S. Abe +270
OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…
Insights from the first flaring activity of a high-synchrotron-peaked blazar with X-ray polarization and VHE gamma rays
MAGIC Collaboration, K. Abe, S. Abe +250
We study a flaring activity of the HSP Mrk421 that was characterized from radio to very-high-energy (VHE; E TeV) gamma rays with MAGIC, Fermi-LAT, Swift, XMM-Newton and sever…
Combined search in dwarf spheroidal galaxies for branon dark matter annihilation signatures with the MAGIC telescopes
MAGIC Collaboration
Massive brane fluctuations, called branons, behave as weakly interacting massive particles, which is one of the most favored class of candidates to fulfill the role of the dark mat…
Constraints on VHE gamma-ray emission of Flat Spectrum Radio Quasars with the MAGIC telescopes
MAGIC Collaboration
Flat spectrum radio quasars (FSRQs) constitute a class of jetted active galaxies characterized by a very luminous accretion disk, prominent and rapidly moving line-emitting cloud s…
The variability patterns of the TeV blazar PG 1553+113 from a decade of MAGIC and multi-band observations
MAGIC Collaboration, H. Abe, S. Abe +264
PG 1553+113 is one of the few blazars with a convincing quasi-periodic emission in the gamma-ray band. The source is also a very high-energy (VHE; >100 GeV) gamma-ray emitter. To b…
MAGIC detection of GRB 201216C at
H. Abe, S. Abe, V. A. Acciari +217
Gamma-ray bursts (GRBs) are explosive transient events occurring at cosmological distances, releasing a large amount of energy as electromagnetic radiation over several energy band…
Multi-year characterisation of the broad-band emission from the intermittent extreme BL Lac 1ES~2344+514
H. Abe, S. Abe, V. A. Acciari +232
The BL Lac 1ES 2344+514 is known for temporary extreme properties (e.g., a shift of the synchrotron SED peak energy above 1keV). While those extreme states were so fa…
Search for Gamma-ray Spectral Lines from Dark Matter Annihilation up to 100 TeV towards the Galactic Center with MAGIC
MAGIC Collaboration, H. Abe, S. Abe +210
Line-like features in TeV -rays constitute a ''smoking gun'' for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov t…
MAGIC observations provide compelling evidence of the hadronic multi-TeV emission from the putative PeVatron SNR G106.3+2.7
MAGIC Collaboration, H. Abe, S. Abe +214
The SNR G106.3+2.7, detected at 1--100 TeV energies by different -ray facilities, is one of the most promising PeVatron candidates. This SNR has a cometary shape which can be di…
Long-term multi-wavelength study of 1ES 0647+250
MAGIC Collaboration, V. A. Acciari, T. Aniello +217
The BL Lac object 1ES 0647+250 is one of the few distant -ray emitting blazars detected at very high energies (VHE, 100 GeV) during a non-flaring state. It was detected…
Gamma-ray observations of MAXI J1820+070 during the 2018 outburst
H. Abe, S. Abe, V. A. Acciari +439
MAXI J1820+070 is a low-mass X-ray binary with a black hole as a compact object. This binary underwent an exceptionally bright X-ray outburst from March to October 2018, showing ev…
Multi-messenger characterization of Mrk 501 during historically low X-ray and -ray activity
MAGIC collaboration, H. Abe, S. Abe +322
We study the broadband emission of Mrk 501 using multi-wavelength observations from 2017 to 2020 performed with a multitude of instruments, involving, among others, MAGIC, Fermi-LA…
