Time-dependent modelling of short-term variability in the TeV-blazar VER J0521+211 during the major flare in 2020
MAGIC Collaboration, S. Abe, J. Abhir +228
The BL Lacertae object VER J0521+211 underwent a notable flaring episode in February 2020. A short-term monitoring campaign, led by the MAGIC (Major Atmospheric Gamma Imaging Chere…
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, $…
Standardised formats and open-source analysis tools for the MAGIC telescopes data
S. Abe, J. Abhir, A. Abhishek +208
Instruments for gamma-ray astronomy at Very High Energies () have traditionally derived their scientific results through proprietary data and software. Data stand…
Markarian Multiwavelength Data Center (MMDC): A Tool for Retrieving and Modeling Multi-temporal, Multi-wavelength and Multi-messenger Data from Blazar Observations
N. Sahakyan, V. Vardanyan, P. Giommi +7
The Markarian Multiwavelength Data Center (MMDC) is a web-based tool designed for accessing and retrieving multiwavelength and multimessenger data from blazar observations. MMDC fa…
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 Lorentz invariance violation from the extraordinary Mrk 421 flare of 2014 using a novel analysis method
MAGIC Collaboration, S. Abe, J. Abhir +214
The Lorentz Invariance Violation (LIV), a proposed consequence of certain quantum gravity (QG) scenarios, could instigate an energy-dependent group velocity for ultra-relativistic…
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…
Modeling blazar broadband emission with convolutional neural networks -- II. External Compton model
N. Sahakyan, D. Bégué, A. Casotto +6
In the context of modeling spectral energy distributions (SEDs) for blazars, we extend the method that uses a convolutional neural network (CNN) to include external inverse Compton…
Performance and first measurements of the MAGIC Stellar Intensity Interferometer
MAGIC Collaboration, S. Abe, J. Abhir +217
In recent years, a new generation of optical intensity interferometers has emerged, leveraging the existing infrastructure of Imaging Atmospheric Cherenkov Telescopes (IACTs). The…
Broadband Study of Gamma-Ray Blazars at Redshifts
N. Sahakyan, G. Harutyunyan, S. Gasparyan +1
High redshift blazars are among the most powerful non-explosive sources in the Universe and play a crucial role in understanding the evolution of relativistic jets. To understand t…
Constraints on axion-like particles with the Perseus Galaxy Cluster with MAGIC
MAGIC Collaboration, H. Abe, S. Abe +211
Axion-like particles (ALPs) are pseudo-Nambu-Goldstone bosons that emerge in various theories beyond the standard model. These particles can interact with high-energy photons in ex…
