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, $…

Spatio-spectral-temporal Modelling of Two Young Pulsar Wind Nebulae

A. Kundu, Jagdish C. Joshi, C. Venter +5

Recent observations of a few young pulsar wind nebulae (PWNe) have revealed their morphologies in some detail. Given the availability of spatio-spectral-temporal data, we use our m…

A new method of reconstructing images of gamma-ray telescopes applied to the LST-1 of CTAO

CTA-LST Project, :, K. Abe +305

Imaging atmospheric Cherenkov telescopes (IACTs) are used to observe very high-energy photons from the ground. Gamma rays are indirectly detected through the Cherenkov light emitte…

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…

Candidate strongly lensed type Ia supernovae in the Zwicky Transient Facility archive

A. Townsend, J. Nordin, A. Sagués Carracedo +61

Gravitationally lensed type Ia supernovae (glSNe Ia) are unique astronomical tools that can be used to study cosmological parameters, distributions of dark matter, the astrophysics…

Galactic transient sources with the Cherenkov Telescope Array Observatory

Cherenkov Telescope Array Observatory Consortium

A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…

Broadband Multi-wavelength Properties of M87 during the 2018 EHT Campaign including a Very High Energy Flaring Episode

J. C. Algaba, M. Balokovic, S. Chandra +738

The nearby elliptical galaxy M87 contains one of the only two supermassive black holes whose emission surrounding the event horizon has been imaged by the Event Horizon Telescope (…

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…

The rate of extreme coronal line emitting galaxies in the Sloan Digital Sky Survey and their relation to tidal disruption events

Joseph Callow, Or Graur, Peter Clark +27

High-ionization iron coronal lines (CLs) are a rare phenomenon observed in galaxy and quasi-stellar object spectra that are thought to be created by high-energy emission from activ…

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…
