Abstract The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions various possible theories gravity put to test, where a clear signal properties is still missing. dawn multi-messenger high-energy astrophysics tremendously beneficial, as it allows us study particles with much higher energies travelling longer distances than in terrestrial experiments, but more progress needed on several fronts. A thorough appraisal current...

The fact that the standard dispersion relation for photons in vacuum could be modified because of their interaction with quantum nature spacetime has been proposed more than two decades ago. A quantitative model [Jacob \& Piran, JCAP 01, 031 (2008)], tested extensively using distant highly energetic astrophysical sources, searching energy-dependent time delays photon arrival times. Since no delay was firmly measured, lower limits were set on energy scale $\Lambda$ related to these effects....
High energy photons from astrophysical sources are unique probes for some predictions of candidate theories Quantum Gravity (QG). In particular, Imaging atmospheric Cherenkov telescope (IACTs) instruments optimised astronomical observations in the range spanning a few tens GeV to ∼100 TeV, which makes them excellent search effects QG. this article, we will review QG can be tested with IACTs, most notably Lorentz invariance violation (LIV) and its consequences. It is often represented...
Signal estimation in the presence of background noise is a common problem several scientific disciplines. An ``on/off'' measurement performed when itself not known, being estimated from control sample. The ``frequentist'' and Bayesian approaches for signal on/off measurements are reviewed compared, focusing on weakness former advantages latter correctly addressing Poissonian nature problem. In this work, we devise novel reconstruction method, analysis including single-event likelihoods...
BL Lacertae (BL Lac) is one of the low-frequency peaked Lac object (LBL). Since August 2020, has shown a historically high activity in HE (high-energy, 0.1 GeV < E 100 GeV) gamma-ray and optical bands. The MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescopes performed joint observations during this flaring period with instruments operating gamma-ray, X-ray, optical, radio bands from to October 2020. In VHE (very- high-energy, > range, was detected several nights an especially...
We present the first search for dark matter (DM) spectral lines in Galactic centre (GC) region with MAGIC telescopes. The telescopes, located on Canary island of La Palma (Spain), are sensitive to gamma rays energy range from 50 GeV TeV. has performed indirect DM searches various astrophysical targets, such as dwarf spheroidal galaxies and clusters galaxies. Observations at high zenith angles significantly increase telescopes' collection area sensitivity TeV regime. results obtained more...
Gamma rays constitute a privileged point of view for the study extreme Universe. Unlike charged cosmic rays, which are thought to have common origin, gamma not deflected by galactic and intergalactic magnetic fields. This offers opportunity unveil most powerful particle accelerators, still largely unknown, once modifications in gamma-ray flux, arrival time, angular distribution due propagation effects considered. ray telescopes include large variety instruments, both satellite-born...
This manuscript presents the lecture notes of a course given during second training school COST Action CA18108 "Quantum gravity phenomenology in multi-messenger approach", which occurred Belgrade September 2022. It aims to provide comprehensive introduction on various aspects data acquisition and analysis context high-energy gamma-ray astrophysics. A special effort was made so that these can be understood by PhD students with no background instrumentation or So is kept short enough, choice...
Signal estimation in the presence of background noise is a common problem many scientific disciplines. An “On/Off” measurement when itself imprecisely measured, which case for instance observations performed astronomy. We propose new method estimating signal rate based on Bayesian formalism. It uses information single-event variables and their distribution population. Events are thereby weighted according to likelihood being or event suppression can be achieved without performing data...
Among the many activities organized by Outreach working group of MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) Collaboration, we would like to present ongoing project #meetTheMAGICians. Under this hashtag, used on our social media pages (@MAGICtelescopes), collect live streaming events astroparticle physics topics, series posts, videos and other contents. In addition increasing visibility collaboration, a central goal #meetTheMAGICians is strongly connect communication science...
