Muography is a recent technique in particle physics where atmospheric muons are used to study the interior of large targets such as volcanoes. In the case of transmission muography, a detector is used to count and track muons that survive after propagation through the target. To a first approximation, the number of muons that survive after propagation through the target depends directly on the...
Incoming large-scale radio experiments for cosmic-ray detection require to run massive air-shower simulations to evaluate the radio-signal at any antenna position. The modeling of the radio-emission can be performed either based on microscopic or macroscopic approaches. The former is fast but relies on many free parameters that limits accuracy, the latter consists of Monte-Carlo simulations...
The Pierre Auger Observatory is the largest cosmic-ray observatory to date. It has been built in order to study the most energetic particles in the universe, commonly known as Ultra High Energy Cosmic Rays (UHECR). With a surface of 3,000$\,{\rm km^{2}}$(30 times Paris), the observatory detects cosmic rays from $10^{17.5}\text{ to }10^{20.5}\,{\rm eV}$. The energy, the shower depth ${\rm...
The Large Sized Telescope (LST) prototype is currently under commissioning at La Palma. It's the first on-site telescope of the Cherenkov Telescope Array (CTA). CTA is the new generation of Imaging Atmospheric Cherenkov Telescopes (IACT) for the ground based detection of Very High-Energy gamma-ray (VHE).
GRBs are short explosions, they are one the most energetic phenomena in the universe....
We perform a joint gravitational waves/gamma-ray bursts (GW/GRB) Bayesian analysis in order to put constraints on the low-luminosity end of the short gamma-ray burst (sGRB) population. For this purpose we exploit the results of the modeled search for GW transients associated to short and ambiguous GRBs detected during the O1, O2, O3a and O3b runs of the LIGO/Virgo network and a broken power...
TeV halos are astrophysical objects recently discovered by the H.AW.C. which extend around pulsars. These sources are electron and positron accelerators that interact with the surrounding magnetic field. Their recent detection is due to the fact that they are only visible in the gamma ray region, their size represents several degrees in the sky and they are very faint. To study them, it is...
