Observation of inverse Compton emission from a long -ray burst
V. A. Acciari, S. Ansoldi, L. A. Antonelli +301
Long-duration gamma-ray bursts (GRBs) originate from ultra-relativistic jets launched from the collapsing cores of dying massive stars. They are characterised by an initial phase o…
Exploring the physics behind the non-thermal emission from star-forming galaxies detected in gamma rays
P. Kornecki, E. Peretti, S. del Palacio +2
Star-forming galaxies (SFGs) emit non-thermal radiation from radio to gamma-rays. We aim to investigate the main mechanisms of global CR transport and cooling in SFGs. The way they…
The first days of type II-P core collapse supernovae in the gamma-ray range
P. Cristofari, A. Marcowith, M. Renaud +5
Type II-P supernovæ~(SNe), the most common core-collapse SNe type, result from the explosions of red supergiant stars. Their detection in the radio domain testifies of the presenc…
Modeling gamma-ray signatures of particle acceleration in stellar clusters from GeV to PeV
A. Inventar, S. Gabici, E. Peretti
Young massive stellar clusters (YMSCs) have recently regained interest as PeVatron candidates, potentially accounting for the cosmic-ray (CR) knee as alternatives to isolated super…
ASTRI Mini-Array Core Science at the Observatorio del Teide
S. Vercellone, C. Bigongiari, A. Burtovoi +84
The ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) Project led by the Italian National Institute for Astrophysics (INAF) is developing and will deploy at the Obse…
The galactic bubbles of starburst galaxies The influence of galactic large-scale magnetic fields
Z. Meliani, P. Cristofari, A. Rodriguez-Gonzalez +3
Context. The galactic winds of starburst galaxies (SBGs) give rise to remarkable structures on kiloparsec scales. However, the evolution and shape of these giant wind bubbles, as w…
High-energy neutrinos from the vicinity of the supermassive black hole in NGC 1068
P. Padovani, E. Resconi, M. Ajello +12
We present a comprehensive multi-messenger study of NGC 1068, the prototype Seyfert II galaxy recently associated with high-energy IceCube neutrinos. Various aspects of the source,…
Chasing Gamma-Ray Signals from Binary Neutron Star Coalescences with the Cherenkov Telescope Array: Prospects and Observing Strategies
S. Abe, J. Abhir, A. Abhishek +457
The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…
Very-high-energy observations of the Seyfert galaxy NGC 4151 with MAGIC -- Indication of another gamma-ray obscured candidate neutrino source
K. Abe, S. Abe, J. Abhir +207
Seyfert galaxies are emerging as a promising source class of high-energy neutrinos. The Seyfert galaxies NGC 4151 and NGC 1068 have come up respectively as the most promising count…
Very High Energy Gamma Rays from Ultra Fast Outflows
B. Le Nagat Neher, E. Peretti, P. Cristofari +1
Context. Ultra fast outflows (UFOs) from active galactic nuclei (AGN) are expected to lead to the formation of sub-relativistic strong shocks expanding in a dense circumnuclear med…
