Detection of TeV emission during early afterglow from poorly localized GRBs with ground based IACTs
S. Macera, B. Banerjee, M. Seglar-Arroyo +10
Gamma-ray bursts (GRBs) are among the most luminous and rapidly evolving transients in the Universe. While space-based instruments have extended GRB observations up to energies of…
A bright megaelectronvolt emission line in -ray burst GRB 221009A
Maria Edvige Ravasio, Om Sharan Salafia, Gor Oganesyan +13
The highly variable and energetic pulsed emission of a long gamma-ray burst (GRB) is thought to originate from local, rapid dissipation of kinetic or magnetic energy within an ultr…
Flaring activity from magnetic reconnection in BL Lacertae
S. Agarwal, B. Banerjee, A. Shukla +7
The evolution of the spectral energy distribution during flares constrains models of particle acceleration in blazar jets. The archetypical blazar BL Lac provided a unique opportun…
Pre-merger alert to detect the very-high-energy prompt emission from binary neutron-star mergers: Einstein Telescope and Cherenkov Telescope Array synergy
Biswajit Banerjee, Gor Oganesyan, Marica Branchesi +8
The current generation of very-high-energy ray (VHE; E above 30 GeV) detectors (MAGIC and H.E.S.S.) have recently demonstrated the ability to detect the afterglow emission…
Neutrino search from γ-ray bursts during the prompt and X-ray afterglow phases using 10 years of IceCube public data
Francesco Lucarelli, Gor Oganesyan, Teresa Montaruli +5
Neutrino emission from gamma-ray bursts (GRBs) has been sought for a long time, and stringent limits on the most accredited GRB emission models have been obtained from IceCube. Mul…
Perspectives for multi-messenger astronomy with the next generation of gravitational-wave detectors and high-energy satellites
Samuele Ronchini, Marica Branchesi, Gor Oganesyan +6
The Einstein Telescope (ET) is going to bring a revolution for the future of multi-messenger astrophysics. In order to detect the counterparts of binary neutron star (BNS) mergers…
