Ultraviolet radiation and neutrinos: two messengers from CCSNe in the CSM scenario
Silvia Gagliardini, Simone Dall'Osso, Dafne Guetta +4
Massive stars (>8 ) often undergo intense mass loss through winds or eruptive events in the final stages of their evolution, leading to the formation of a dense circumst…
Hunting for newborn magnetars: a multi-messenger approach
Dafne Guetta, Simone Dall'Osso
We carry out a numerical calculation of magnetar-powered shock break-outs (SBOs) and supernova (SN) light-curves. In particular, we investigate the impact of gravitational wave (GW…
Luminosity Selection for Gamma Ray Burst
Shreya Banerjee, Dafne Guetta
There exists an inevitable scatter in intrinsic luminosity of Gamma Ray Bursts(GRBs). If there is relativistic beaming in the source, viewing angle variation necessarily introduces…
Estimating the Neutrino Flux from Choked Gamma-Ray Bursts
Michela Fasano, Silvia Celli, Dafne Guetta +3
The strong constraints from the Fermi-LAT data on the isotropic gamma-ray background suggest that the neutrinos observed by IceCube might possibly come from sources that are hidden…
Multimessenger Probes of High-energy Sources
Dafne Guetta
Multimessenger observations may hold the key to learn about the most energetic sources in the universe. The recent construction of large scale observatories opened new possibilitie…
Constraining the Fraction of Core-Collapse Supernovae Harboring Choked Jets with High-energy Neutrinos
Dafne Guetta, Roi Rahin, Imre Bartos +1
The joint observation of core-collapse supernovae with gamma-ray bursts shows that jets can be launched in the aftermath of stellar core collapse, likely by a newly formed black ho…
