Magnetized Shocks Mediated by Radiation from Leptonic and Hadronic Processes
Shunke Ai, Irene Tamborra
Shocks in astrophysical transients are key sites of particle acceleration. If the shock upstream is optically thick, radiation smoothens the velocity discontinuity at the shock (ra…
Steady state of fast-oscillating neutrinos in an inhomogeneous medium
Manuel Goimil-García, Irene Tamborra
The streaming of neutrinos in an inhomogeneous medium is known to affect the physics of flavor conversion. We employ an ensemble of single-crossed angular distributions and explore…
Neutrinos from stars in the Milky Way
Pablo Martínez-Miravé, Irene Tamborra
Neutrinos are produced during stellar evolution by means of thermal and thermonuclear processes. We model the cumulative neutrino flux expected at Earth from all stars in the Milky…
Collapsar Disk Outflows III: Detectable Neutrino and Gravitational Wave Signatures
Rodrigo Fernández, Silas Janke, Coleman Dean +1
We investigate the neutrino and gravitational wave (GW) signals from accretion disks formed during the failed collapse of a rotating massive star (a collapsar). Following black hol…
Electron-neutrino lepton number crossings: Variations with the supernova core physics
Marie Cornelius, Irene Tamborra, Malte Heinlein +2
A crucial ingredient affecting fast neutrino flavor conversion in core-collapse supernovae (SNe) is the shape of the angular distribution of the electron-neutrino lepton number (EL…
Diagnosing electron-neutrino lepton number crossings in core-collapse supernovae: A comparison of methods
Marie Cornelius, Irene Tamborra, Malte Heinlein +1
Fast neutrino flavor conversion may impact the explosion mechanism and nucleosynthesis in core-collapse supernovae. A necessary condition for fast flavor conversion is the presence…
Neutrino quantum kinetics in three flavors
Shashank Shalgar, Irene Tamborra
The impact of neutrino flavor conversion on the supernova mechanism is yet to be fully understood. We present multi-energy and multi-angle solutions of the neutrino quantum kinetic…
Identifying Thorne-Żytkow Objects through Neutrinos
Pablo Martínez-Miravé, Irene Tamborra, Alejandro Vigna-Gómez
Thorne-Żytkow Objects (TŻOs) have been predicted to form when a neutron star is engulfed by a diffuse, convective giant envelope. Accretion onto a neutron star at a rate that is la…
