Nuclear Physics B - Proceedings Supplements, 2007 A nascent neutron star resulting from stellar collapse is a prodigious source of neutrinos of all flavors. While the most basic features of this neutrino emission can be estimated from simple considerations, the detailed simulation of the neutrinos' decoupling from the hot neutron star is not yet computationally tractable in its full glory, being a ...

Collisional Triggering of Fast Flavor Conversions of Supernova Neutrinos [PDF]
Physical Review Letters, 2019 Fast flavor conversions of supernova neutrinos, possible near the neutrinosphere, depends on an interesting interplay of collisions and neutrino oscillations.

Neutrinos from core-collapse supernovae at KM3NeT [PDF]
EPJ Web of Conferences, 2023 The SN1987A supernova was the first extragalactic neutrino de- tection, but no further observations have been made since. Detecting neutrinos from a galactic supernova would provide invaluable information on the supernova mechanism and particle behavior ...

Resonances of Supernova Neutrinos in Twisting Magnetic Fields. [PDF]
Physical Review Letters, 2023 We investigate the effect of resonant spin conversion of the neutrinos induced by the geometrical phase in a twisting magnetic field. We find that the geometrical phase originating from the rotation of the transverse magnetic field along the neutrino ...

Collisional Flavor Instabilities of Supernova Neutrinos. [PDF]
Physical Review Letters, 2021 A lingering mystery in core-collapse supernova theory is how collective neutrino oscillations affect the dynamics. All previously identified flavor instabilities, some of which might make the effects considerable, are essentially collisionless phenomena.

Rocks, water, and noble liquids: Unfolding the flavor contents of supernova neutrinos [PDF]
Physical Review D, 2022 Measuring core-collapse supernova neutrinos, both from individual supernovae within the Milky Way and from past core collapses throughout the Universe (the diffuse supernova neutrino background, or DSNB), is one of the main goals of current and next ...

Boosted dark matter from diffuse supernova neutrinos [PDF]
, 2021 The XENON collaboration recently reported an excess of electron recoil events in the low energy region with a significance of around 3.3σ. An explanation of this excess in terms of thermal dark matter seems challenging.

Supernova simulations confront SN 1987A neutrinos [PDF]
Physical Review D, 2023 We return to interpreting the historical SN~1987A neutrino data from a modern perspective. To this end, we construct a suite of spherically symmetric supernova models with the Prometheus-Vertex code, using four different equations of state and five ...

RES-NOVA sensitivity to core-collapse and failed core-collapse supernova neutrinos [PDF]
, 2021 RES-NOVA is a new proposed experiment for the investigation of astrophysical neutrino sources with archaeological Pb-based cryogenic detectors. RES-NOVA will exploit Coherent Elastic neutrino-Nucleus Scattering (CEνNS) as detection channel, thus it will ...
