Observing Supernova Neutrino Light Curves with Super-Kamiokande. IV. Development of SPECIAL BLEND: A New Public Analysis Code for Supernova Neutrinos [PDF]
The Astrophysical Journal, 2023 Supernova neutrinos are invaluable signals that offer information about the interior of supernovae. Because a nearby supernova can occur at any time, preparing for future supernova neutrino observation is an urgent task.

Limits on heavy neutral leptons, Z ′ bosons and majorons from high-energy supernova neutrinos [PDF]
Journal of High Energy Physics, 2023 Light hypothetical particles with masses up to O 100 $$ \mathcal{O}(100) $$ MeV can be produced in the core of supernovae. Their subsequent decays to neutrinos can produce a flux component with higher energies than the standard flux.

Probing non-standard neutrino interactions with a light boson from next galactic and diffuse supernova neutrinos [PDF]
Journal of High Energy Physics, 2022 Non-standard neutrino interactions with a massive boson can produce the bosons in the core of core-collapse supernovae (SNe). After the emission of the bosons from the SN core, their subsequent decays into neutrinos can modify the SN neutrino flux.

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 ...

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.

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 ...

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.

Strong Supernova 1987A Constraints on Bosons Decaying to Neutrinos. [PDF]
Physical Review Letters, 2022 Majoron-like bosons would emerge from a supernova (SN) core by neutrino coalescence of the form νν→ϕ and ν[over ¯]ν[over ¯]→ϕ with 100-MeV-range energies.
