Prospects for detecting eV-scale sterile neutrinos from a galactic supernova [PDF]
Future neutrino detectors will obtain high-statistics data from a nearby core-collapse supernova. We study the mixing with eV-mass sterile neutrinos in a supernova environment and its effects on the active neutrino fluxes as detected by Hyper-Kamiokande ...

A primer on axion physics, emphasizing an intuitive understanding of why the axion solves the strong CP problem. Abstract The canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields.

Neutrino-nucleus reactions and their role for supernova dynamics and nucleosynthesis
The description of nuclear reactions induced by supernova neutrinos has witnessed significant progress during the recent years. At the energies and momentum transfers relevant for supernova neutrinos neutrino-nucleus cross sections are dominated by ...

Chiral transport of neutrinos in supernovae
The conventional neutrino transport theory for core-collapse supernovae misses one key property of neutrinos: the left-handedness. The chirality of neutrinos modifies the hydrodynamic behavior at the macroscopic scale and leads to topological transport ...

New effects of non-standard self-interactions of neutrinos in a supernova [PDF]
Neutrino self-interactions are known to lead to non-linear collective flavor oscillations in a core-collapse supernova. We point out new possible effects of non-standard self-interactions (NSSI) of neutrinos on flavor conversions in a two-flavor ...

Nuclear astrophysicists at war
The Manhattan program not only opened the path to the nuclear age for humans, but also triggered a lot of new questions and research directions in nuclear physics and astrophysics that still inform the ideas in these fields today. Abstract The question of energy production in stars stimulated an entire generation of young physicists in the 1930s who ...

Supernova neutrinos in SK-Gd and other experiments
Now many detectors are waiting for core-collapse supernovae in or near our galaxy. If they occur in our galaxy we will be able to reveal the mechanism of supernova explosions and also be able to access the properties of neutrinos, such as mass hierarchy.

Seltene und extreme Supernovae
Robotische Teleskope entdecken eine zunehmende Vielfalt transienter Strahlungsquellen, deren ungewöhnliche Eigenschaften neue Arten von Sternexplosionen nahelegen. Obwohl die absolute Häufigkeit solcher Ereignisse sehr klein ist, erlaubt ihre extreme Helligkeit relativ häufige Sichtungen, stellt aber theoretische Modelle vor große Herausforderungen ...

Probing nonstandard neutrino interactions with supernova neutrinos [PDF]
We analyze the possibility of probing non-standard neutrino interactions (NSI, for short) through the detection of neutrinos produced in a future galactic supernova (SN).We consider the effect of NSI on the neutrino propagation through the SN envelope within a three-neutrino framework, paying special attention to the inclusion of NSI-induced resonant ...

Combined Pre-supernova Alert System with KamLAND and Super-Kamiokande
Preceding a core-collapse supernova (CCSN), various processes produce an increasing amount of neutrinos of all flavors characterized by mounting energies from the interior of massive stars.
