Testing CPT Symmetry with Supernova Neutrinos

open access: yes, 2005
Diagnosing core of supernova requires favor-dependent reconstruction of three species of neutrino spectra, \nu_e, \bar{\nu}_{e} and \nu_x (a collective notation for \nu_{\mu}, \bar{\nu}_{\mu}, \nu_{\tau}, and \bar{\nu}_{\tau}).

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers

open access: yesAnnalen der Physik, Volume 536, Issue 2, February 2024.
Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Cosmic-Ray Boosted Diffuse Supernova Neutrinos

open access: yesAstronomy
The subject of boosted fluxes of dark matter or cosmic relic neutrinos via scattering on cosmic rays has received considerable attention recently. This article investigates the boosted neutrino flux from the scattering of cosmic rays and the so-far ...

Chiral transport of neutrinos in supernovae

open access: yesEPJ Web of Conferences, 2017
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 ...

Primer on Axion Physics

open access: yesAnnalen der Physik, Volume 536, Issue 1, January 2024.
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.

Detection of Supernova Neutrinos

open access: yes, 2004
Matter effects on neutrino oscillations in both, a supernova and the Earth, change the observed supernova neutrino spectra. We calculate the expected number of supernova neutrino interactions for ICARUS, SK and SNO detectors as a function of the distance which they traveled in the Earth.

Nuclear astrophysicists at war

open access: yesNatural Sciences, Volume 4, Issue 1, January 2024.
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 ...

Combined Pre-supernova Alert System with KamLAND and Super-Kamiokande

open access: yesThe Astrophysical Journal
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.

Neutrino astrophysics : recent advances and open issues

open access: yes, 2015
We highlight recent advances in neutrino astrophysics, the open issues and the interplay with neutrino properties. We emphasize the important progress in our understanding of neutrino flavor conversion in media. We discuss the case of solar neutrinos, of

Seltene und extreme Supernovae

open access: yesPhysik in unserer Zeit, Volume 55, Issue 1, Page 40-46, January 2024.
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 ...
