Turbulence and supernova neutrinos

, 2011
As neutrinos propagate from the neutrinosphere through the mantle of a core-collapse supernova they will pass through regions of turbulence. The turbulence leads to stochastic neutrino flavor mixing thus leaving fingerprints in the Galactic supernova ...

Gravitational lensing of supernova neutrinos [PDF]

, 2006
The black hole at the center of the galaxy is a powerful lens for supernova neutrinos. In the very special circumstance of a supernova near the extended line of sight from Earth to the galactic center, lensing could dramatically enhance the neutrino flux

Testing the Weak Cosmic Censorship Conjecture via Test Particle–Induced Overcharging/Overspinning of Kerr–Newman–Modified Gravity Black Hole

Advances in Astronomy, Volume 2026, Issue 1, 2026.
We examine the weak cosmic censorship conjecture (WCCC) violation by throwing a charged and rotating test particle into a Kerr–Newman–modified gravity black hole (KN–MOG BH). The result depends on several factors, such as the relative sign of the particle’s charge and its direction of rotation with respect to black hole (BH).

Supernova Neutrinos: Challenges and Opportunities

, 2018
Neutrinos are crucial ingredients for supernova explosions, and come to us bearing important particle physics and astrophysics information. Current and upcoming neutrino detectors are poised to detect these neutrinos, either as a diffuse background or ...

Analytical Description of the Distributions of Primary and Secondary Cosmogenic Particles

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this work, we present an analytical description of the energy distributions of primary and secondary cosmogenic particles on Earth in terms of parameters having clear physical meaning. A modified power law is assumed for energy distributions, incorporating terms such as energy loss/decay, which are effective at low energies, and a source term, which

KamLAND SENSITIVITY TO NEUTRINOS FROM PRE-SUPERNOVA STARS [PDF]

, 2017
In the late stages of nuclear burning for massive stars (M > 8 M⊙), the production of neutrino–antineutrino pairs through various processes becomes the dominant stellar cooling mechanism.

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Observing Supernova Neutrino Light Curves with Super-Kamiokande. V. Distance Estimation with Neutrinos

The Astrophysical Journal
Neutrinos are pivotal signals in multimessenger observations of supernovae (SNe). Recent advancements in the analysis method of supernova (SN) neutrinos, especially in quantitative analysis, have significantly broadened scientific possibilities.

Two Micron‐Size Dark Dimensions

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.
