Generation of Cosmic rays in Historical Supernova Remnants [PDF]
EPJ Web of Conferences, 2013 We present the results of observations of two types of Galactic supernova remnants with the SHALON mirror Cherenkov telescope of Tien-Shan high-mountain Observatory: the shell-type supernova remnants Tycho, Cas A and IC 443; plerions Crab Nebula, 3c58(SN1181) and Geminga (probably plerion).

Magnetic Field Generation by Charge Exchange in a Supernova Remnant in the Early Universe [PDF]
The Astrophysical Journal, 2021 Abstract We present new-generation mechanisms of magnetic fields in supernova remnant shocks propagating to partially ionized plasmas in the early universe. Upstream plasmas are dissipated at the collisionless shock, but hydrogen atoms are not dissipated because they do not interact with electromagnetic fields.

THE GENERAL RELATIVISTIC INSTABILITY SUPERNOVA OF A SUPERMASSIVE POPULATION III STAR [PDF]
The Astrophysical Journal, 2014 The formation of supermassive Population III stars with masses $\gtrsim$ 10,000 Msun in primeval galaxies in strong UV backgrounds at $z \sim$ 15 may be the most viable pathway to the formation of supermassive black holes by $z \sim$ 7. Most of these stars are expected to live for short times and then directly collapse to black holes, with little or no

Latest supernova data in the framework of the generalized Chaplygin gas model [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We use the most recent Type-Ia Supernova data in order to study the dark energy - dark matter unification approach in the context of the Generalized Chaplygin Gas (GCG) model. Rather surprisingly, we find that data allow models with $α> 1$. We have studied how the GCG adjusts flat and non-flat models, and our results show that GCG is consistent with

Generalized Kompaneets formalism for inelastic neutrino-nucleon scattering in supernova simulations [PDF]
Physical Review D, 2020 Based on the Kompaneets approximation, we develop a robust methodology to calculate spectral redistribution via inelastic neutrino-nucleon scattering in the context of core-collapse supernova simulations. The resulting equations conserve lepton number to machine precision and scale linearly, not quadratically, with number of energy groups.

Physical Review D, 2019 We optimize the third-generation gravitational-wave detector to maximize the range to detect core-collapse supernovae. Based on three-dimensional simulations for core-collapse and the corresponding gravitational-wave waveform emitted, the corresponding detection range for these waveforms is limited to within our galaxy even in the era of third ...

Advanced Science, EarlyView.The C3‐symmetric conjugate TASe, which integrates benzoselenadiazole, alanine, and acylhydrazone modules, self‐assembles into a chalcogen‐/hydrogen‐bonded porous framework in the solid state and uniform chiral nanospheres in aqueous media. These assemblies protect cardiomyocytes from doxorubicin‐induced oxidative injury by scavenging intracellular ...

Photo‐Induced Stepwise Liquid Crystal Phase Transition Enabled by Hydrazone Photoswitch
Advanced Science, EarlyView.A judiciously designed bistable hydrazone photoswitch enables a photo‐induced stepwise “order‐disorder” phase transition in liquid crystals. The linear‐to‐bent isomerization disrupts molecular packing, allowing precise tuning of phase transition temperatures.

Patient‐Derived Fibroblasts as a Clinically Relevant Model of Kearns–Sayre Syndrome
Annals of Neurology, EarlyView.Objective Kearns–Sayre syndrome (KSS) is characterized by single large‐scale mitochondrial DNA deletions and by severe early‐onset clinical manifestations with neurological involvement. Reliable disease models, as well as validated biomarkers or effective treatments, are lacking.
