SUPERNOVAE EXPLOSIONS THEORY AND COMPACT REMNANT OF SN 1987A
Hydrodynamics of massive star explosion within a non-spherical supernova model is presented. The explosive burning is computed in the He-core of a progenitor.

Abstract Patricia Berry’s interpretation of the Demeter/Persephone myth, and her concept of rape into consciousness, illuminate intrapsychic dynamics. However, this symbolic lens may inadvertently distance us from the devastating nature of literal rape—a reality the Homeric Hymn encapsulates.

EVIDENCE FOR PARTICLE ACCELERATION TO THE KNEE OF THE COSMIC RAY SPECTRUM IN TYCHO’S SUPERNOVA REMNANT [PDF]
Supernova remnants (SNRs) have long been assumed to be the source of cosmic rays (CRs) up to the “knee” of the CR spectrum at 1015 eV, accelerating particles to relativistic energies in their blast waves by the process of diffusive shock acceleration ...

An X-Ray Shell Reveals the Supernova Explosion for Galactic Microquasar SS 433
How black holes are formed remains an open and fundamental question in astrophysics. Despite theoretical predictions, it lacks observations to understand whether the black hole formation experiences a supernova explosion.

Electron acceleration in supernova remnants
Abstract Supernova remnants (SNRs) are believed to produce the majority of galactic cosmic rays (CRs). SNRs harbor non-relativistic collisionless shocks responsible for the acceleration of CRs via diffusive shock acceleration (DSA), in which particles gain their energy via repeated interactions with the shock front.

ABSTRACT Escalating concern regarding the impacts of reduced genetic diversity on the conservation of endangered species has spurred efforts to obtain chromosome‐level genomes through consortia such as the Vertebrate Genomes Project. However, assembling reference genomes for many threatened species remains challenging due to difficulties obtaining ...

ABSTRACT Population declines may have long‐term genetic consequences, including genetic erosion and inbreeding depression, which could affect species' evolutionary potential and increase their risk of extinction. Small populations are more vulnerable to genetic threats than common species, but even species with large populations can also be at risk of ...

OBSERVATION OF SUPERNOVA REMNANT IC 443 WITH THE FERMI LARGE AREA TELESCOPE [PDF]
We report observation of the supernova remnant (SNR) IC 443 (G189.1+3.0) with the Fermi Gamma-ray Space Telescope Large Area Telescope (LAT) in the energy band between 200 MeV and 50 GeV.
