MHD Interaction of Pulsar Wind Nebulae with SNRs and the ISM
, 2005 In the late 1960s the discovery of the Crab pulsar in its associated supernova remnant, launched a new field in supernova remnant research: the study of pulsar-driven or plerionic supernova remnants.

Supernova Cooling in a Dark Matter Smog [PDF]
, 2014 A light hidden gauge boson with kinetic mixing with the usual photon is a popular setup in theories of dark matter. The supernova cooling via radiating the hidden boson is known to put an important constraint on the mixing.

A simple approach to the supernova progenitor–explosion connection [PDF]
, 2016 We present a new approach to understand the landscape of supernova explosion energies, ejected nickel masses, and neutron star birth masses. In contrast to other recent parametric approaches, our model predicts the properties of neutrino-driven ...

Nachtsicht ins All mit dem bloßen Auge: Sag mir, wie weit die Sterne steh'n
Physik in unserer Zeit, EarlyView.Beim Blick in den Nachthimmel sehen wir ohne optische Hilfsmittel und abhängig von der lokalen Lichtverschmutzung viele Hundert bis maximal einige Tausend Sterne und auch einige Galaxien. Aber wie weit sind diese von uns entfernt? Und bis zu welchen maximalen Entfernungen können wir Objekte im Weltall mit dem bloßen Auge wahrnehmen?

What can be learned from a future supernova neutrino detection [PDF]
, 2017 This year marks the thirtieth anniversary of the only supernova from which we have detected neutrinos - SN 1987A. The twenty or so neutrinos that were detected were mined to great depth in order to determine the events that occurred in the explosion and ...

Supernova lightCURVE POPulation Synthesis I: Including interacting binaries is key to understanding the diversity of type II supernova lightcurves [PDF]
Publications Astronomical Society of Australia, 2018 We present results of a supernova lightcurve population synthesis, predicting the range of possible supernova lightcurves arising from a population of progenitor stars that include interacting binary systems. We show that the known diversity of supernova

Propellants, Explosives, Pyrotechnics, EarlyView.A new copper compound based on the trinitropyrazolate (TNP−) ligand ammonium copper(II) (tetrakis)trinitropyrazolate [(NH4+)2CuII(TNP−)4] has been prepared and structurally characterized, which displays different thermo‐chemical behaviour and sensitivity properties from the parent compound ammonium 3,4,5‐trinitropyrazolate. ABSTRACT The urgent need for

An outburst from a massive star 40 days before a supernova explosion [PDF]
, 2013 Various lines of evidence suggest that very massive stars experience extreme mass-loss episodes shortly before they explode as a supernova. Interestingly, several models predict such pre-explosion outbursts. Establishing a causal connection between these

Small Methods, EarlyView.This study introduces a single‐molecule strategy using activity‐based probes (ABPs) to sensitively detect accessible enzymes in complex biological systems. The approach successfully visualizes the active forms of PSA and granzyme B, demonstrating its utility for probing protease activity states with high selectivity and sensitivity at the molecular ...

Neutrino flavor instabilities in a time-dependent supernova model
Physics Letters B, 2015 A dense neutrino medium such as that inside a core-collapse supernova can experience collective flavor conversion or oscillations because of the neutral-current weak interaction among the neutrinos.
