The Search for Supernova-produced Radionuclides in Terrestrial Deep-sea Archives [PDF]
, 2012 An enhanced concentration of 60Fe was found in a deep ocean's crust in 2004 in a layer corresponding to an age of ~2 Myr. The confirmation of this signal in terrestrial archives as supernova-induced and detection of other supernova-produced radionuclides

Supernovae and cosmology [PDF]
General Relativity and Gravitation, 2007 The extreme luminosity and their fairly unique temporal behaviour have made supernovae a superb tool to measure distances in the universe. As complex astrophysical events they provide interesting insights into explosion physics, explosive nucleosynthesis, hydrodynamics of the explosion and radiation transport.

Reduction of CO2 and Related Compounds with a Low‐Valent CaI Synthon
ChemistryEurope, EarlyView.The reduction of CO2, CS2, or carbodiimide with a CaI synthon results in formation of calcium complexes with CO32−, CS22− or C–C coupled carbodiimide dianions. Differences between reduction of these reagents with the CaI synthon and established MgI complexes are discussed. Combined experimental and computational investigations give insight in the first

Core-collapse supernova neutrinos and neutrino properties
, 2008 Core-collapse supernovae are powerful neutrino sources. The observation of a future (extra-)galactic supernova explosion or of the relic supernova neutrinos might provide important information on the supernova dynamics, on the supernova formation rate ...

The consequences of a nearby supernova on the early Solar System [PDF]
, 2018 If the Sun was born in a relatively compact open cluster, it is quite likely that a massive (10MSun) star was nearby when it exploded in a supernova. The repercussions of a supernova can be rather profound, and the current Solar System may still bear the

Symposium - International Astronomical Union, 1982 Three supernovae have so far been detected in the radio range shortly after their optical outbursts. All are Type IIs. A fourth supernova, a Type I, is being monitored for radio emission but, at an age of approximately one year, has not yet been detected.

Fundamental physics studies in time domain and multi-messenger astronomy
Frontiers in Astronomy and Space SciencesThe era of ime domain and multi-messenger astronomy is not only leading to the development of a much broader set of detectors and instruments for astrophysical observations, but is also providing the means for astronomy to tie directly to cutting-edge ...

Ejection of Supernova-Enriched Gas From Dwarf Disk Galaxies [PDF]
Astrophys.J. 617 (2004) 1077-1090, 2004 We examine the efficiency with which supernova-enriched gas may be ejected from dwarf disk galaxies, using a methodology previously employed to study the self-enrichment efficiency of dwarf spheroidal systems. Unlike previous studies that focused on highly concentrated starbursts, in the current work we consider discrete supernova events spread ...

Photoinduced Hydrogen Evolution Catalyzed by Co(II) Complexes of N5‐Donor Ligands
Chemistry – A European Journal, EarlyView.Cobalt(II) complexes of three related pentadentate ligands have been investigated as photoelectrochemical catalysts for proton reduction/hydrogen gas evolution in the presence of ruthenium, iridium, or copper‐based photosensitizers. Potential mechanisms for hydrogen evolution have been investigated by time‐resolved transient absorption spectroscopy and
