Evolutionary Applications, Volume 17, Issue 10, October 2024.ABSTRACT Biological invasions have caused the loss of freshwater biodiversity worldwide. The interplay between adaptive responses and demographic characteristics of populations impacted by invasions is expected to be important for their resilience, but the interaction between these factors is poorly understood. The freshwater gastropod Amnicola limosus

Archival Search for X-ray Emission From Type Ib/c Supernovae [PDF]
, 2023 We present results from an ongoing archival search for X-ray emission from all known Type Ib/c supernovae using data from the Chandra X-ray Observatory. For each supernova, we search all possible observations to find those with coverage in X-rays.

Evolutionary Applications, Volume 17, Issue 9, September 2024.ABSTRACT Anthropogenic impact has transitioned from threatening already rare species to causing significant declines in once numerous organisms. Long‐tailed duck (Clangula hyemalis) and velvet scoter (Melanitta fusca) were once important quarry sea duck species in NW Europe, but recent declines resulted in their reclassification as vulnerable on the ...

Late-time Optical and X-Ray Emission Evolution of the Oxygen-rich SN 1996cr
The Astrophysical JournalWhen the ejecta of a supernova (SN) interact with the progenitor star's circumstellar environment, a strong shock is driven back into the ejecta, causing the material to become bright optically and in X-rays.

Type Ib/Ic Supernovae: Effect of Nickel Mixing on the Early-time Color Evolution and Implications for the Progenitors [PDF]
, 2019 We investigate the effect of mixing of radioactive nickel (Ni-56) on the early-time color evolution of Type Ib and Ic supernovae (SNe Ib/Ic) using multigroup radiation hydrodynamics simulations.

The connection between gamma-ray bursts and supernovae Ib/c [PDF]
, 2007 Context: It has been established that Gamma-Ray Bursts (GRBs) are connected to Supernovae (SNe) explosions of type Ib/c. Aims: We intend to test whether the hypothesis of type Ib/c SNe from different massive progenitors can reproduce the local GRB rate ...

Acta Crystallographica Section B, Volume 80, Issue 4, Page 347-359, August 2024.The reactions of Cu(ClO4)2·6H2O and L′H in a variety of solvents have provided access to 12 solvatomorphs of the general formula [Cu(ClO4)2(LH)4]·x(solvent); the effect of the solvents on the packing of the complexes is critically discussed.In the course of an investigation of the supramolecular behaviour of copper(II) complexes with the 5 ...

Magnetorotational Explosions of Core-Collapse Supernovae
Acta Polytechnica CTU Proceedings, 2014 Core-collapse supernovae are accompanied by formation of neutron stars. The gravitation energy is transformed into the energy of the explosion, observed as SN II, SN Ib,c type supernovae.

The Astrophysical JournalWe present multiband ATLAS and ZTF photometry for SN 2019tsf, a Type Ib stripped-envelope supernova (SESN). The slow spectral evolution could be associated with an uncommon explosion mechanism specific to this SN.
