Radio-continuum observations of small, radially polarised Supernova Remnant J0519-6902 in the large Magellanic cloud [PDF]
Serbian Astronomical Journal, 2012 We report on new Australian Telescope Compact Array (ATCA) observations of SNR J0519-6902. The Supernova Remnant (SNR) is small in size (~8 pc) and exhibits a typical SNR spectrum with α = -0.53±0.07, with steeper spectral indices towards the ...

Global Deceleration and Inward Movements of X-Ray Knots and Rims of RCW 103
The Astrophysical Journal, 2023 The kinematics of shocks, ejecta knots, and the compact remnant of a supernova remnant give insights into the nature of the progenitor and the surrounding environment.

A Python Calculator for Supernova Remnant Evolution [PDF]
, 2017 A freely available Python code for modeling supernova remnant (SNR) evolution has been created. This software is intended for two purposes: to understand SNR evolution and to use in modeling observations of SNR for obtaining good estimates of SNR ...

A solar-type star polluted by calcium-rich supernova ejecta inside the supernova remnant RCW 86 [PDF]
Nature Astronomy, 2017 When a massive star in a binary system explodes as a supernova, its companion star may be polluted with heavy elements from the supernova ejecta. Such pollution has been detected in a handful of post-supernova binaries1, but none of them is associated ...

The Astrophysical Journal, 2023 The Cassiopeia A supernova remnant has a complex structure, manifesting the multidimensional nature of core-collapse supernova explosions. To further understand this, we carried out near-infrared multiobject spectroscopy on the ejecta knots located in ...

Galactic Supernova Remnant Candidates Discovered by THOR [PDF]
, 2017 Context. There is a considerable deficiency in the number of known supernova remnants (SNRs) in the Galaxy compared to that expected. This deficiency is thought to be caused by a lack of sensitive radio continuum data.

THE IMPACT OF A SUPERNOVA REMNANT ON FAST RADIO BURSTS [PDF]
, 2016 Fast radio bursts (FRBs) are millisecond bursts of radio radiation whose progenitors, so far, remain mysterious. Nevertheless, the timescales and energetics of these events have lead to many theories associating FRBs with young neutron stars (NSs ...

Gamma-ray Observations of Tycho’s Supernova Remnant with VERITAS and Fermi [PDF]
, 2017 High-energy gamma-ray emission from supernova remnants (SNRs) has provided a unique perspective for studies of Galactic cosmic-ray acceleration. Tycho’s SNR is a particularly good target because it is a young, type Ia SNR that has been well-studied over ...

iMeta, Volume 1, Issue 4, December 2022., 2022 We developed a tool to get high‐quality genomes with high taxonomic resolution by combining the cobarcoding information with public references. Compared with the conventional combination strategies, our pipeline generated a large number of high‐quality genomes for the human microbial cobarcoding data sets. Abstract Metagenomic evidence of great genetic

First Observations of SN 1604 (Kepler’s Supernova)
Universe, 2021 A supernova close enough to the Earth is a spectacular event: it can appear as a “new star” as luminous as Venus, or even more, visible for several days.
