The Supernova – Supernova Remnant Connection [PDF]
, 2016 Many aspects of the progenitor systems, environments, and explosion dynamics of the various subtypes of supernovae are difficult to investigate at extragalactic distances where they are observed as unresolved sources. Alternatively, young supernova remnants in our own galaxy and in the Large and Small Magellanic Clouds offer opportunities to resolve ...

Supernova 1604, Kepler’s Supernova, and Its Remnant [PDF]
, 2016 Supernova 1604 is the last Galactic supernova for which historical records exist. Johannes Kepler's name is attached to it, as he published a detailed account of the observations made by himself and European colleagues. Supernova 1604 was very likely a Type Ia supernova, which exploded 350 pc to 750 pc above the Galactic plane.

The fully developed remnant of a neutrino-driven supernova [PDF]
Astronomy & Astrophysics, 2020 Context. The remnants of core-collapse supernovae (SNe) are probes of the physical processes associated with their parent SNe. Aims. Here we aim to explore to which extent the remnant keeps memory of the asymmetries that develop stochastically in the ...

From Supernova to Supernova Remnant: The Three-dimensional Imprint of a Thermonuclear Explosion [PDF]
Astrophysical Journal, 2019 Recent progress in three-dimensional modeling of supernovae (SNe) has shown the importance of asymmetries in the explosion. This calls for a reconsideration of the modeling of the subsequent phase, the supernova remnant (SNR), which has commonly relied ...

Multifrequency observations of one of the largest supernova remnants in the local group of galaxies, LMC - SNR J0450-709 [PDF]
Serbian Astronomical Journal, 2009 We present the results of new Australia Telescope Compact Array (ATCA) observations of one of the largest supernova remnants, SNR J0450-709, in the Local Group of galaxies.

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 ...

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 ...

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.

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.
