Radio Detection of A Candidate Neutron Star Associated with Galactic Center Supernova Remnant Sagittarius A East
Jun-Hui Zhao, Mark R. Morris, W. M. Goss
We report the VLA detection of the radio counterpart of the X-ray object referred to as the "Cannonball", which has been proposed to be the remnant neutron star resulting from the…
First Simulations of Core- Collapse Supernovae to Supernova Remnants with SNSPH
Carola I. Ellinger, Gabriel Rockefeller, Christopher L. Fryer +2
We present the first 3-dimensional simulations following the evolution of supernova shocks from their inception in the stellar core through the development of a supernova remnant i…
X-ray observation of the shocked red supergiant wind of Cassiopeia A
Jae-Joon Lee, Sangwook Park, John P. Hughes +1
Cas A is a Galactic supernova remnant whose supernova explosion is observed to be of Type IIb from spectroscopy of its light echo. Having its SN type known, observational constrain…
A Super-Solar Metallicity for the Progenitor of Kepler's Supernova
Sangwook Park, Carles Badenes, Koji Mori +8
We have performed deep X-ray observations of the remnant of Kepler's supernova (SN 1604) as a Key Project of the Suzaku Observatory. Our main goal is to detect secondary Fe-peak el…
