The Origin of the Iron-Rich Knot in Tycho's Supernova Remnant
Hiroya Yamaguchi, John P. Hughes, Carles Badenes +5
X-ray observations of supernova remnants (SNRs) allow us to investigate the chemical inhomogeneity of ejecta, offering unique insight into the nucleosynthesis in supernova explosio…
Supernova Remnants in the Local Group I: A model for the radio luminosity function and visibility times of supernova remnants
Sumit K. Sarbadhicary, Carles Badenes, Laura Chomiuk +2
Supernova remnants (SNRs) in Local Group galaxies offer unique insights into the origin of different types of supernovae. In order to take full advantage of these insights, one mus…
Nearby supernova host galaxies from the CALIFA Survey: II. SN environmental metallicity
L. Galbany, V. Stanishev, A. M. Mourão +16
The metallicity of a supernova (SN) progenitor, together with its mass, is one of the main parameters that rules their outcome. We present a metallicity study of 115 nearby SN host…
Gamma-Ray emission from SN2014J near maximum optical light
J. Isern, P. Jean, E. Bravo +17
The optical light curve of Type Ia supernovae (SNIa) is powered by thermalized gamma-rays produced by the decay of 56Ni and 56Co, the main radioactive isotopes synthesized by the t…
The Time-Domain Spectroscopic Survey: Understanding the Optically Variable Sky with SEQUELS in SDSS-III
John J. Ruan, Scott F. Anderson, Paul J. Green +27
The Time-Domain Spectroscopic Survey (TDSS) is an SDSS-IV eBOSS subproject primarily aimed at obtaining identification spectra of ~220,000 optically-variable objects systematically…
Neutronization During Carbon Simmering In Type Ia Supernova Progenitors
Héctor Martínez-Rodríguez, Anthony L. Piro, Josiah Schwab +1
When a Type Ia supernova (SN Ia) progenitor first ignites carbon in its core, it undergoes yr of convective burning prior to the onset of thermonuclear r…
