A 14-year-old Mystery: The Peculiar Case of the Engine-driven SN 2012ap
Itai Sfaradi, Raffaella Margutti, Ryan Chornock +29
We present late-time ( d) optical (Keck), X-ray (Chandra and NuSTAR), and radio (VLA, ALMA, and the uGMRT) observations of the Type Ic-BL SN 2012ap. Previous studies of…
A Classification Scheme for X-ray Bright Type Ia Supernova Remnants Based on Their Circumstellar Interaction
Travis Court, Carles Badenes, Shiu-Hang Lee +2
The parameter space for mass loss in Type Ia supernova progenitors is large, with different progenitor scenarios favoring different mass loss regimes. Here we focus on the impact t…
Deciphering the explosion mechanism of Type-Ia SNe using their remnants I: general properties and a case study on Tycho's SNR
Soham Mandal, Núria Torres-AlbÃ, Carles Badenes +1
Type-Ia supernovae (SNe), or runaway thermonuclear explosions of white dwarfs (WDs), play a critical role in the chemical evolution of galaxies, and are important cosmological dist…
The Progenitor Systems of Classical Novae in M31
C. S. Abelson, Carles Badenes, Laura Chomiuk +4
We present the first characterization of the statistical relationship between a large sample of novae in M31 and their progenitor stellar populations in the form of a delay time di…
