Final Moments. II. Observational Properties and Physical Modeling of Circumstellar-material-interacting Type II Supernovae

The Astrophysical Journal
We present ultraviolet/optical/near-infrared observations and modeling of Type II supernovae (SNe II) whose early time ( δ t < 2 days) spectra show transient, narrow emission lines from shock ionization of confined ( r < 10 ^15 cm) circumstellar material

Supernova Siblings and Spectroscopic Host Galaxy Properties

The Astrophysical Journal
Over the past century, supernova (SN) searches have detected multiple supernovae (SNe) in hundreds of individual galaxies. So-called SN siblings discovered in the same galaxy present an opportunity to constrain the dependence of the properties of SNe on ...
