▪ Abstract The temporal evolution of the optical spectra of various types of supernovae (SNe)
is illustrated, in part to aid observers classifying supernova candidates. Type II SNe are …

Knowledge of the progenitors of core-collapse supernovae is a fundamental component in
understanding the explosions. The recent progress in finding such stars is reviewed. The …

The radio emission from supernovae has been modeled as synchrotron emission from the
interaction between the supernova and a presupernova stellar wind. The emission shows a …

▪ Abstract Study of radio supernovae over the past 20 years includes two dozen detected
objects and more than 100 upper limits. From this work it is possible to identify classes of …

We present the PMAS/PPak Integral-field Supernova hosts COmpilation (PISCO), which
comprises integral field spectroscopy (IFS) of 232 supernova (SN) host galaxies that hosted …

We present a detailed study of line structure in early to late-time spectra of supernova (SN)
1993J. Spectra during the nebular phase, but within the first two years after explosion …

We present and analyse spectra of the Type IIn supernova (SN) 1994W obtained between
18 and 203 d after explosion. During the luminous phase (first 100 d) the line profiles are …

To place core-collapse supernovae (SNe) in context with the evolution of massive stars, it is
necessary to determine their stellar origins. I describe the direct identification of SN …

We present optical spectra and photometry sampling the first 6 months after discovery of
supernova (SN) 1999gi in NGC 3184. SN 1999gi is shown to be a Type II-plateau event with …

As part of a larger completed Hubble Space Telescope (HST) Snapshot program, we
observed the sites of six nearby core-collapse supernovae (SNe) at high spatial resolution …
