Supernovae, the luminous explosions of stars, have been observed since antiquity.
However, various examples of superluminous supernovae (SLSNe; luminosities> 7× 1043 …

Core-collapse supernovae (CCSNe) mark the deaths of stars more massive than about eight
times the mass of the Sun and are intrinsically the most common kind of catastrophic cosmic …

We present the first extensive radio to γ-ray observations of a fast-rising blue optical
transient, AT 2018cow, over its first∼ 100 days. AT 2018cow rose over a few days to a peak …

We have entered an era of massive data sets in astronomy. In particular, the number of
supernova (SN) discoveries and classifications has substantially increased over the years …

Transient detection and flux measurement via image subtraction stand at the base of time
domain astronomy. Due to the varying seeing conditions, the image subtraction process is …

The explosive fate of massive Wolf–Rayet stars (WRSs) is a key open question in stellar
physics. An appealing option is that hydrogen-deficient WRSs are the progenitors of some …

This chapter describes the current classification scheme of supernovae (SNe). This scheme
has evolved over many decades and now includes numerous SN Types and sub-types …

JCW had long wanted to write a new monograph on supernovae. Despite an immense
explosion in the literature and many review articles, there had not been one since that of …

Time-domain science has undergone a revolution over the past decade, with tens of
thousands of new supernovae (SNe) discovered each year. However, several observational …

Stripped-envelope (SE) supernovae (SNe) include H-poor (Type IIb), H-free (Type Ib), and
He-free (Type Ic) events thought to be associated with the deaths of massive stars. The exact …
