Stars more massive than about 8 times the mass of the Sun end their lives in
cataclysmic explosions: supernovae and gamma-ray bursts. In recent years targeted
and blind transient surveys have expanded the range of potential outcomes, including
potentially non-destructive eruptions on the path to the eventual explosion and
highly-luminous events that may require a new range of progenitor...

In the last fifteen years, searches for the progenitors of core-collapse supernovae
in archival Hubble Space Telescope images have yielded progenitor candidates for ~10
nearby supernovae, and upper limits on the luminosity and mass for a further ~20. In
this talk, I discuss recent results from ongoing progenitor searches. In particular,
I focus on some of the open questions in progenitor...

A number of supernovae has been discovered in recent times
showing weird observed
properties. A few of them are extremely sub-luminous, others
are among the brightest
stellar explosions ever observed. In this review I present
photometric and
spectroscopic data of some of the most astonishing unusual
transients, and outline
what we currently know on the nature of their progenitor stars.

I will make a quick review of the connection between Supernovae
and Gamma-Ray Bursts, from an observers perspective. I plan to run
through the history of GRBs with a special eye to the SN associations, and
try to include also some of the more recent issues and developments.

Recent progress in observations have allowed us to now find an
overwhelming collection of observational supernova data including a
wealth of different classes and marvelous detail in part. But how do
they connect with our understanding of the underlying engine, and what
stars are responsible for each of them? Theoretical models, on the
other hand, also provides a wide variety of model,...

The theoretical prediction that stars that develop heavy oxygen cores will become
pair-unstable and explode has been made many decades ago. Yet, for many years, no
examples of such explosions were found, and it was often conjectured that stars
massive enough to explode in this manner may only exist at very high redshifts
(population III stars). In recent years several luminous supernova...
