Title: Extremes of Stripped Envelope Supernovae

Abstract:
The observational study of supernovae is undergoing a revolution brought 
about by wide-field synoptic surveys. The abundance of data offers 
insights into one of the biggest mysteries in the field; what are the 
ultimate fates of high-mass stars? Recent work in the field has 
suggested a lack of SNe associated with the most massive stars. In this 
talk, I will present the PhD work that I have been leading into 
stripped-envelope (SE) supernovae (SNe), which are thought to have 
high-mass origins. First, I will present the first systematic search for 
SE SNe that are associated with the highest mass stars, which found a 
largely unexplored population of extremely high-mass SE SNe. Next, I 
will move on to a rare sub-type of circumstellar interacting SE SNe 
called Type Ibn. Whose origin could also be linked to extremely 
high-mass stars.
