Fantastic Beasts (& Where to Find Them): from Superluminous Supernovae to Calcium-rich Gap Transients

Ragnhild Lunnan (Caltech) - March 13, 2017 at 12:10 pm

In the past decade, the new generation of wide-field time-domain surveys have discovered several new classes of astronomical transients outside of the common classes of supernovae and novae. The physical origin of many of these rare transients are not well understood, and poses a challenge to our understanding of both stellar evolution and the explosion mechanisms of supernovae. In this talk, I will discuss some of the most intriguing "outlier" transients discovered in recent years, ranging from the most luminous supernovae to faint and fast "calcium-rich" transients, combining information from the explosions themselves and their host galaxy environments to shed light on their origins.

The seminar will be held in 131A Campbell Hall.
