Fast Radio Bursts

Fast Radio Bursts (FRBs) are few-millisecond bursts of radio waves coming from far outside the Milky Way.  Their origin is presently unknown.  Some FRBs are observed to exhibit repeat bursts, but it is presently unknown whether they represent a single class of object or multiple classes.  Recently there has been tremendous observational progress on understanding FRBs thanks to the CHIME Fast Radio Burst Project (CHIME/FRB).  In this talk I review what is known about FRBs, and describe the lastest CHIME/FRB results.

Fundamental Stellar Astrophysics in the Gaia Era: A New Understanding of Local Stellar Populations

We begin with an overview of the precision stellar astrophysics enabled by the confluence of Gaia parallaxes with large-scale photometric and spectroscopic surveys. We then give examples of the new understanding of local Galactic structure that this has enabled, including in particular the detailed history of canonical star-forming regions, and the discovery of “stellar strings” reflecting the local conditions of recent star formation.
