Title:  Exploring the Time-Domain Universe with the Young Supernova Experiment and the Dark Energy Science Collaboration

Abstract: The Young Supernova Experiment (YSE) is an optical time-domain survey running on the Pan-STARRS telescopes, producing thousands of well-calibrated griz light curves down to ~21.5 mag for time-domain events up to z ~ 0.2. I will describe the survey and highlight some key science results from YSE thus far. While YSE is a treasure trove of data in itself, it’s real strength is as a low-redshift counterpart to the Legacy Survey of Space and Time (LSST) on the upcoming Vera C. Rubin Observatory.  Unlike YSE, LSST will produce too many observations for humans to look through. Buried in these petabytes of Rubin pixels are rare and exotic sources like kilonovae but discovering them is now akin to looking for a needle amongst thousands of haystacks. To cope with the deluge of data, I will describe how we are employing artificial intelligence (AI) and building novel cyberinfrastructure on YSE to enable studies of the time-domain sky with LSST, and ultimately understand the nature of dark energy and the fate of the Universe.
