TL;DR: The first results of the high-cadence Galactic plane survey using the Zwicky Transient Facility (ZTF) were presented in this paper, which revealed the Galactic population of short-period variable stars, including short period binaries and stellar pulsators with periods less than a few hours.
Journal ArticleDOI
Unsupervised machine learning for transient discovery in deeper, wider, faster light curves
