The Zwicky Transient Facility (ZTF) is a 47 square degree field of view time-domain survey from the Samuel Oschin 48-inch Schmidt telescope at Palomar Observatory in California. DR2 was released recently (Dec 2019) and boasts of 100 billion source detections in g/r/i filters combined. I lead the machine learning (ML) for the survey, and the team works on various classification aspects e.g. separating real-bogus sources, identifying streaking asteroids, pigeon holing sources in to their subclasses using advanced statistical and computational methods.

The Catalina Sky Survey (CSS) NEO project uses three dedicated telescopes to cover thirty three thousand square degrees (now two in Arizona). The Catalina Real-Time Transient Survey (CRTS) utilized the CSS data to search for rare and interesting transients and variables. Currently the transients are not actively screened. I worked on classification of transients as well as building some initial infrastructure. keyword crts keyword catalina --
