Zwicky Transient Facility (ZTF)

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.

Catalina Real-time Transient Survey (CRTS)

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 --
