Latest Status Update (Jan 24, 2022):
Due to zeolite particle contamination, the ZTF camera will be returned to campus again. Cleaning procedures are expected to keep us off regular science observations for another 3 weeks.

What is ZTF?

The Zwicky Transient Facility (ZTF) is a public-private partnership aimed at a systematic study of the optical night sky. Using an extremely wide-field of view camera, ZTF scans the entire Northern sky every two days. The resulting large area survey will enable the astronomical community to pursue a broad range of time-domain science ranging from near-Earth asteroids to the study of distant superluminous supernovae. ZTF is funded in equal part by the US National Science Foundation and an international consortium of universities and institutions.

Extreme Field of View

ZTF employs a custom-built mosaic CCD camera which utilizes the entire focal plane (~ 47 sq deg) of the P48 telescope at Palomar, providing the largest instantaneous field-of-view of any camera on a telescope of aperture greater than half a meter.

Unique survey

ZTF scans the northern sky at high cadance (~2 days) to produce a comprehensive, multi-filter survey. ZTF delivers bi-monthly public data releases of high quality and reliable data products to enable time-domain science.
