The Zwicky Transient Facility is a new robotic-observing program, in which a newly engineered 600-MP digital camera with a pioneeringly large field of view, 47~square degrees, will be installed into the 48-inch Samuel Oschin Telescope at the Palomar Observatory. The camera will generate $\sim 1$~petabyte of raw image data over three years of operations. In parallel related work, new hardware and software systems are being developed to process these data in real time and build a long-term archive for the processed products. The first public release of archived products is planned for early 2019, which will include processed images and astronomical-source catalogs of the northern sky in the $g$ and $r$ bands. Source catalogs based on two different methods will be generated for the archive: aperture photometry and point-spread-function fitting.

  1. On the origin of the environmental step: A BayeSN view of the ZTF SN Ia DR2

    astro-ph.CO 2026-05 unverdicted novelty 6.0

    BayeSN analysis of ZTF SN Ia DR2 data shows a persistent ~0.1 mag environmental step that is intrinsic to the supernovae, not explained by differing dust properties.

  2. LSST: from Science Drivers to Reference Design and Anticipated Data Products

    astro-ph 2008-05 accept novelty 6.0

    LSST will image 18,000 square degrees of sky about 800 times across six bands over 10 years to a coadded depth of r~27.5, producing a public database of 40 billion objects and 32 trillion observations.

  3. On the origin of the environmental step: A BayeSN view of the ZTF SN Ia DR2

    astro-ph.CO 2026-05 unverdicted novelty 5.0

    BayeSN analysis of ZTF Type Ia supernovae confirms a ~0.1 mag intrinsic environmental step in standardized brightness that is not explained by differences in dust extinction properties.
