Bulk Zwicky Transient Facility Frames Downloader for making astrophotography with ZTF data

Watches public sky-survey data for objects whose brightness does not fit the simple models, and builds a reviewable case file for each one. Python pipeline plus a React analyst workstation.

A python library to streamline requesting Zwicky Transient Facility (ZTF) forced photometry.

From raw telescope frames to gamma-ray burst physics: image subtraction, PSF photometry, multi-instrument light curves through real filter curves, power-law and afterglowpy jet fits, validated on public ZTF images of GRB 221009A and GRB 210204A.

Feature-based classifier that reproduces the human vetting decisions of the ZTF O3 gravitational-wave follow-up campaign, plus a catalogue of where it fails on sparse photometry.
