Retrain Parsnip for ZTF

Low-latency hostless transient triage pipeline for TNS reporting and follow-up prioritization.

Browser-based orchestration layer for the Nutanix ZeroTouch Framework. Replaces manual YAML editing with RBAC, scheduled execution, approval gates, drift detection, and live terminal streaming.

Provides a forced photometry pipeline for ZTF based on ztfquery and ztflc

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.

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 to optical, X-ray and radio data with nested sampling, validated on public ZTF images of GRB 221009A and GRB 210204A.

Research workflow for identifying weak AGN candidates using DESI spectroscopy and ZTF optical variability.

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

Original observations and one-command reproduction of a 117.4-minute white-dwarf cycle and a 3.431-day candidate.

Analysis of Zwicky Transient Facility (ZTF) transient alerts around the Andromeda Galaxy (M31) — a 2020 astronomy project.

Application-grade, multimodal AI pipeline for real-time astronomical alert streams (ZTF & LSST). Combines a physics-informed continuous-time Transformer, C8 rotation-equivariant CNN stamp encoder and Bayesian Monte Carlo Dropout epistemic uncertainty estimation for sub-millisecond inference and high-throughput streaming.

Create a gif of stamps given an object id of ZTF

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.
