Python tools for GW AGN follow-up
Project description
🛰️ gw_agn_watcher
Overview
gw_agn_watcher is a Python package for the automated crossmatching of gravitational-wave (GW) sky maps from the LIGO–Virgo–KAGRA (LVK) Collaboration with optical transient alerts and AGN catalogs.
It enables systematic searches for electromagnetic counterparts to compact binary mergers, with a particular focus on mergers that may occur in active galactic nuclei (AGN) disks.
Key Features
- 📡 Ingest LVK skymaps (
.fits, HEALPix format) - 🌌 Crossmatch ZTF alerts with AGN catalogs (e.g., Milliquas, Pan-STARRS)
- 🧠 Apply ML-based filters using ALeRCE classifiers, Pan-STARRS morphology, and Deep Real/Bogus scores
- 📅 Temporal and spatial filtering relative to the GW trigger time and sky localization
- 🎯 Host-galaxy association and ranking based on 2σ GW distance posteriors
- 🗺️ Visualization tools for probability maps, candidate locations, and sky coverage
- 🔧 Modular and extensible — suitable for ToO planning, multi-messenger analyses, and survey follow-up
