About:

Welcome to PEREGRINE! A public, open-source pipeline designed for targeted inference of gravitational wave signals from multiple source types.

Access:

Currently, PEREGRINE has two public branches:

  • cbc: Inferring source parameters of standard LVKC CBC sources.
  • overlapping: Inferring source parameters of overlapping or coincident gravitational wave detections in a 2G network.

Papers using PEREGRINE:

  • DOI Sequential simulation-based inference for gravitational wave signals (Bhardwaj, Alvey, Miller, Nissanke, Weniger)
  • DOI What to do when things get crowded? Scalable joint analysis of overlapping gravitational wave signals (Alvey, Bhardwaj, Nissanke, Weniger)

The algorithm:

PEREGRINE leverages the power of (Truncated Marginal) Neural Ratio Estimation (TMNRE) via the open-source package swyft.
