Low-Latency Algorithm for Multi-messenger Astrophysics (LLAMA)’s Documentation

LLAMA is a reliable and flexible multi-messenger astrophysics framework and search pipeline. It identifies astrophysical signals by combining observations from multiple types of astrophysical messengers and can either be run in online mode as a self-contained low-latency pipeline or in offline mode for post-hoc analyses. It was first used during Advanced LIGO’s second observing run (O2) for the joint online LIGO/Virgo/IceCube Gravitational Wave/High-Energy Neutrino (GWHEN) search (hence the historical name of gwhen for many of the modules).

LLAMA’s search alorithm has been upgraded to run during LIGO’s third observing run (O3).
