Developing the O4 PyGRB Workflow

In 2017, the LIGO-Virgo collaboration (LVC) discovered a gravitational wave, GW170817, that was coincident with a gamma ray burst, GRB170817A. This joint detection was a major milestone in multi-messenger astronomy, which is the collaboration between different fields of astronomers. It showed that binary neutron star mergers can generate both gravitational and electromagnetic radiation, and now astronomers are looking to find more joint events. One of the LVK analysis pipelines to do this, called PyGRB, is being upgraded. The current code has become outdated, with many of its dependencies no longer supported. The pipeline is being rewritten to be fully integrated into PyCBC, an open source repository with many useful features for gravitational wave searches. This upgrade will improve the speed, stability, and accessibility of the PyGRB pipeline. The purpose of this project is to continue the development of the new pipeline and compare it to its predecessor.
