Rapid Reporting Resources

The General Coordinates Network

The General Coordinates Network (GCN) is a public collaboration platform run by NASA for the astronomy research community to share alerts and rapid communications about high-energy, multimessenger, and transient phenomena. GCN is the established platform for publishing discoveries and follow-up of gamma-ray bursts (GRBs), gravitational-wave (GW) compact binary mergers, and high-energy neutrinos. GCN distributes alerts between space- and ground-based observatories, physics experiments, and thousands of astronomers around the world.

The Gamma-ray Data Tools

The Gamma-ray Data Tools consist of an Application Programming Interface (API) for detctors that gather GBM like data. The fundamental purpose of the Data Tools is to allow general users to incorporate gamma-ray analysis into their scripts and workflows without having to sweat very many details. The Data Tools have a fairly high-level API layer allowing a user to read, reduce, and visualize GBM data with only a few lines of code. For expert users, and users who want fine control over various aspects of their analysis, the Data Tools exposes a lower-level API layer, which can also be used to generalize the GBM Data Tools to data from other like instruments.
