The Neil Gehrels Swift Observatory is a first-of-its-kind multi-wavelength observatory dedicated to the study of gamma-ray burst (GRB) science. Its three instruments work together to observe GRBs and afterglows in the gamma-ray, X-ray, ultraviolet, and optical wavebands. MAST serves as a secondary archive for the Ultraviolet Optical Telescope (UVOT).
