Follow-up Observations

Past and current advances in the understanding of gamma-ray bursts (GRBs) have come from the cooperation of many telescopes observing different wavebands. While Swift has the capability of making multiwavelength observations of GRBs, continued multiwavelength observations of GRBs by other telescopes is not only anticipated but is invaluable.

Swift facilitates community-wide contributions to GRB science in two ways. First, Swift disseminates GRB positions as soon as they are available. This allows operators of other satellite and ground-based telescopes to schedule immediate observations when feasible. Second, if a GRB is discovered by another telescope, the coordinates can be uploaded to Swift so that it can perform rapid observations of these bursts.
