Abstract:
We describe Glowbug, a gamma-ray telescope for bursts and other transients in the 30 keV to 2 MeV band. It was recently funded by the NASA Astrophysics Research and Analysis program, with an expected launch in the early 2020s. Similar in concept to the Fermi Gamma Burst Monitor (GBM) and with similar sensitivity, Glowbug will join and enhance future networks of high-energy telescopes to increase sky coverage and detection efficiency for cosmic Gamma Ray Bursts. From its platform on the International Space Station, Glowbug will also have significant sensitivity to Terrestrial Gamma-ray Flashes (TGFs), the sub-millisecond bursts of gamma rays and relativistic electrons from thunderstorms. We describe the instrument and its capabilities to study these energetic transients.
