We report the discovery of GRB 221009A, the highest flux gamma-ray burst (GRB) ever
observed by the Fermi Gamma-ray Burst Monitor (Fermi-GBM). This GRB has continuous …

Terrestrial gamma-ray flashes (TGFs) are high-energy emissions in thunderstorms that were
discovered first by satellite-based and then by ground-based gamma-ray detectors with …

We have designed, developed, and deployed a distributed sensor network to observe high-
energy ionizing radiation, primarily gamma rays, from winter thunderclouds and lightning in …

In this paper we report the first close, high‐resolution observations of downward‐directed
terrestrial gamma‐ray flashes (TGFs) detected by the large‐area Telescope Array cosmic …

Two types of high-energy events have been detected from thunderstorms. One is “terrestrial
gamma-ray flashes”(TGFs), sub-millisecond emissions coinciding with lightning discharges …

Bursts of gamma ray showers have been observed in coincidence with downward
propagating negative leaders in lightning flashes by the Telescope Array Surface Detector …

In 2015, the Gamma-Ray Observation of Winter Thunderstorms (GROWTH) collaboration
launched a mapping observation campaign for high-energy atmospheric phenomena …

We present the first Fermi Space Telescope Gamma Ray Burst Monitor (GBM) catalog of
4,144 terrestrial gamma ray flashes (TGFs), detected since launch in 11 July 2008 through …

Following a lightning strike to a wind turbine in Japan, we have observed a large burst of
neutrons lasting 100 ms with a ground fluence of~ 1,000 n cm− 2, thousands of times greater …

ABSTRACT Peaking at 3.7 mag on 2020 July 11, YZ Ret was the second-brightest nova of
the decade. The nova's moderate proximity (2.7 kpc, from Gaia) provided an opportunity to …
