In this review we describe a transient type of gas discharge which is commonly called a
streamer discharge, as well as a few related phenomena in pulsed discharges. Streamers …

Abstract The Atmosphere‐Space Interactions Monitor (ASIM) was launched to the
International Space Station on 2 April 2018. The ASIM payload consists of two main …

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 …

We report on the spectral analysis of individual terrestrial gamma‐ray flashes (TGFs)
observed with the Fermi Gamma‐ray Burst Monitor (GBM). The large GBM TGF sample …

A 2D approach is used to simulate the properties of positive and negative streamers
emerging from a high-voltage electrode in a long (14 cm) air gap for standard pressure and …

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 investigate the emergence of space stems ahead of negative leaders. These are
luminous spots that appear ahead of an advancing leader mediating the leader's stepped …

X-ray and γ-ray emissions observed in lightning and long sparks are usually connected with
the bremsstrahlung of high-energy runaway electrons. Here, an alternative physical …

A 3D fluid model has been developed to simulate streamer discharges in unsteady airflow.
The model couples the drift–diffusion equation for charged particles, the Navier–Stokes …

During a winter thunderstorm on 24 November 2017, a strong burst of gamma rays with
energies up to∼ 10 MeV was detected coincident with a lightning discharge, by scintillation …
