• #### Production of Terrestrial Gamma-Ray Flashes During the Early Stages of Lightning Flashes ﻿

(Journal article, 2022)
Terrestrial Gamma-ray Flashes (TGFs) are short emissions of high energy photons associated with thunderstorms. It has been known since the discovery of TGFs that they are associated with lightning, and several case studies ...

• #### Exploring solar-terrestrial interactions via multiple imaging observers ﻿

(Journal article; Peer reviewed, 2021)
How does solar wind energy flow through the Earth’s magnetosphere, how is it converted and distributed? is the question we want to address. We need to understand how geomagnetic storms and substorms start and grow, not ...
• #### A Simultaneous Observation of Lightning by ASIM, Colombia-Lightning Mapping Array, GLM, and ISS-LIS ﻿

(Journal article; Peer reviewed, 2021)
The Atmosphere-Space Interactions Monitor (ASIM) on the International Space Station (ISS) provides optical radiances and images of lightning flashes in several spectral bands. This work presents a lightning flash simultaneously ...
• #### Network community structure of substorms using SuperMAG magnetometers ﻿

(Journal article; Peer reviewed, 2021)
Geomagnetic substorms are a global magnetospheric reconfiguration, during which energy is abruptly transported to the ionosphere. Central to this are the auroral electrojets, large-scale ionospheric currents that are part ...
• #### Effective screening of medium-assisted van der Waals interactions between embedded particles ﻿

(Journal article; Peer reviewed, 2021)
The effect of an implicit medium on dispersive interactions of particle pairs is discussed, and simple expressions for the correction relative to vacuum are derived. We show that a single point Gauss quadrature leads to ...
• #### Spectral Observations of Optical Emissions Associated With Terrestrial Gamma-Ray Flashes ﻿

(Journal article; Peer reviewed, 2021)
The Atmosphere-Space Interactions Monitor measures Terrestrial Gamma-Ray Flashes (TGFs) simultaneously with optical emissions from associated lightning activity. We analyzed optical measurements at 180–230, 337, and 777.4 ...
• #### Time evolution of storms producing terrestrial gamma-ray flashes using era5 reanalysis data, gps, lightning and geo-stationary satellite observations ﻿

(Journal article; Peer reviewed, 2021)
In this article, we report the first investigation over time of the atmospheric conditions around terrestrial gamma-ray flash (TGF) occurrences, using GPS sensors in combination with geostationary satellite observations ...
• #### Magnetospheric Flux Throughput in the Dungey Cycle: Identification of Convection State During 2010 ﻿

(Journal article; Peer reviewed, 2021)
We quantify the contributions of different convection states to the magnetic flux throughput of the magnetosphere during 2010. To do this we provide a continuous classification of convection state for the duration of 2010 ...
• #### Low-energy probes of no-scale SU(5) super-GUTs ﻿

(Journal article; Peer reviewed, 2021)
We explore the possible values of the $\mu \rightarrow e \gamma$ branching ratio, $\text {BR}(\mu \rightarrow e\gamma )$, and the electron dipole moment (eEDM), $d_e$, in no-scale SU(5) super-GUT models with the ...
• #### Deep learning jet modifications in heavy-ion collisions ﻿

(Journal article; Peer reviewed, 2021)
Jet interactions in a hot QCD medium created in heavy-ion collisions are conventionally assessed by measuring the modification of the distributions of jet observables with respect to the proton-proton baseline. However, ...
• #### Bifurcated Current Sheet Observed on the Boundary of Kelvin-Helmholtz Vortices ﻿

(Journal article; Peer reviewed, 2021)
On May 5, 2017 MMS observed a bifurcated current sheet at the boundary of Kelvin-Helmholtz vortices (KHVs) developed on the dawnside tailward magnetopause. We use the event to enhance our understanding of the formation and ...
• #### Large area microwave plasma CVD of diamond using composite right/left-handed materials ﻿

(Journal article; Peer reviewed, 2021)
Diamond growth at low temperatures (≤400 °C) and over large areas is attractive for materials, which are sensitive to high temperatures and require good electronic, chemical or surface tribological properties. Resonant-cavity ...
• #### Wilson line correlators beyond the large-Nc ﻿

(Journal article; Peer reviewed, 2021)
We study hard 1 → 2 final-state parton splittings in the medium, and put special emphasis on calculating the Wilson line correlators that appear in these calculations. As partons go through the medium their color continuously ...

(Journal article; Peer reviewed, 2021)
The event-by-event correlations between three flow amplitudes are measured for the first time in Pb-Pb collisions, using higher-order symmetric cumulants. We find that different three-harmonic correlations develop during ...
