Constraints on VHE gamma-ray emission of flat spectrum radio quasars with the MAGIC telescopes
(Journal article; Peer reviewed, 2024)Flat spectrum radio quasars (FSRQs) constitute a class of jetted active galaxies characterized by a very luminous accretion disc, prominent and rapidly moving line-emitting cloud structures (broad-line region, BLR), and a ... -
U(1)-charged Dark Matter in three-Higgs-doublet models
(Journal article; Peer reviewed, 2024)We explore three-Higgs-doublet models that may accommodate scalar Dark Matter where the stability is based on an unbroken U(1)-based symmetry, rather than the familiar ℤ2 symmetry. Our aim is to classify all possible ways ... -
Hybrid quantum-classical polarizability model for single molecule biosensing
(Journal article; Peer reviewed, 2024)Optical whispering gallery mode biosensors are able to detect single molecules through effects of their polarizability. We address the factors that affect the polarizability of amino acids, which are the building blocks ... -
Reflection imaging with a helium zone plate microscope
(Journal article; Peer reviewed, 2024)Neutral helium atom microscopy is a novel microscopy technique which offers strictly surface-sensitive, nondestructive imaging. Several experiments have been published in recent years where images are obtained by scanning ... -
Cyanuric chloride as a linker towards the synthesis of covalent triazine polymers: a review
(Journal article; Peer reviewed, 2024)Covalent triazine polymers represent a promising class of materials composed of aromatic electron deficient 1,3,5-triazine repeating units. They are synthesized from different triazine monomers, where cyanuric chloride is ... -
Parameterizations for global thundercloud corona discharge distributions
(Journal article; Peer reviewed, 2024)Four parameterizations, distinguishing between land and ocean, have been developed to simulate global distributions of thundercloud streamer corona discharges (also known as Blue LUminous Events or BLUEs) mainly producing ... -
Towards the definition of a solar forcing dataset for CMIP7
(Journal article; Peer reviewed, 2024)The solar forcing prepared for Phase 6 of the Coupled Model Intercomparison Project (CMIP6) has been used extensively in climate model experiments and has been tested in various intercomparison studies. Recently, an ... -
The Ionospheric Leg of the Substorm Current Wedge: Combining Iridium and Ground Magnetometers
(Journal article; Peer reviewed, 2024)Utilizing magnetic field measurements made by the Iridium satellites and by ground magnetometers in North America we calculate the full ionospheric current system and investigate the substorm current wedge. The current ... -
Imaging of 3 bright terrestrial gamma-ray flashes by the atmosphere-space interactions monitor and their parent thunderstorms
(Journal article; Peer reviewed, 2024)The Atmosphere-Space Interactions Monitor (ASIM) on the International Space Station (ISS) includes an instrument designed to geolocate Terrestrial Gamma-ray Flashes (TGF) produced by thunderstorms. It does so with a coded ... -
Employing optical lightning data to identify lightning flashes associated to terrestrial gamma-ray flashes
(Journal article; Peer reviewed, 2024)Terrestrial gamma-ray flashes (TGFs) are bursts of energetic X- and gamma-rays emitted from thunderstorms. The Atmosphere-Space Interactions Monitor (ASIM) mounted onto the International Space Station (ISS) is dedicated ... -
Discerning TGF and Leader Current Pulse in ASIM Observation
(Journal article; Peer reviewed, 2024)Terrestrial gamma ray flash (TGF) observations made by the Atmosphere-Space Interaction Monitor (ASIM) have demonstrated that these TGFs are accompanied by a prominent optical pulse from a hot leader channel. It is hard ... -
