Data for Photodissociation of Some Small Molecular Ions Relevant for Astrochemistry and Laboratory Investigation

open access: yesData, 2022
The calculated photodissociation data of some small molecular ions have been reported. The cross-sections and spectral rate coefficients data have been studied using a quantum mechanical method. The plasma parameters, i.e., conditions, cover temperatures

Aerosol Shortwave Radiative Heating and Cooling by the 2017 and 2023 Chilean Wildfire Smoke Plumes

open access: yesGeophysical Research Letters, 2023
The aerosol shortwave, direct radiative effects of smoke plumes from Chilean wildfires in 2017 and 2023 were derived from satellite observations in both cloud‐free and cloud scenes.

Gamma-ray Bursts at the Highest Energies

open access: yesUniverse, 2021
Emission from Gamma-ray bursts is thought to be powered mainly by synchrotron radiation from energetic electrons. The same electrons might scatter these synchrotron seed photons to higher (>10 GeV) energies, building a distinct spectral component ...

Photodestruction of Diatomic Molecular Ions: Laboratory and Astrophysical Application

open access: yesMolecules, 2020
In this work, the processes of photodissociation of some diatomic molecular ions are investigated. The partial photodissociation cross-sections for the individual rovibrational states of the diatomic molecular ions, which involves alkali metals, as well ...

Exciton-Photon Interactions in Semiconductor Nanocrystals: Radiative Transitions, Non-Radiative Processes and Environment Effects

open access: yesApplied Sciences, 2021
In this review, we discuss several fundamental processes taking place in semiconductor nanocrystals (quantum dots (QDs)) when their electron subsystem interacts with electromagnetic (EM) radiation.

Electromagnetic Cascade Emission from Neutrino-coincident Tidal Disruption Events

open access: yesThe Astrophysical Journal, 2023
The potential association between Tidal Disruption Events and high-energy astrophysical neutrinos implies the acceleration of cosmic rays. These accelerated particles will initiate electromagnetic (EM) cascades spanning from keV to GeV energies via the ...
