Leptonic and Hadronic Radiative Processes in Supermassive-Black-Hole Jets
Galaxies, 2020 Supermassive black holes lying in the center of galaxies can launch relativistic jets of plasma along their polar axis. The physics of black-hole jets is a very active research topic in astrophysics, owing to the fact that many questions remain open on ...

Initial-state parton shower kinematics for NLO event generators [PDF]
, 2007 We are developing a consistent method to combine tree-level event generators for hadron collision interactions with those including one additional QCD radiation from the initial-state partons, based on the limited leading-log (LLL) subtraction method ...

Boundary effects on radiative processes of two entangled atoms [PDF]
, 2016 We analyze radiative processes of a quantum system composed by two identical two-level atoms interacting with a massless scalar field prepared in the vacuum state in the presence of perfect reflecting flat mirrors. We consider that the atoms are prepared

Symmetric Atom–Atom and Ion–Atom Processes in Stellar Atmospheres
Atoms, 2017 We present the results of the influence of two groups of collisional processes (atom–atom and ion–atom) on the optical and kinetic properties of weakly ionized stellar atmospheres layers.

Collisional energy loss and the suppression of high $p_T$ hadrons [PDF]
, 2006 We calculate nuclear suppression factor ($R_{AA}$) for light hadrons by taking only the elastic processes and argue that in the measured $p_T$ domain of RHIC, collisional rather than the radiative processes is the dominant mechanism for partonic energy ...

Modelling transport processes in stellar radiative interiors
EPJ Web of Conferences, 2015 I report here on the different transport processes redistributing angular momentum and nuclides in stellar radiative interiors and on their modelling in stellar evolution codes.

NONRADIATIVE-TRANSITIONS IN SEMICONDUCTORS [PDF]
, 2002 Non-radiative transitions affect many aspects of semiconductor performance. Normally they reduce device efficiency by suppressing luminescence, creating defects, reducing carrier lifetimes, or enhancing diffusion during operation.

Radiative Transfer Modeling of Phytoplankton Fluorescence Quenching Processes
Remote Sensing, 2018 We report the first radiative transfer model that is able to simulate phytoplankton fluorescence with both photochemical and non-photochemical quenching included.

A Theoretical Study of Temperature-dependent Photodissociation Cross Sections and Rates for O2
The Astrophysical Journal Supplement Series, 2023 The photodissociation of O _2 is thought to play a vital role in blocking UV radiation in the Earth’s atmosphere and likely has great importance in characterizing exoplanetary atmospheres.

Can a Strong Radio Burst Escape the Magnetosphere of a Magnetar?
The Astrophysical Journal Letters, 2021 We examine the possibility that fast radio bursts (FRBs) are emitted inside the magnetosphere of a magnetar. On its way out, the radio wave must interact with a low-density e ^± plasma in the outer magnetosphere at radii R = 10 ^9 –10 ^10 cm.
