Nonmonotone spectral projected gradient methods on convex sets
(Siam PublicationsPhiladelphiaEUA, 2000)
Long-Term Monitoring of the Dynamics and Particle Acceleration of Knots in the Jet of Centaurus A
(2010)
We present new and archival multi-frequency radio and X-ray data for Centaurus A obtained over almost 20 years at the Very Large Array and with Chandra, with which we measure the X-ray and radio spectral indices of jet ...
Influence of the uncertainty in the soil-rock spectral ratios in the definition of uniform hazard spectra at surface level
(IMPERIAL COLLEGE PRESSUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2006-01-01)
Based on traditionally accepted hypothesis and verified by existing data, an expression is derived to calculate response spectrum at the ground surface if the response spectrum at the basement rock is known. The fundamental ...

A multi-frequency study of the spectral index distribution in the SNR CTB 80
(EDP Sciences, 2005-12)
We have conducted a study at radio wavelengths of the spectral behaviour of the supernova remnant (SNR) CTB 80. Based on an homogenised data set of integrated flux densities, we calculated for the whole SNR a radio index ...
Particle acceleration in the superwinds of starburst galaxies
(EDP Sciences, 2018-08)
Context. Starbursts are galaxies undergoing massive episodes of star formation. The combined effect of stellar winds from hot stars and supernova explosions creates a high-temperature cavity in the nuclear region of these ...
Stochastic electron acceleration by temperature anisotropy instabilities under solar flare plasma conditions
(IOP Publishing, 2022)
Using 2D particle-in-cell plasma simulations, we study electron acceleration by temperature anisotropy instabilities, assuming conditions typical of above-the-loop-top sources in solar flares. We focus on the long-term ...
Stochastic electron acceleration by the whistler instability in a growing magnetic field
(IOP Publishing Ltd., 2017)
We use 2D particle-in-cell simulations to study the effect of the saturated whistler instability on the viscous heating and nonthermal acceleration of electrons in a shearing, collisionless plasma with a growing magnetic ...
