Forever young white dwarfs : when stellar ageing stops
(EDP Sciences, 2021-05)
White dwarf stars are the most common end point of stellar evolution. The ultramassive white dwarfs are of special interest as they are related to type Ia supernovae explosions, merger events, and fast radio bursts. ...
Neutrino Oscillations and Decoherence in Short-GRB Progenitors
(IOP Publishing, 2019-02-12)
Neutrinos are produced in cosmic accelerators, like active galactic nuclei, blazars, supernova remnants and gamma-ray bursts (GRBs). On their way to the Earth they experience flavor oscillations. The interactions of the ...
GMRT survey of Cygnus OB2 region
(Societe des Sciences de Liege, 2019)
A good fraction of very high energy (VHE; > 100 GeV) sources do not have confirmed counterparts at any of the other branches of electromagnetc spectrum. In the extra-galactic sky, most of the VHE sources with counter-parts ...
The investigation of particle acceleration in colliding-wind massive binaries with SIMBOL-X
(Società Astronomica Italiana, 2008-12)
An increasing number of early-type (O and Wolf-Rayet) colliding wind binaries (CWBs) is known to accelerate particles up to relativistic energies. In this context, nonthermal emission processes such as inverse Compton (IC) ...
A multi-wavelength view of the cosmic ray confinement in star-forming galaxies
(Sissa, 2021-07)
Cosmic rays (CRs) are responsible for a tight correlation between the star formation rate (SFR) and the radio/γ-ray luminosity observed in star-forming galaxies (SFGs). This correlation can be explained by a linear scaling ...
