Gamma-rays from the compact colliding wind region in Cyg OB2 #5
(American Institute of Physics, 2012)
In this contribution we model the non-thermal emission (from radio toγ-rays) produced in the compact (and recently detected) collidingwind region in the multiple stellar system Cyg OB2 #5. We focus ourstudy on the detectability ...
Investigaciones sobre cascadas electromagnéticasInvestigations on photon-pair cascades
(Paideia, 2013)
Results from the latest generations of telescopes have revealed a rich sky at high and very high energies with more than a thousand sources at GeV energies and more than a hundred sources at TeV energies. The sources are ...
Non-thermal radiation from a runaway early-type star
(American Institute of Physics, 2012)
HD 195592 is an O-type supergiant star, known as a well-established runaway. Recently, a Fermi γ-ray source (2FGL J2030.7+4417) with a position compatible with that of HD 195592 has been reported. Our goal is to explore a ...
The non-thermal broadband spectral energy distribution of radio galaxies
(Cambridge University Press, 2012)
I present a model for the non-thermal production of electromagnetic radiation in the jets of radio galaxies. The model goes far beyond the simple one-zone models usually applied to these sources. The transport equation is ...
Radiation from black hole accretion in f(R) gravity
(American Institute of Physics, 2012)
We calculate the thermal radiation from a thin accretion disk around a rotating black hole taken into account strong field effects. We compare the resulting spectrum in general relativity (GR), with the spectra obtained ...
