Astrofísica de altas energías de objetos compactos
(Asociación Argentina de Astronomía, 2015)
En este trabajo se resumen los diferentes aspectos relacionados a la fenomenología que se deriva de la evolución y actividad de objetos compactos (enanas blancas, estrellas de neutrones y agujeros negros) que emiten a altas ...
The γ -ray sky seen at X-ray energies: II. The Swift hunt of Fermi BL Lac objects among unidentified γ -ray sources
(EDP Sciences, 2020-06)
Context. Nearly 50% of all sources detected by the Fermi Large Area Telescope are classified as blazars or blazar candidates, one of the most elusive classes of active galaxies. Additional blazars can also be hidden within ...
T Tauri stars as \gamma-ray source in the Rho Ophiuchi region
(Ediciones de la Asociación Argentina de Astronomía, 2020-07)
More than 30% of γ -ray sources detected in the last source catalog of the Fermi satellite have no observational counterpart at other frequencies. A significant fraction of these sources is positionally in agreement with ...
Multi-wavelength observations of the flaring gamma-ray blazar 3C 66A in 2008 october

Modeling the polarization of high-energy radiation from accreting black holes: A case study of XTE J1118+480
(Edp Sciences, 2016-03)
Context. The high-energy emission (400 keV-2 MeV) of Cygnus X-1, which is the best-studied Galactic black hole, was recently found to be strongly polarized. The origin of this radiation is still unknown. Aims. We suggest ...
The Cherenkov Telescope Array: an advanced facility for the Ground-based High Energy Gamma Ray Astronomy.
(Asociacion Argentina de Astronomia, 2013)
In the past 15 years, Very High Energy (VHE) γ-ray ex-periments as H.E.S.S., MAGIC and VERITAS have been very successfulunveiling the mysteries of the non thermal Universe using Cherenkovtelescopes based on Earth. The next ...
