Origin of 10(15)-10(16) G magnetic fields in the central engine of gamma ray bursts
(IOP PUBLISHING LTD, 2010)
Various authors have suggested that the gamma-ray burst (GRB) central engine is a rapidly rotating, strongly magnetized, (similar to 10(15)-10(16) G) compact object. The strong magnetic field can accelerate and collimate ...
Metallicity effects in long gamma-ray burst populations in a ΛCDM Universe
(Elsevier Science, 2018-11)
The use of long γ-ray burst as star formation tracers is suspected to be affected by a possible dependence of the production or luminosity of these sources on the metallicity of their stellar progenitors. Selection effects ...
Hot gas around SN 1998bw: inferring the progenitor from its environment
(EDP Sciences, 2017)
Spatially resolved spectroscopy of the environments of explosive transients carries detailed information about the physical properties of the stellar population that gave rise to the explosion, and thus the progenitor ...

THE DISCOVERY OF A MOLECULAR CAVITY IN THE NORMA NEAR ARM ASSOCIATED WITH H.E.S.S γ -RAY SOURCE LOCATED IN THE DIRECTION OF WESTERLUND 1
(The American Astronomical Society, 2010-04-10)
We report on the discovery of a molecular cavity in the Norma near arm in the general direction of Westerlund
1 (Wd1), but not associated with it. The cavity has a mean radial velocity of −91.5 km s−1, which differs by ...
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 ...
