Optical emission from massive donors in ULX binary systems

open access: yes, 2007
We present evolutionary tracks of binary systems with high mass companion stars and stellar-through-intermediate mass BHs. Using Eggleton's stellar evolution code, we compute the luminosity produced by accretion from the donor during its entire evolution.

A Corona Australis cloud filament seen in NIR scattered light I. Comparison with extinction of background stars

open access: yes, 2008
With current near-infrared (NIR) instruments the near-infrared light scattered from interstellar clouds can be mapped over large areas. The surface brightness carries information on the line-of-sight dust column density.

Pensar la rebeldía como objeto de estudio en la Sociología: una disposición generadora de experiencias y repertorios de acción subjetivos [PDF]

open access: yesPensamiento al Margen, 2018
Este artículo presenta una propuesta de estudio de la rebeldía en las ciencias sociales a través del desarrollo teórico de varios elementos, de cuya conjunción se propone una definición mediante el concepto de disposición.

Dark Matter Mini-halo around the Compact Objects: the Formation, Evolution and Possible Contribution to the Cosmic Ray Electrons/Positrons

open access: yes, 2011
Dark matter particles may be captured by a star and then thermalized in the star's core. At the end of its life a massive star collapses suddenly and a compact object is formed. The dark matter particles redistribute accordingly.

Molecular gas content of galaxies in the Hydra-Centaurus supercluster [PDF]

open access: yes
A survey of bright spiral galaxies in the Hydra-Centaurus supercluster for the CO(1-0) transition at 115 GHz was performed with the 15m Swedish-ESO submillimeter telescope (SEST). A total of 30 galaxies have been detected in the CO(1-0) transition out of

Delayed neutrino-driven supernova explosions aided by the standing accretion-shock instability

open access: yes, 2008
We present results of 2D hydrodynamic simulations of stellar core collapse, which confirm that the neutrino-heating mechanism remains viable for the explosion of a wider mass range of supernova progenitors with iron cores.

15-M and the digital fifth-column

open access: yesRevista Teknokultura, 2011
Social movements around May 15th have changed the political landscape. The use of some features such as networking, pacifism, transversality, represents a challenge for official politicians.

KamLAND Sensitivity to Neutrinos from Pre-Supernova Stars

open access: yes, 2016
In the late stages of nuclear burning for massive stars ($M>8~M_{\sun}$), the production of neutrino-antineutrino pairs through various processes becomes the dominant stellar cooling mechanism. As the star evolves, the energy of these neutrinos increases
