On the large escape of ionizing radiation from GEHRs

M. Castellanos, A. I. Diaz, G. Tenorio-Tagle

A thorough analysis of well studied giant HII regions on galactic discs for which we know the ionizing stellar population, the gas metallicity and the Wolf-Rayet population, leads…

Dimensional reduction, SL(2,C)-equivariant bundles and stable holomorphic chains

Luis Álvarez-Cónsul, Oscar García-Prada

In this paper we study gauge theory on SL(2,C)-equivariant bundles over XxP^1, where X is a compact Kahler manifold, P^1 is the complex projective line, and the action of SL(2,C) i…

Solar neutrino experiments and Borexino perspectives

P. Aliani, V. Antonelli, M. Picariello +1

We present an updated analysis of all the data available about solar neutrinos, including the charged current SNO results. The best fit of the data is obtained in the Large Mixing…

Electron correlation effects and ferromagnetism in Iron

Pablo Pou, Fernando Flores, Jose Ortega +2

Electron correlation effects in Fe are analyzed using a first principles LCAO-scheme. In our approach, we first use a local orbital DFT-LDA solution to introduce a Hubbard Hamilton…

Oxygen and nitrogen abundances in Virgo and field spirals

L. S. Pilyugin, Mercedes Molla, Federico Ferrini +1

The oxygen and nitrogen abundances in the HII regions of the nine Virgo spirals of the sample from Skillman et al (1996) and in nine field spiral galaxies are re-determined with th…

Hitchin-Kobayashi correspondence, quivers, and vortices

Luis Álvarez-Cónsul, Oscar García-Prada

A twisted quiver bundle is a set of holomorphic vector bundles over a complex manifold, labelled by the vertices of a quiver, linked by a set of morphisms twisted by a fixed collec…
