PublicaciónAbsence of significant cross-correlation between WMAP and SDSS
Aims: Several authors have claimed to detect a significant cross-correlation between microwave WMAP anisotropies and the SDSS galaxy distribution. We repeat...

PublicaciónAccretion and outflow in V404 Cyg
We study the optical evolution of the 2015 outburst in V404 Cyg, with emphasis on the peculiar nebular phase and subsequent decay to quiescence. From the decay...

PublicaciónAdventures of a tidally induced bar
Using N-body simulations, we study the properties of a bar induced in a discy dwarf galaxy as a result of tidal interaction with the Milky Way. The bar forms at...

PublicaciónAGB dust and gas ejecta in extremely metal-poor environments
We present asymptotic giant branch (AGB) models of metallicity Z = 10-4 and 3 × 10-4, with the aim of understanding how the gas enrichment and the dust...

PublicaciónAGB Stars and Their Circumstellar Envelopes. I. the VULCAN Code
The interplay between AGB interiors and their outermost layers, where molecules and dust form, is a problem of high complexity. As a consequence, physical...
