We present the new stellar population synthesis models based on the empirical stellar spectral library MILES, which can be regarded nowadays as standard in the...
An optically thick relativistic Keplerian accretion disk model is used to fit the broad component of the H-alpha, H-beta, and He I 5876 A emission line profiles...
Modelling the Mg[b] Spectroscopic Index with the Tunable Filters of OSIRIS
We present our first attempt to model a new metallicity indicator for old and intermediate aged stellar populations on the basis of the Mg[b] absorption index...
Molecular gas and star formation within 12 strong galactic bars observed with IRAM-30 m
Context. While some galactic bars show recent massive star formation (SF) along them, some others do not. Whether bars with low level of SF are a consequence of...
Molecular gas in galaxies, and evolution with redshift
I will review some recent results about the molecular content of galaxies and its dynamics, obtained from CO lines, dense tracers (HCN,HCO+), or the dust...
Morphology rather than environment drives the SFR-mass relation in the local universe
Exploiting a sample of 680 star-forming galaxies from the Padova Millennium Galaxy Group Catalog (PM2GC; Calvi, Poggianti & Vulcani 2011) in the range 0.038 ≤ z...
Multi-Wavelength Characterization of the Outskirts of Spiral Galaxies
We have explored late-type spiral galaxies with truncated radial surface brightness profiles. Based on the study of optical color profiles, [1] suggested that...
Multiband analysis of the surface brightness distributions of SB and SC spirals from CCD images. II - Bulge-disc decomposition
We analyze the structure of a small sample of galaxies, using a set of CCD images in standard photometric bands presented in a previous paper (Prieto et al...
Multiple stellar populations in globular clusters: Properties, origin, unsolved questions
Globular clusters (GCs) are fascinating objects nearly as old as the Universe that provide insight on a large variety of astrophysical and cosmological...
