Metallicity profiles of ultradiffuse galaxies in NIHAO simulations
Supernovae feedback driven expansion has proven to be a viable mechanism to explain the average properties, such as size, colour, mass, and internal kinematics...
Mid-IR cosmological spectrophotometric surveys from space: Measuring AGN and star formation at the cosmic noon with a SPICA-like mission
We use the SPace Infrared telescope for Cosmology and Astrophysics (SPICA) project as a template to demonstrate how deep spectrophotometric surveys covering...
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...
