PublicationThe shapes of spiral arms in the S<SUP>4</SUP>G survey and their connection with stellar bars
Context. Spiral galaxies are very common in the local Universe, but their formation, evolution, and interplay with bars remain poorly understood after more than...

PublicationThe shell elliptical galaxy NGC 2865: evolutionary population synthesis of a kinematically distinct core
We report on the discovery of a rapidly corotating stellar and gas component in the nucleus of the shell elliptical NGC 2865. The stellar component extends ~ 0...

PublicationThe signature of high-velocity gas in the spectra of NGC 4151
The multiwavelength emission spectrum and associated velocity field of the Seyfert prototype NGC 4151 is modeled. Since the thirties NGC 4151 has been the...

PublicationThe simultaneous low state spectral energy distribution of 1ES 2344+514 from radio to very high energies
Context. BL Lacertae objects are variable at all energy bands on time scales down to minutes. To construct and interpret their spectral energy distribution (SED...

PublicationThe size and mass evolution of the massive galaxies over cosmic time
Once understood as the paradigm of passively evolving objects, the discovery that massive galaxies experienced an enormous structural evolution in the last ten...

PublicationThe Size Evolution of Galaxies since z~3: Combining SDSS, GEMS, and FIRES
We present the evolution of the luminosity-size and stellar mass-size relations of luminous (LV>~3.4×1010 h-270 Lsolar) and massive (M*>~3×1010 h-270 Msolar)...

PublicationThe size function of massive satellites from the R<SUB>e</SUB>-R<SUB>h</SUB> and M<SUB>star</SUB>-M<SUB>h</SUB> relations: constraining the role of environment
In previous work, we showed that a semi-empirical model in which galaxies in host dark matter haloes are assigned stellar masses via a stellar mass-halo mass...

PublicationThe Sloan Digital Sky Survey extended point spread functions
A robust and extended characterization of the point spread function (PSF) is crucial to extract the photometric information produced by deep imaging surveys...
