In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to...

PublicationWhen disks collide: major and minor mergers in disk galaxies
We present the surface brightness profile fitting of a sample of double nucleus disk galaxies, minor merger candidates. We have decomposed these systems into...

PublicationWhen Is a Bulge Not a Bulge? Inner Disks Masquerading as Bulges in NGC 2787 and NGC 3945
We present a detailed morphological, photometric, and kinematic analysis of two barred S0 galaxies with large, luminous inner disks inside their bars. We show...

PublicationWhere does galactic dust come from?
Here we investigate the origin of the dust mass (Mdust) observed in the Milky Way (MW) and of dust scaling relations found in a sample of local galaxies from...

PublicationWhich Galaxies Host Bars and Disks? A Study of the Coma Cluster
We present a study of the bar fraction in the Coma Cluster galaxies based on a sample of ~190 galaxies selected from the Sloan Digital Sky Survey Data Release 6...

PublicationWhich haloes host Herschel-ATLAS galaxies in the local Universe?
We measure the projected cross-correlation between low-redshift (z < 0.5) far-infrared selected galaxies in the science demonstration phase (SDP) field of the...

PublicationWHT follow-up observations of extremely metal-poor stars identified from SDSS and LAMOST
Aims: We have identified several tens of extremely metal-poor star candidates from SDSS and LAMOST, which we follow up with the 4.2 m William Herschel Telescope...

PublicationWhy Buckling Stellar Bars Weaken in Disk Galaxies
Young stellar bars in disk galaxies experience a vertical buckling instability that terminates their growth and thickens them, resulting in a characteristic...

PublicationWide Field Optical Photometry of the Carina Dwarf Spheroidal Galaxy
We present optical photometry of the Carina Dwarf Spheroidal (dSph) Galaxy. Data have been collected with CCD mosaic cameras available at the 2.2m ESO/MPI and...
