We present a study aimed at understanding the physical phenomena underlying the formation and evolution of galaxies following a data-driven analysis of...
What is the Milky Way outer halo made of?. High resolution spectroscopy of distant red giants
In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to...
When 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...
When 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...
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...
Which 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...
Which 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...
WHT 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...
Young stellar bars in disk galaxies experience a vertical buckling instability that terminates their growth and thickens them, resulting in a characteristic...
