PublicationThe stellar populations of quiescent ultra-diffuse galaxies from optical to mid-infrared spectral energy distribution fitting
We use spectral energy distribution (SED) fitting to place constraints on the stellar population properties of 29 quiescent ultra-diffuse galaxies (UDGs) across...

PublicationThe stellar spectral features of nearby galaxies in the near infrared: tracers of thermally pulsing asymptotic giant branch stars?
We analyse the stellar absorption features in high signal-to-noise ratio (S/N) near-infrared (NIR) spectra of the nuclear region of 12 nearby galaxies, mostly...

PublicationThe structural properties of classical bulges and discs from z ̃ 2
We study the rest-frame optical mass-size relation of bulges and discs from z ̃ 2 to z ̃ 0 for a complete sample of massive galaxies in the CANDELS fields using...

PublicationThe structure of Abell 1351: a bimodal galaxy cluster with peculiar diffuse radio emission
We aim to review the internal structure and dynamics of the Abell 1351 cluster, shown to host a radio halo with a quite irregular shape. Our analysis is based...

PublicationThe structure of Andromeda II dwarf spheroidal galaxy
We analyse in detail the spatial distribution and kinematic properties of two different stellar populations in Andromeda II dwarf spheroidal galaxy. We obtained...

PublicationThe structure of the outer Galactic disc as revealed by IPHAS early A stars
This study is an investigation of the stellar density profile of the Galactic disc in the anticentre direction. We select over 40000 early A stars from INT/WFC...

PublicationThe sub-stellar birth rate from UKIDSS
We present a new sample of mid-L to mid-T dwarfs with effective temperatures of 1100-1700 K selected from the UKIDSS Large Area Survey (LAS) and confirmed with...
