The Origin of the 300 km s‑1 Stream near Segue 1
We present a search for new members of the 300 km s‑1 stream (300S) near the dwarf galaxy Segue 1 using wide-field survey data. We identify 11 previously...
The origin of the LMC stellar bar: clues from the SFH of the bar and inner disc
We discuss the origin of the Large Magellanic Cloud (LMC) stellar bar by comparing the star formation histories (SFHs) obtained from deep colour-magnitude...
The origin of the planetary nebula M 1-16. A morpho-kinematic and chemical analysis
We investigated the origin of the Planetary Nebula (PN) M 1-16 using narrow-band optical imaging, and high- and low-resolution optical spectra to perform a...
The Oxygen versus Sodium (Anti)Correlation(S) in ω Cen
Recent examination of large samples of ω Cen giants shows that, as in mono-metallic globular clusters, sodium versus oxygen anticorrelation is present within...
The PAndAS View of the Andromeda Satellite System. III. Dwarf Galaxy Detection Limits
We determine the detection limits of the search for dwarf galaxies in the Pan-Andromeda Archaeological Survey (PAndAS) using the algorithm developed by the...
The PAndAS View of the Andromeda Satellite System. IV. Global Properties
We build a statistical framework to infer the global properties of the satellite system of the Andromeda galaxy (M31) from the properties of individual dwarf...
The Phantom Dark Matter Halos of the Local Volume in the Context of Modified Newtonian Dynamics
We explore the predictions of Milgromian gravity (MOND) in the local universe by considering the distribution of the "phantom" dark matter (PDM) that would...
The Photo-Astrometric vertical tracer density of the Milky Way - I. The method
We introduce a method to infer the vertical distribution of stars in the Milky Way using a Poisson likelihood function, with a view to applying our method to...
The photo-astrometric vertical tracer density of the Milky Way - II. Results from Gaia
We use Gaia photometry and astrometry to estimate the vertical spatial structure of the Milky Way at the Solar radius, formally accounting for sample...
