We make use of the unprecedented depth, spatial resolution, and field of view of the Euclid Early Release Observations (EROs) of the Perseus galaxy cluster to detect and...

We use a compilation of disc galaxy rotation curves to assess the role of the luminous component ('baryons') in the rotation curve diversity problem. As in earlier work, we find...

We used the H{alpha} images from a large sample of nearby late-type dwarf galaxies to investigate properties of their emission structure. The sample consists of 300 galaxies of...

We present a Bayesian method to identify multiple (chemodynamic) stellar populations in dwarf spheroidal galaxies (dSphs) using velocity, metallicity, and positional stellar...

We report the discovery of Tucana B, an isolated ultra-faint dwarf galaxy at a distance of D=1.4Mpc. Tucana B was found during a search for ultra-faint satellite companions to...

We present the final sample of the Exploration of Local VolumE Satellites (ELVES) survey, a survey of the dwarf satellites of a nearly volume-limited sample of Milky Way...

We use a complete sample of 211 nearby (z<0.08), dwarf (10^8^M_{sun}<M*<10^9.5^M{sun}) galaxies in low-density environments, to study their structural properties:...

We have studied the extent of the Red Giant Branch stellar population in the Fornax dwarf spheroidal galaxy using the spatially extended and homogeneous data set from Gaia EDR3....

Nuclear star clusters (NSCs) are a common phenomenon in galaxy centres and are found in a vast majority of galaxies of intermediate stellar mass ~10^9^M_{sun}. Recent...

The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream....

Understanding the formation and evolution of low surface brightness galaxies (LSBGs) is critical for explaining their wide-ranging properties. However, studies of LSBGs in deep...

We present a catalogue of 285 RR Lyrae stars (RRLs) in the Draco dwarf spheroidal (dSph) galaxy, obtained by combining data from a number of different surveys including the Data...

We investigate the properties of long tidal tails using the largest to date sample of 461 merging galaxies with log(M_/M{sun})>=9.5 within 0.2=<z=<1 from the COSMOS...

The Study of H{alpha} from Dwarf Emissions (SH{alpha}DE) is a high spectral resolution (R=13500) H{alpha} integral field survey of 69 dwarf galaxies with stellar masses...

Data from Gaia DR2 and The Apache Point Observatory Galactic Evolution Experiment surveys revealed a relatively new component in the inner Galactic halo, which is likely the...

Time series observations of a single dithered field centred on the diffuse dwarf satellite galaxy Crater II were obtained with the Dark Energy Camera (DECam) at the 4m Blanco...

This paper presents improved constraints on the low-mass stellar initial mass function (IMF) of the Bootes I (Boo I) ultrafaint dwarf galaxy, based on our analysis of recent...

We determine three independent Population II distance moduli to the Fornax dwarf spheroidal (dSph) galaxy, using wide-field, ground-based VI imaging acquired with the...

We demonstrate that using up to seven stellar abundance ratios can place observational constraints on the star formation histories (SFHs) of Local Group dSphs, using Sculptor...

The Fornax dwarf spheroidal galaxy has an anomalous number of globular clusters, five, for its stellar mass. There is a longstanding debate about a potential sixth globular...
