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...

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 present new MMT/Hectochelle spectroscopic measurements for 257 stars observed along the line of sight to the ultrafaint dwarf galaxy Triangulum II (Tri II). Combining results...

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...

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...

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...

In this study, we compare the structural parameters of ultradiffuse galaxies (UDGs) to those of other dwarf galaxies and investigate whether UDGs form a distinct population. We...

We present spectroscopic data for 16369 stellar targets within and/or toward 38 dwarf spheroidal galaxies and faint star clusters within the Milky Way halo environment. All...

We present an extensive catalog of 5405 early-type dwarf (dE) galaxies located in the various environments, i.e., clusters, groups, and fields, of the local universe...

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 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...
