Positional, structural, and dynamical parameters for all dwarf galaxies in and around the Local Group are presented, and various aspects of our observational understanding of this volume-limited sample are discussed. Over 100 nearby galaxies that have distance estimates reliably placing them within 3 Mpc of the Sun are identified. This distance threshold samples dwarfs in a large range of environments, from the satellite systems of the MW and M31, to the quasi-isolated dwarfs in the outer… 
Isolated dwarf galaxies in the Local Group
Abstract The Solo (Solitary local) Dwarf Galaxy Survey is a volume limited sample of all nearby (< 3 Mpc) and isolated (> 300 kpc from the Milky Way or M31) dwarfs, with wide-field g and i imaging.
The properties of dwarf spheroidal galaxies in the Cen A group
Dwarf spheroidal galaxies (dSphs) have been extensively investigated in the Local Group, but their low luminosity and surface brightness make similar work in more distant galaxy groups challenging.
Dwarf galaxy planes: the discovery of symmetric structures in the Local Group
Both major galaxies in the Local Group (LG) are surrounded by thin planes of mostly co-orbiting satellite galaxies, the vast polar structure (VPOS) around the Milky Way (MW) and the Great Plane of
The Leo-I group: new dwarf galaxy and ultra diffuse galaxy candidates
Context. The study of dwarf galaxies and their environments provides crucial test beds for predictions of cosmological models and insights into the structure formation on small cosmological scales.
The Number of Dwarf Satellites of Disk Galaxies versus their Bulge Mass in the Standard Model of Cosmology
There is a correlation between bulge mass of the three main galaxies of the Local Group (LG), i.e. M31, Milky Way (MW), and M33, and the number of their dwarf spheroidal galaxies. A similar
Faint satellite population of the NGC-3175 Group – a Local Group analogue
In this paper we identify and study the properties of low mass dwarf satellites of a nearby Local Group analogue - the NGC-3175 galaxy group with the goal of investigating the nature of the lowest
The dwarf galaxy satellite system of Centaurus A
Dwarf galaxy satellite systems are essential probes to test models of structure formation, making it necessary to establish a census of dwarf galaxies outside of our own Local Group. We present deep
The M 101 group complex: new dwarf galaxy candidates and spatial structure
Context. The fine details of the large-scale structure in the local Universe provide important empirical benchmarks for testing cosmological models of structure formation. Dwarf galaxies are key
The dynamics of isolated Local Group galaxies
We measured velocities of 862 individual red giant stars in seven isolated dwarf galaxies in the Local Group: NGC 6822, IC 1613, VV 124 (UGC 4879), the Pegasus dwarf irregular galaxy (DDO 216), Leo
Dwarf Galaxies in the Halo of NGC 891
We report the results of a survey of the region within 40 arcmin of NGC 891, a nearby nearly perfectly edge-on spiral galaxy. Candidate "non-stars" with diameters greater than 15 arcsec were selected

A Trio of New Local Group Galaxies with Extreme Properties
TLDR
The discovery of three new dwarf galaxies in the Local Group are reported on, which indicate that the full parameter space occupied by dwarf galaxies is not yet sampled, although this is an essential prerequisite for successfully and consistently linking these systems to the predicted cosmological dark matter substructure.
H I in Local Group Dwarf Galaxies and Stripping by the Galactic Halo
We examine the H I content and environment of all of the Local Group dwarf galaxies (M tot < 1010 M ☉), including the numerous newly discovered satellites of the Milky Way and M31. All of the new
