Within the Local Universe galaxies can be studied in great detail star by star, and here we
review the results of quantitative studies in nearby dwarf galaxies. The color-magnitude …

The lowest luminosity (L) Milky Way satellite galaxies represent the extreme lower limit of the
galaxy luminosity function. These ultra-faint dwarfs are the oldest, most dark matter …

Context. Gaia DR3 contains 1.8 billion sources with G-band photometry, 1.5 billion of which
with G BP and G RP photometry, complemented by positions on the sky, parallax, and …

The dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are some of the most dark
matter (DM) dominated objects known. We report on γ-ray observations of Milky Way dSphs …

We combine Gaia early data release 3 astrometry with accurate photometry and utilize a
probabilistic mixture model to measure the systemic proper motion of 52 dwarf spheroidal …

We study the link between baryons and dark matter (DM) in 240 galaxies with spatially
resolved kinematic data. Our sample spans 9 dex in stellar mass and includes all …

A proper understanding of the Milky Way (MW) dwarf galaxies in a cosmological context
requires knowledge of their 3D velocities and orbits. However, proper motion (PM) …

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 …

Aims. We perform a comprehensive determination of the systemic proper motions of 74
dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia early data …

The dwarf spheroidal satellite galaxies of the Milky Way are some of the most dark-matter-
dominated objects known. Due to their proximity, high dark matter content, and lack of …
