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 …

We use observations of ultrafaint dwarf (UFD) galaxies to constrain the particle mass of
ultralight dark matter. Potential fluctuations created by wave interference in virialized “fuzzy” …

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 …

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 …

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) …

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 …

We discuss the use and importance of pulsating variable stars as population tracers in Local
Group galaxies. Among bright variable crossing the classical instability strip, we mostly focus …

We present structural parameters from a wide-field homogeneous imaging survey of Milky
Way satellites carried out with the MegaCam imagers on the 3.6 m Canada–France–Hawaii …

The second data release from the Gaia mission (DR2) provides a comprehensive and
unprecedented picture of the motions of astronomical sources in the plane of the sky …
