The faintest dwarf galaxies

JD Simon - Annual Review of Astronomy and Astrophysics, 2019 - annualreviews.org
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 …

Dark matter in dwarf spheroidal galaxies and indirect detection: a review

LE Strigari - Reports on Progress in Physics, 2018 - iopscience.iop.org
Indirect dark matter searches targeting dwarf spheroidal galaxies (dSphs) have matured
rapidly during the past decade. This has been because of the substantial increase in …

Proper motions, orbits, and tidal influences of milky way dwarf spheroidal galaxies

AB Pace, D Erkal, TS Li - The Astrophysical Journal, 2022 - iopscience.iop.org
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 …

Gaia proper motions and orbits of the ultra-faint milky way satellites

JD Simon - The Astrophysical Journal, 2018 - iopscience.iop.org
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 …

Ultra-light dark matter is incompatible with the Milky Way's dwarf satellites

M Safarzadeh, DN Spergel - The Astrophysical Journal, 2020 - iopscience.iop.org
The density profiles of dwarf galaxies are a highly varied set. If the dark matter is an ultra-
light particle such as axions, then simulations predict a distinctive and unique profile. If the …

Revised and new proper motions for confirmed and candidate Milky Way dwarf galaxies

AW McConnachie, KA Venn - The Astronomical Journal, 2020 - iopscience.iop.org
A new derivation of systemic proper motions of Milky Way satellites is presented and applied
to 59 confirmed or candidate dwarf galaxy satellites using Gaia Data Release 2. This …

Small-scale stellar haloes: detecting low surface brightness features in the outskirts of Milky Way dwarf satellites

J Jensen, CR Hayes, F Sestito… - Monthly Notices of …, 2024 - academic.oup.com
Dwarf galaxies are valuable laboratories for dynamical studies related to dark matter and
galaxy evolution, yet it is currently unknown just how physically extended their stellar …

Ultra-light dark matter in ultra-faint dwarf galaxies

E Calabrese, DN Spergel - Monthly Notices of the Royal …, 2016 - academic.oup.com
Abstract Cold Dark Matter (CDM) models struggle to match the observations at galactic
scales. The tension can be reduced either by dramatic baryonic feedback effects or by …

Triangulum II. Not especially dense after all

EN Kirby, JG Cohen, JD Simon… - The Astrophysical …, 2017 - iopscience.iop.org
Abstract Among the Milky Way satellites discovered in the past three years, Triangulum II
has presented the most difficulty in revealing its dynamical status. Kirby et al. identified it as …
