A search for faint resolved galaxies beyond the Milky Way in DES Year 6: A new faint, diffuse dwarf satellite of NGC 55
M. McNanna, K. Bechtol, S. Mau +63
We report results from a systematic wide-area search for faint dwarf galaxies at heliocentric distances from 0.3 to 2 Mpc using the full six years of data from the Dark Energy Surv…
The Hubble Space Telescope Survey of M31 Satellite Galaxies II. The Star Formation Histories of Ultra-Faint Dwarf Galaxies
A. Savino, D. R. Weisz, E. D. Skillman +34
We present the lifetime star formation histories (SFHs) for six ultra-faint dwarf (UFD; , ) satellite galaxies of M31 based on…
The Elusive Distance Gradient in the Ultra-Faint Dwarf Galaxy Hercules: A Combined Hubble Space Telescope and Gaia View
Burçin Mutlu-Pakdil, David J. Sand, Denija Crnojević +6
The ultra-faint dwarf galaxy Hercules has an extremely elongated morphology with both photometric overdensities and kinematic members at large radii, suggesting that it may be tida…
Signatures of Tidal Disruption in Ultra-Faint Dwarf Galaxies: A Combined HST, Gaia, and MMT/Hectochelle Study of Leo V
Burçin Mutlu-Pakdil, David J. Sand, Matthew G. Walker +10
The ultra-faint dwarf galaxy Leo V has shown both photometric overdensities and kinematic members at large radii, along with a tentative kinematic gradient, suggesting that it may…
Extending the Globular Cluster System-Halo Mass Relation to the Lowest Galaxy Masses
Duncan A. Forbes, Justin I. Read, Mark Gieles +1
High mass galaxies, with halo masses , reveal a remarkable near-linear relation between their globular cluster (GC) system mass and their host galaxy…
CDM Predictions for the Satellite Population of M33
Ekta Patel, Jeffrey L. Carlin, Erik J. Tollerud +2
Triangulum (M33) is the most massive satellite galaxy of Andromeda (M31), with a stellar mass of about . Based on abundance matching techniques, M33's tota…
Probing dark matter with star clusters: a dark matter core in the ultra-faint dwarf Eridanus II
Filippo Contenta, Eduardo Balbinot, James A. Petts +6
We present a new technique to probe the central dark matter (DM) density profile of galaxies that harnesses both the survival and observed properties of star clusters. As a first a…
The contribution of dissolving star clusters to the population of ultra-faint objects in the outer halo of the Milky Way
Filippo Contenta, Mark Gieles, Eduardo Balbinot +1
In the last decade, several ultra faint objects (UFOs, ) have been discovered in the outer halo of the Milky Way. For some of these objects it is not clear whether…
Exploding Satellites -- The Tidal Debris of the Ultra-Faint Dwarf Galaxy Hercules
Andreas H. W. Küpper, Kathryn V. Johnston, Steffen Mieske +2
The ultra-faint satellite galaxy Hercules has a strongly elongated and irregular morphology with detections of tidal features up to 1.3 deg (3 kpc) from its center. This suggests t…
Dynamical evidence for a strong tidal interaction between the Milky Way and its satellite, Leo V
Michelle L. M. Collins, Erik J. Tollerud, David J. Sand +3
We present a chemodynamical analysis of the Leo~V dwarf galaxy, based on Keck II DEIMOS spectra of 8 member stars. We find a systemic velocity for the system of $\langle v_r\rangle…
At the survey limits: discovery of the Aquarius 2 dwarf galaxy in the VST ATLAS and the SDSS data
G. Torrealba, S. E. Koposov, V. Belokurov +7
We announce the discovery of the Aquarius~2 dwarf galaxy, a new distant satellite of the Milky Way, detected on the fringes of the VST ATLAS and the SDSS surveys. The object was or…
Probing the boundary between star clusters and dwarf galaxies: A MUSE view on the dynamics of Crater/Laevens I
Karina Voggel, Michael Hilker, Holger Baumgardt +5
We present MUSE observations of the debated ultra faint stellar system Crater. We spectroscopically confirm 26 member stars of this system via radial velocity measurements. We deri…
Dark matter cores all the way down
J. I. Read, O. Agertz, M. L. M. Collins
We use high resolution simulations of isolated dwarf galaxies to study the physics of dark matter cusp-core transformations at the edge of galaxy formation: M200 = 10^7 - 10^9 Msun…
