Hubble Space Telescope Observations of Two Faint Dwarf Satellites of Nearby LMC Analogs from MADCASH
Jeffrey L. Carlin, Burcin Mutlu-Pakdil, Denija Crnojevic +11
We present a deep Hubble Space Telescope (HST) imaging study of two dwarf galaxies in the halos of Local Volume Large Magellanic Cloud (LMC) analogs. These dwarfs were discovered a…
Eridanus II: A Fossil from Reionization with an Off-Center Star Cluster
Joshua D. Simon, Thomas M. Brown, Alex Drlica-Wagner +10
We present deep Hubble Space Telescope (HST) photometry of the ultra-faint dwarf galaxy Eridanus II (Eri II). Eri II, which has an absolute magnitude of M_V = -7.1, is located at a…
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…
A Deeper Look at DES Dwarf Galaxy Candidates: Grus I and Indus II
Sarah A. Cantu, Andrew B. Pace, Jennifer Marshall +11
We present deep - and -band Magellan/Megacam photometry of two dwarf galaxy candidates discovered in the Dark Energy Survey (DES), Grus I and Indus II (DES J2038-4609). For t…
The Satellite Luminosity Function of M101 into the Ultra-Faint Dwarf Galaxy Regime
P. Bennet, D. J. Sand, D. Crnojevic +4
We have obtained deep Hubble Space Telescope (HST) imaging of four faint and ultra-faint dwarf galaxy candidates in the vicinity of M101 - Dw21, Dw22, Dw23 and Dw35, originally dis…
A Gaia-based catalog of candidate stripped nuclei and luminous globular clusters in the halo of Centaurus A
Karina T. Voggel, Anil C. Seth, David J. Sand +4
Tidally stripped galaxy nuclei and luminous globular clusters (GCs) are important tracers of the halos and assembly histories of nearby galaxies, but are difficult to reliably iden…
