AGC 226178 and NGVS 3543: Two deceptive dwarfs towards Virgo
Michael G. Jones, David J. Sand, Michele Bellazzini +21
The two sources AGC 226178 and NGVS 3543, an extremely faint, clumpy, blue stellar system and a low surface brightness dwarf spheroidal, are adjacent systems in the direction of th…
Hubble Space Telescope Observations of NGC 253 Dwarf Satellites: Discovery of Three Ultra-faint Dwarf Galaxies
Burçin Mutlu-Pakdil, David J. Sand, Denija Crnojević +8
We present deep Hubble Space Telescope imaging of five faint dwarf galaxies associated with the nearby spiral NGC 253 (D3.5 Mpc). Three of these are newly discovered ultra…
Eridanus IV: an Ultra-Faint Dwarf Galaxy Candidate Discovered in the DECam Local Volume Exploration Survey
W. Cerny, A. B. Pace, A. Drlica-Wagner +29
We present the discovery of a candidate ultra-faint Milky Way satellite, Eridanus IV (DELVE J05050931), detected in photometric data from the DECam Local Volume Exploration surv…
RR Lyrae stars in the newly discovered ultra-faint dwarf galaxy Centaurus I
C. E. Martínez-Vázquez, W. Cerny, A. K. Vivas +22
We report the detection of three RR Lyrae (RRL) stars (two RRc and one RRab) in the ultra-faint dwarf (UFD) galaxy Centaurus I (CenI) and two Milky Way (MW) Scuti/SX Phoenicis…
Resolved Dwarf Galaxy Searches within ~5 Mpc with the Vera Rubin Observatory and Subaru Hyper Suprime-Cam
Burçin Mutlu-Pakdil, David J. Sand, Denija Crnojević +7
We present a preview of the faint dwarf galaxy discoveries that will be possible with the Vera C. Rubin Observatory and Subaru Hyper Suprime-Cam in the next decade. In this work, w…
Satellites Around Milky Way Analogs: Tension in the Number and Fraction of Quiescent Satellites Seen in Observations Versus Simulations
Ananthan Karunakaran, Kristine Spekkens, Kyle A. Oman +13
We compare the star-forming properties of satellites around Milky Way (MW) analogs from the Stage~II release of the Satellites Around Galactic Analogs Survey (SAGA-II) to those fro…
