Three Quenched, Faint Dwarf Galaxies in the Direction of NGC 300: New Probes of Reionization and Internal Feedback
D. J. Sand, B. Mutlu-Pakdil, M. G. Jones +18
We report the discovery of three faint and ultra-faint dwarf galaxies -- Sculptor A, Sculptor B and Sculptor C -- in the direction of NGC 300 (D=2.0 Mpc), a Large Magellanic Cloud-…
Corvus A: A low-mass, isolated galaxy at 3.5 Mpc
Michael G. Jones, David J. Sand, Burcin Mutlu-Pakdil +9
We report the discovery of Corvus A, a low-mass, gas-rich galaxy at a distance of approximately 3.5 Mpc, identified in DR10 of the Dark Energy Camera Legacy Imaging Survey during t…
Subhalos are Anisotropically Distributed and Aligned with the Smooth Matter Distribution of Their Host Halos
Lorena Mezini, Andrew R. Zentner, Kuan Wang +1
We investigate the distributions of subhalos about their hosts in two suites of zoom-in N-body simulations of halo growth -- one suite focused on Milky Way-Mass halos ($\sim 10^{12…
Dark no more: The low luminosity stellar counterpart of a dark cloud in the Virgo cluster
Michael G. Jones, Steven Janowiecki, Swapnaneel Dey +9
We have discovered the stellar counterpart to the ALFALFA Virgo 7 cloud complex, which has been thought to be optically dark and nearly star-free since its discovery in 2007. This…
The Faint Satellite System of NGC 253: Insights into Low-Density Environments and No Satellite Plane
Burçin Mutlu-Pakdil, David J. Sand, Denija Crnojević +12
We have conducted a systematic search around the Milky Way (MW) analog NGC 253 (D=3.5 Mpc), as a part of the Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) - a Magella…
All Puffed Up: Exploring Ultra-diffuse Galaxy Origins through Galaxy Interactions
Catherine Fielder, Michael Jones, David Sand +5
We present new follow-up observations of two ultra-diffuse galaxies (UDGs) selected for their distorted morphologies and tidal features, suggestive of tidal influence. Using Hubble…
