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…
Pavo: Stellar feedback in action in a low-mass dwarf galaxy
Michael G. Jones, Martin P. Rey, David J. Sand +13
MeerKAT observations of the recently discovered, extremely low mass galaxy, Pavo, have revealed a neutral gas (HI) reservoir that was undetected in archival HI single dish data. We…
Gas and star formation in satellites of Milky Way analogs
Michael G. Jones, David J. Sand, Ananthan Karunakaran +9
We have imaged the entirety of eight (plus one partial) Milky Way-like satellite systems, a total of 42 (45) satellites, from the Satellites Around Galactic Analogs (SAGA) II catal…
Young, blue, and isolated stellar systems in the Virgo Cluster. II. A new class of stellar system
Michael G. Jones, David J. Sand, Michele Bellazzini +21
We discuss five blue stellar systems in the direction of the Virgo cluster, analogous to the enigmatic object SECCO 1 (AGC 226067). These objects were identified based on their opt…
A census of dwarf galaxy satellites around LMC-mass galaxy NGC 2403
Jeffrey L. Carlin, David J. Sand, Burcin Mutlu-Pakdil +11
We present the first comprehensive census of the satellite population around a Large Magellanic Cloud (LMC) stellar-mass galaxy, as part of the Magellanic Analog Dwarf Companions a…
VLT Spectroscopy of Ultra-Faint Dwarf Galaxies. 1. Boötes I, Leo IV, Leo V
Sydney Jenkins, Ting S. Li, Andrew B. Pace +3
We perform consistent reductions and measurements for three ultra-faint dwarf galaxies (UFDs): Boötes I, Leo IV and Leo V. Using the public archival data from the GIRAFFE spectrog…
Evidence for Ultra-Diffuse Galaxy Formation Through Tidal Heating of Normal Dwarfs
Michael G. Jones, Paul Bennet, Burcin Mutlu-Pakdil +5
We have followed up two ultra-diffuse galaxies (UDGs), detected adjacent to stellar streams, with Hubble Space Telescope (HST) imaging and HI mapping with the Jansky Very Large Arr…
SEAMLESS Survey: Four Faint Dwarf Galaxies Tracing Low-Mass Galaxy Evolution Across Environments
Catherine E. Fielder, Michael G. Jones, David J. Sand +11
We report on four Local Volume dwarf galaxies identified through our ongoing SEmi-Automated Machine LEarning Search for Semi-resolved galaxies (SEAMLESS): Hydrus A, LEDA 486718, Ce…
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…
Star formation histories and gas content limits of three ultra-faint dwarfs on the periphery of M31
Michael G. Jones, David J. Sand, Paul Bennet +9
We present Hubble Space Telescope (HST) imaging of Pegasus V and Pisces VII, along with a re-analysis of the archival imaging of Pegasus W, and Jansky Very Large Array (VLA) neutra…
DELVE-ing into the Jet: a thin stellar stream on a retrograde orbit at 30 kpc
Peter Ferguson, Nora Shipp, Alex Drlica-Wagner +20
We perform a detailed photometric and astrometric analysis of stars in the Jet stream using data from the first data release of the DECam Local Volume Exploration Survey (DELVE) DR…
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…
NANCY: Next-generation All-sky Near-infrared Community surveY
Jiwon Jesse Han, Arjun Dey, Adrian M. Price-Whelan +206
The Nancy Grace Roman Space Telescope is capable of delivering an unprecedented all-sky, high-spatial resolution, multi-epoch infrared map to the astronomical community. This oppor…
The Disturbed and Globular Cluster-Rich Ultra-diffuse Galaxy UGC 9050-Dw1
Catherine E. Fielder, Michael G. Jones, David J. Sand +5
We investigate the ultra-diffuse galaxy (UDG) UGC 9050-Dw1, which was selected because of its disturbed morphology as part of a larger sample of UDGs that display evidence for sign…
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…
Searching for Intermediate Mass Black Holes in galaxies with Low Luminosity AGN: A multiple-method approach
Filippos Koliopanos, Bogdan C. Ciambur, Alister W. Graham +7
Aims: This work is the first stage of a campaign to search for IMBHs, in low luminosity AGN (LLAGN) and dwarf galaxies. An additional, and equally important, aim of this pilot stud…
