SMUDGes Below the Surface: Clusters Confirm the Diversity of Low-Surface-Brightness Galaxies
Donghyeon J. Khim, Dennis Zaritsky, Loraine Sandoval Ascencio +2
We use spatially resolved Keck Cosmic Web Imager spectroscopy to study high-surface-brightness stellar components and internal kinematics in 44 low-surface-brightness galaxies from…
Systematically Measuring Ultra-Diffuse Galaxies. IX. A Gyr in the Life of Nearby Low Surface Brightness Galaxies
Dennis Zaritsky, Richard Donnerstein, Loraine Sandoval Ascencio +3
We augment the published optical photometry of ultra-diffuse galaxy candidates in the SMUDGes catalog with UV and IR measurements to investigate the recent ( Gyr) star formatio…
ID-MAGE II: The Star Forming Satellites of Low-Mass Hosts
Laura Congreve Hunter, Burçin Mutlu-Pakdil, Michael B. Farnell +14
We present results from our ongoing campaign to follow up the satellite candidates from the Identifying Dwarfs of MC Analog GalaxiEs (ID-MAGE) survey. Previously, we published a li…
Blobs and Blurs: A Citizen Science-Identified Catalog of Diffuse Galaxies in the Fornax Cluster
Nicolas Mazziotti, Michael G. Jones, Donghyeon J. Khim +2
We present a catalog of 643 diffuse galaxies identified through a citizen science search of the Fornax cluster, of which we estimate 21.8% are nucleated (139/637; 6 inconclusive).…
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…
Systematically Measuring Ultra-Diffuse Galaxies. VIII. Misfits, Miscasts, and Miscreants
Dennis Zaritsky, Richard Donnerstein, Donghyeon J. Khim
We re-examine the 7,070 candidate ultra-diffuse galaxies (UDGs) in the SMUDGes survey and provide classifications based on their visual morphology. Among the more interesting cases…
Identifying Dwarfs of MC Analog GalaxiEs (ID-MAGE): The Search for Satellites Around Low-Mass Hosts
Laura Congreve Hunter, Burçin Mutlu-Pakdil, David J. Sand +11
We present results from ID-MAGE (Identifying Dwarfs of MC Analog GalaxiEs), a survey aimed at identifying and characterizing unresolved satellite galaxies around 36~nearby LMC- and…
A Closer Look at an Unusual Ultra-Diffuse Galaxy
Donghyeon J. Khim, Dennis Zaritsky, Loraine Sandoval Ascencio +2
We present a spectroscopic study of the ``Disco Ball'' (SMDG0038365-064207), a rotationally-supported, red-sequence, ultra-diffuse galaxy (UDG) with a nuclear star cluster (NSC), m…
Caught in the Act of Quenching? -- A Population of Post-Starburst Ultra-Diffuse Galaxies
Loraine Sandoval Ascencio, M. C. Cooper, Dennis Zaritsky +3
We report the discovery of post-starburst ultra-diffuse galaxies (UDGs), identified through spectroscopic analysis with KCWI at the Keck II Telescope. Our analysis is based on a sa…
Properties of Nuclear Star Clusters in Low Surface Brightness Galaxies
Donghyeon J. Khim, Dennis Zaritsky, Mika Lambert +1
Using the SMUDGes and SDSS catalogs, and our own reprocessing of the Legacy Surveys imaging, we investigate the properties of nuclear star clusters (NSCs) in galaxies having centra…
Systematically Measuring Ultra-Diffuse Galaxies (SMUDGes). VI. Nuclear Star Clusters
Mika Lambert, Donghyeon J. Khim, Dennis Zaritsky +1
We present our photometric search for potential nuclear star clusters (NSCs) in ultra-diffuse galaxies (UDGs) as an extension of the SMUDGes catalog. We identify 325 SMUDGes galaxi…
Systematically Measuring Ultra-Diffuse Galaxies (SMUDGes). V. The Complete SMUDGes Catalog and the Nature of Ultra-Diffuse Galaxies
Dennis Zaritsky, Richard Donnerstein, Arjun Dey +5
We present the completed catalog of ultra-diffuse galaxy (UDG) candidates (7070 objects) from our search of the DR9 Legacy Survey images, including distance and total mass estimate…
An Enigmatic 380 kpc Long Linear Collimated Galactic Tail
Dennis Zaritsky, Jacob P. Crossett, Yara L. Jaffé +7
We present an intriguing, serendipitously-detected system consisting of an S0/a galaxy, which we refer to as the "Kite", and a highly-collimated tail of gas and stars that extends…
Star-Gas Misalignment in Galaxies: II. Origins Found from the Horizon-AGN Simulation
Donghyeon J. Khim, Sukyoung K. Yi, Christophe Pichon +5
There have been many studies aiming to reveal the origins of the star-gas misalignment found in galaxies, but there still is a lack of understanding of the contribution from each f…
The MAGPI Survey -- science goals, design, observing strategy, early results and theoretical framework
C. Foster, J. T. Mendel, C. D. P. Lagos +40
We present an overview of the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey, a Large Program on ESO/VLT. MAGPI is designed to study the physical dri…
Star-gas misalignment in galaxies: I. The properties of galaxies from the Horizon-AGN simulation and comparisons to SAMI
Donghyeon J. Khim, Sukyoung K. Yi, Yohan Dubois +12
Recent integral field spectroscopy observations have found that about 11% of galaxies show star-gas misalignment. The misalignment possibly results from external effects such as ga…
