The Merian Survey: A Statistical Census of Bright Satellites of Sub-Milky Way-Mass Galaxies
Lucas S. Mandacarú Guerra, Jiaxuan Li, Yue Pan +9
Satellite populations provide sensitive tests of the galaxy-halo connection, but studies have largely focused on Milky Way (MW)-mass host galaxies or a small number of nearby dwarf…
ELVES-Dwarf. II. A Systematic Search for Satellite Systems of Dwarf Galaxies in the Local Volume

We present the Exploration of Local VolumE Satellites of Dwarf Galaxies (ELVES-Dwarf) survey, a systematic census of satellite systems around dwarf hosts in the Local Volume. Our f…
The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Satellite Galaxies
Jonah C. Rose, Mariangela Lisanti, Paul Torrey +24
We analyze the properties of satellite galaxies around 1,024 Milky Way-mass hosts from the DREAMS Project, simulated within a CDM cosmology. Utilizing the TNG galaxy-formation m…
Zangetsu: A Candidate of Isolated, Quiescent, and Backsplash Ultra-Diffuse Galaxy in the COSMOS Field
Leyao Wei, Song Huang, Jiaxuan Li +3
Deep imaging surveys have changed our view of the low surface brightness (LSB) Universe. The ``renaissance'' of the LSB galaxy population, as a prime example of this recent develop…
ELVES-Dwarf I: Satellites Systems of Eight Isolated Dwarf Galaxies in the Local Volume
Jiaxuan Li, Jenny E. Greene, Shany Danieli +4
The satellite populations of Milky Way--mass systems have been extensively studied, significantly advancing our understanding of galaxy formation and dark matter physics. In contra…
Diversity and universality: evolution of dwarf galaxies with self-interacting dark matter
Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +4
Dark matter halos with self-interacting dark matter (SIDM) experience a unique evolutionary phenomenon, in that their central regions eventually collapse to high density through th…
Merian: A Wide-Field Imaging Survey of Dwarf Galaxies at z~0.06-0.10
Shany Danieli, Erin Kado-Fong, Song Huang +32
We present the Merian Survey, an optical imaging survey optimized for studying the physical properties of bright star-forming dwarf galaxies. Merian is carried out with two medium-…
A Nonparametric Morphological Analysis of H Emission in Bright Dwarfs Using the Merian Survey
Abby Mintz, Jenny E. Greene, Erin Kado-Fong +10
Using medium-band imaging from the newly released Merian Survey, we conduct a nonparametric morphological analysis of H emission maps and stellar continua for a sample of galaxi…
The HI reservoir in central spiral galaxies and the implied star formation process
Jing Dou, Yingjie Peng, Qiusheng Gu +14
The cold interstellar medium (ISM) as the raw material for star formation is critical to understanding galaxy evolution. It is generally understood that galaxies stop making stars…
Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc
Jiaxuan Li, Jenny E. Greene, Scott G. Carlsten +1
It is well-known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy…
Constraining Protoplanetary Disk Winds from Forbidden Line Profiles with Simulation-based Inference
Ahmad Nemer, ChangHoon Hahn, Jiaxuan Li +2
Protoplanetary disks are the sites of vigorous hydrodynamic processes, such as accretion and outflows, and ultimately establish the conditions for the formation of planets. The pro…
PopSED: Population-Level Inference for Galaxy Properties from Broadband Photometry with Neural Density Estimation
Jiaxuan Li, Peter Melchior, ChangHoon Hahn +1
We present PopSED, a framework for the population-level inference of galaxy properties from photometric data. Unlike the traditional approach of first analyzing individual galaxies…
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 Merian Survey: Design, Construction, and Characterization of a Filter Set Optimized to Find Dwarf Galaxies and Measure their Dark Matter Halo Properties with Weak Lensing
Yifei Luo, Alexie Leauthaud, Jenny Greene +28
The Merian survey is mapping 850 degrees of the Hyper Suprime-Cam Strategic Survey Program (HSC-SSP) wide layer with two medium-band filters on the 4-meter Victor M. Bla…
Beyond Ultra-diffuse Galaxies. II. Environmental Quenching of Mass-Size Outliers among the Satellites of Milky Way Analogs
Jiaxuan Li, Jenny E. Greene, Johnny Greco +5
Recent observations have reignited interest in a population of dwarf galaxies that are large and diffuse for their mass, often called ultra-diffuse galaxies. However, the origin an…
ELVES III: Environmental Quenching by Milky Way-Mass Hosts
Jenny E. Greene, Shany Danieli, Scott Carlsten +3
Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are often devoid of young stars, even in Milky Way-mass groups. Dwarf galaxies thus offer…
The Nature of Low Surface Brightness Galaxies in the Hyper Suprime-Cam Survey
Jenny E Greene, Johnny P. Greco, Andy D. Goulding +9
We present the statistical redshift distribution of a large sample of low surface brightness (LSB) galaxies identified in the first 200 deg of the Hyper Suprime-Cam Strategic S…
Cold Gas in Massive Galaxies as A Critical Test of Black Hole Feedback Models
Jingjing Shi, Yingjie Peng, Benedikt Diemer +15
Black hole feedback has been widely implemented as the key recipe to quench star formation in massive galaxies in modern semi-analytic models and hydrodynamical simulations. As the…
