Extremely Metal-Poor Galaxies in DESI DR1: Connections to Galaxies in the Early Universe
Jipeng Sui, Hu Zou, Dirk Scholte +43
Extremely Metal-Poor Galaxies (XMPGs), defined as having metallicities below 10\% of the solar value, are considered possible local analogs to primordial systems and offer a unique…
The Merian Survey: A Statistical Census of Bright Satellites of Milky Way Analogs
Yue Pan, Shany Danieli, Jenny E. Greene +10
We present a statistical census of bright, star-forming satellite galaxies around Milky Way (MW) analogs using the first data release of the Merian Survey. Our sample consists of 3…
Testing the Stellar Feedback-driven Breathing Mode in Low-mass Galaxies with Gas Kinematics
Yifei Luo, Joseph Wick, Alexie Leauthaud +7
Hydrodynamic simulations have proposed that stellar feedback and bursty star-formation can produce dark matter cores in low-mass galaxies. A key prediction is that feedback-driven…
Relationship between 2D and 3D Galaxy Stellar Mass and Correlations with Halo Mass
Conghao Zhou, Alexie Leauthaud, Shuo Xu +8
Recent studies suggest that the stars in the outer regions of massive galaxies trace halo mass better than the inner regions and that an annular stellar mass provides a low scatter…
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 galax…
