A Post-starburst Galaxy Undergoing Ram-pressure Stripping at Redshift 3.06

Mingyu Li, Zheng Cai, Bjorn H. C. Emonts +16

Understanding how galaxies ignite and extinguish their star formation remains a cornerstone question in modern astrophysics. Recent JWST surveys have revealed an overabundance of m…

(LRDs): The Low-ReDshift Little Red Dots Survey. II. DESI DR1 Sample

Xiaojing Lin, Xiaohui Fan, Zheng Cai +12

JWST has revealed a substantial population of "Little Red Dots" (LRDs) at , challenging conventional AGN frameworks. However, the low-redshift regime remains largely unexplore…

First Statistical Study of Over 100 Magnified Stellar Events at Redshift with JWST

J. M. Palencia, Fengwu Sun, J. M. Diego +25

Highly magnified stars at cosmological distances () become detectable thanks to microlensing by intracluster stars near the critical curves of galaxy clusters. Multi…

Constraining the nature of active galactic nuclei through circumgalactic Lya emission at z=2-3

Shiwu Zhang, Zheng Cai, Fabrizio Arrigoni Battaia +8

We present a comprehensive analysis of circumgalactic Lya nebulae around 59 unobscured and 26 obscured quasars at z=2-3, observed with the Keck Cosmic Web Imager (KCWI), to constra…

Deeper detection limits in astronomical imaging using self-supervised spatiotemporal denoising

Yuduo Guo, Hao Zhang, Mingyu Li +10

The detection limit of astronomical imaging observations is limited by several noise sources. Some of that noise is correlated between neighbouring image pixels and exposures, so i…

Can AI Dream of Unseen Galaxies? Conditional Diffusion Model for Galaxy Morphology Augmentation

Chenrui Ma, Zechang Sun, Tao Jing +4

Observational astronomy relies on visual feature identification to detect critical astrophysical phenomena. While machine learning (ML) increasingly automates this process, models…

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…

Oxyster: A Circumgalactic Low-ionization Oxygen Nebula next to a Starburst Galaxy at

Pengjun Lu, Mingyu Li, Dalya Baron +3

Extended emission line nebulae around galaxies or active galactic nuclei (AGNs) provide a unique window to investigate the galactic ecosystem through the circumgalactic medium (CGM…

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…
