JetStream: Generating Verified Query Accelerators for Existing Database Systems

Akhilesh Balasingam, Amadou Ngom, Geoffrey X. Yu +1

Recent work has shown that LLMs can synthesize highly specialized database systems for fixed workloads, but these systems replace the DBMS's native storage and assume static data:…

Fountain pattern of baryon cycle revealed in galaxy ecosystems

Chengyu Ma, Yangyao Chen, Enci Wang +11

Baryons in galaxy ecosystems are believed to undergo continuous cycles of inflow and outflow, forming fountain-like patterns that encode key information about how galaxies acquire…

Observational Evidence for Anisotropic Metal Excess around Galaxies

Cheqiu Lyu, Enci Wang, Zeyu Chen +4

The exchange of matter and energy between galaxies and their surroundings drives the cosmic baryon cycle, yet mapping metal transport remains an observational challenge. While simu…

Star formation powers optical line emission from the CGM

Huanian Zhang, Lizhi Xie, Zhijie Qu +9

Using integral field spectroscopy, we explore the disk-halo interface, or the inner circumgalactic medium (CGM), of individual galaxies by constructing and analyzing emission-line…

Environmental Imprints on the Assembly of the Cool Gas around Bright Cluster Galaxies

Runyu Zhu, Hu Zou, Taotao Fang +14

Galaxy clusters represent extreme cosmic laboratories where environmental processes dramatically reshape their constituent galaxies, yet their effect on the gaseous halos of centra…

Warped Disk Galaxies: Alignment with the Large-Scale Tidal Field

Yiheng Wang, Huiyuan Wang, Enci Wang +1

A possible origin of disk galaxy warps is the misalignment between galactic disks and their host dark matter halos, the orientations of which are found to be statistically aligned…

Cooler Phases of the Circumgalactic Medium Are More Centrally Concentrated: Constraints from Multiphase Absorption Lines

Weiwen Kong, Zeyu Chen, Enci Wang +7

We present a systematic study of the multiphase circumgalactic medium (CGM) around galaxies and quasars, traced by Ca II , Mg II , and C IV $λ…

A Universal Dance of Galactic Disks: Ubiquitous Precession and Its Implications

Yuan Wang, Xiong Luo, Huiyuan Wang +5

Precession is a very common phenomenon for small-scale astronomical objects. However, the precession of galactic disks, occurring on a scale larger than kilo-parsec, has barely bee…

The Galaxy Stellar Mass-SFR-Size Relation in EAGLE, TNG100, and Observations

Jiani Chu, Dandan Xu, Enci Wang +1

Stellar mass, size, and star formation rate (SFR) are fundamental properties that encode the structural and evolutionary states of galaxies. Observations reveal a mass-SFR-size rel…

Revisiting the Origin of the Star-Forming Main Sequence Based on a Volume-Limited Sample of ~25,000 Galaxies

Yang Gao, Shujiao Liang, Qinghua Tan +10

We revisit the extensively debated star-forming main sequence (SFMS)-a tight correlation between the star formation rate and stellar mass in both kiloparsec-resolved and integrated…

The First Systematic Survey of Stellar Halos in High-Inclination Galaxies Reveals Unusually Quiescent Merger Histories of Nearby Galaxies

Bojun Tao, Hong-Xin Zhang, Wenting Wang +8

Stellar halos are the only major stellar component of disk galaxies that lack systematic observational characterization, yet they encode critical information about galaxy merger hi…

Updated Metallicity Diagnostics for Precision Oxygen Abundance Measurements in High-redshift Galaxies with JWST

Shihong Liu, Yu Rong, Tie Li +7

Recent work has demonstrated that widely used strong-line oxygen abundance indicators, such as O3N2, , and , suffer from large uncertainties when applied…

First Statistical Detection of MgII-traced Cool Gas Outflows with JWST Towards Cosmic Dawn

Cheqiu Lyu, Haoran Yu, Enci Wang +9

Galactic-scale outflows are a crucial component of galaxy evolution, yet their properties in the early universe remain poorly constrained. We present the first statistical investig…

Stellar feedback drives the baryon deficiency in low-mass galaxies

Haoran Yu, Enci Wang, Zeyu Chen +8

Stellar feedback, as a key process regulating the baryon cycle, is thought to greatly redistribute baryonic material inside and outside the dark matter halos (DMHs), however the ob…
