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:…
Ubiquitous nuclear disks and bars embedded in massive galaxies in the cosmic morning
Jianyuan Luo, Fangzhou Jiang, Jinning Liang +8
The morphology of the central regions of high-redshift galaxies remains relatively unexplored, while recent case studies suggest that giant disks can emerge without first developin…
Reconstructing the Projected Dark Matter Field across 0.1-100 Mpc Scales from the SDSS Survey
Kunyao Zhao, Yingjie Peng, Dingyi Zhao +16
Dark matter sets the gravitational environment in which galaxies form and evolve, but cannot be observed directly. We present a conditional diffusion model that reconstructs the pr…
No Detectable One-halo Galactic Conformity Signal with Halo-mass Estimates Consistent with Weak-lensing Constraints
Dingyi Zhao, Yingjie Peng, Luis C. Ho +17
One-halo galactic conformity is the tendency for satellites in halos with quenched centrals to have lower star-formation activity than those in halos with star-forming centrals at…
Widespread Inflows Reveal Baryonic Cycling in Star-forming and Quiescent Galaxies
Hassen M. Yesuf, Ravi Joshi, Yuxuan Zou +8
Cool-gas inflows, required to sustain star formation, have been fundamental in simulations yet remained observationally elusive. Using DESI spectroscopy of ~30,000 galaxies, we ide…
The Structural Abundance Crisis of Massive Galaxies in Current Cosmological Simulations
Hassen M. Yesuf, Connor Bottrell, Luis C. Ho +5
The internal structure of galaxies encodes the complex baryon cycle driven by gas accretion, star formation, and feedback, together with secular evolution and environmentally drive…
The VariableTNG project: mass-dependent regulation of galaxy morphology by baryonic feedback
Yikai Liu, Hong Guo, Volker Springel +3
Galaxy morphology is shaped by both assembly history and baryonic processes, but their relative roles remain uncertain. We use the VariableTNG (VTNG) simulation suite to investigat…
The VariableTNG project: how baryonic mechanisms shape galaxy properties
Kexin Liu, Hong Guo, Luis C. Ho +3
We use 50 Sobol-sampled VariableTNG simulations, varying eight subgrid parameters at fixed cosmology and initial conditions, to determine which baryonic processes regulate galaxies…
The VariableTNG project: Unveiling the physical drivers of galaxy quenching
Ignacio G. Alfaro, Antonio D. Montero-Dorta, Hong Guo +4
Understanding the physical processes that regulate galaxy quenching is a key challenge in galaxy formation and evolution. The VariableTNG (VTNG) project provides a laboratory to in…
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…
Insights into the Physical Nature of Polar Ring Galaxies from H I Observations
Niankun Yu, Han Zheng, Chao-Wei Tsai +10
Polar ring galaxies (PRGs) host an outer ring of gas and stars oriented nearly perpendicular to the main stellar body. They represent extreme examples of misaligned systems and pro…
