Observational Evidence for the Kinematic Memory of Cosmic Filaments from Satellite Orbital Orientations

Peng Wang, Wei Wang, Wenting Wang +5

We present an observational study of the kinematic coherence between satellite orbital planes and the cosmic web. Using the SDSS DR12 galaxy sample combined with the Bisous filamen…

Unveiling the Sources of X-ray Luminosity in DESI Galaxy Groups: Insights from the SRG/eROSITA All-Sky Survey

YunLiang Zheng, Xiaohu Yang, Teng Liu +10

We use the first eROSITA all-sky survey (eRASS1) to investigate the contributions of AGN and extended gas to the total X-ray luminosity () of galaxy groups with different halo…

Unveiling the galactic baryon cycle process by an empirical model

Yaoxin Chen, Xi Kang, Hong Guo +2

We propose an empirical model to describe and constrain the baryon cycle process during galaxy evolution. This model utilizes the evolution of star formation rate, derived from the…

Observed Anti-parallel Correlation Between Spiral Galaxy and Cosmic Filament Spins

Hao-da Wang, Peng Wang, Min Bao +7

Understanding the origin of galactic angular momentum and its connection to the cosmic web remains a pivotal issue in galaxy formation. Using kinematic data from the MaNGA survey,…

Causal Discovery in Astrophysics: Unraveling Supermassive Black Hole and Galaxy Coevolution

Zehao Jin, Mario Pasquato, Benjamin L. Davis +9

Correlation does not imply causation, but patterns of statistical association between variables can be exploited to infer a causal structure (even with purely observational data) w…

NIHAO-RiNG: A Comparison of Simulated Disc Galaxies from GASOLINE and GIZMO

Hou-Zun Chen, Xi Kang, Andrea V. Macciò +2

We utilize the public GIZMO code to simulate twelve disc galaxies from the NIHAO suite simulated with the GASOLINE code, then compare the corresponding galaxies in the two simulati…
