Even central galaxies feel their environment: cosmic siphoning of cool gas accretion
Ke Xu, Tao Wang
The paper investigates how the environment of central galaxies influences their cool gas accretion, proposing a multi‑scale “cosmic siphoning” process where massive halos and centr…
Satellite quenching by radio jets of central galaxies in galaxy groups
Yijun Wang, Tao Wang, Dingyi Zhao +9
Feedback from active galactic nuclei (AGN) is now recognized as a key component of galaxy formation models. It plays a central role in regulating the growth and quenching of galaxi…
A Bending in the Size-mass Relation of Star-forming Galaxies across at a Critical Stellar Mass of Revealed by JWST
Longyue Chen, Tao Wang, Hanwen Sun +12
We investigate the rest-frame optical size-stellar mass relation of galaxies at using deep JWST/NIRCam and MIRI imaging from the PRIMER survey. We find that star-formin…
Speed by Simplicity: A Single-Stream Architecture for Fast Audio-Video Generative Foundation Model
SII-GAIR, Sand. ai, : +43
We present daVinci-MagiHuman, an open-source audio-video generative foundation model for human-centric generation. daVinci-MagiHuman jointly generates synchronized video and audio…
Cosmic Vine: High abundance of massive galaxies and dark matter halos in a forming cluster at z=3.44
Nikolaj B. Sillassen, Shuowen Jin, Georgios E. Magdis +10
The Cosmic Vine is a massive protocluster at z=3.44 in the JWST CEERS field, offering an ideal laboratory for studying the early phases of cluster formation. Using the data from th…
Ly-alpha emission reveals two satellite halos around massive groups at z ~ 3: the puzzling case of a quiescent central galaxy
Sicen Guo, Emanuele Daddi, Raphael Gobat +17
We present the discovery and characterisation of two Ly nebulae (LANs), RO-1001-Sat and RO-0959-Sat, as satellite structures of two giant LANs at and 3.092. They are…
