ELUCID-DESI II. Revealing dark matter mass, tidal, and velocity (MTV) fields using galaxy group phase information
Qingyang Li, Xiaohu Yang, Wensheng Hong +24
We introduce a novel method for reconstructing the cosmic mass, tidal, and velocity (MTV) fields over the redshift range using the phase information of galaxy groups.…

Closing the Observational Gap in Cosmic Dynamics: AI-Enabled Reconstruction of the Universe's Vorticity and Rotational Flow Morphology
Ziyong Wu, Xu Xiao, Fuyu Dong +7
The cosmic vorticity field, an essential tracer of nonlinear structure formation, has remained observationally inaccessible because transverse galaxy motions are difficult to measu…

A possible detection of gas rotation in galaxy groups via the kinetic Sunyaev-Zeldovich effect
Tianyi Yang, Yan-Chuan Cai, Weiguang Cui +5
We utilise the kinetic Sunyaev-Zeldovich effect (kSZ) to measure the rotation of ionised gas within galaxy groups defined in the SDSS-DR7 galaxy sample, via their dipolar imprint o…
