The Limits of Photometric Dynamics: Benchmarking Cluster Relaxation Diagnostics
Alisson P. Costa, Andre L. B. Ribeiro, Zhonglue L. Wen +1
Galaxy clusters are key probes of cosmology and structure formation, yet their dynamical classification traditionally relies on spectroscopic redshifts, which do not scale efficien…
Observational Frontiers in the post-EoR 21-cm Intensity Mapping: Lessons from the SKA Pathfinders
Khandakar Md Asif Elahi, Somnath Bharadwaj, Philip Bull +21

Emulating galaxy and peculiar velocity clustering on non-linear scales
T. Dumerchat, J. Bautista, C. Ravoux +37
We explore the potential of cross-correlating galaxies and peculiar velocities on non-linear scales to enhance cosmological constraints. Leveraging the \textsc{AbacusSummit} simula…
Probing dynamical dark energy with late-time data: Evidence, tensions, and the limits of the CDM framework
Tengpeng Xu, Suresh Kumar, Yun Chen +2
We test the dynamical dark-energy CDM (CPL) framework against CDM using CMB anisotropies and lensing together with DESI DR2, SDSS-IV, transverse/angular BAO (BAOtr), and…
The DESI DR1 Peculiar Velocity Survey: growth rate measurements from the maximum likelihood fields method
Y. Lai, C. Howlett, J. Aguilar +60
We present the constraint on the growth rate of structure from the combination of DESI DR1 BGS sample, Fundamental Plane, and Tully-Fisher peculiar velocity catalogues using the ma…
Squared-field cross-correlation between kinetic Sunyaev-Zel'dovich effect and 21-cm intensity mapping
Zi-Yan Yuwen, Yu-Er Jiang, Yin-Zhe Ma +3
Neutral hydrogen (HI) 21-cm intensity mapping is an effective method to track the distribution of baryonic matter, and extract astrophysical and cosmological information. The 21-cm…
Distinguishing the nature of dark matter by mapping cosmic filaments from Lyman-alpha emission
Yizhou Liu, Liang Gao, Shihong Liao +3
The standard CDM cosmological model predicts that cosmic filaments are highly clumpy, whereas warm dark matter -- invoked to address small-scale challenges in CDM -- produces…

A high-significance detection of primordial tidal torque imprints
Ming-Jie Sheng, Hao-Ran Yu, Min Bao +8
Tidal-torque theory predicts that galaxy angular momenta are imprinted by the primordial tidal field acting on proto-structures and that they can retain information about the early…
Dynamical Dark Energy and the Unresolved Hubble Tension: Multi-model Constraints from DESI 2025 and Other Probes
Zhuoming Zhang, Tengpeng Xu, Yun Chen
We present a Bayesian comparative analysis of five cosmological models: CDM, CDM, CDM, CDM (with scalar-field dark energy), and an interacting dark energy scenario…
