Dark Energy in the DESI Era: A Brief Review of Evidence, Beyond-CDM Interpretations, and Tensions
Tian-Nuo Li, Guo-Hong Du, Hao Wang +3
The paper reviews recent DESI BAO measurements that hint at dynamical dark energy and examines various beyond‑ΛCDM scenarios and their implications for cosmological tensions like t…
Robust Preference for Dark Sector Interactions
Tian-Nuo Li, William Giarè, Guo-Hong Du +4
The paper investigates whether interactions between dark matter and dark energy can explain recent DESI BAO observations, finding strong statistical evidence for such interactions…
Two-Dimensional Pulsar Distance Inference from Nanohertz Gravitational Waves
Si-Ren Xiao, Ji-Yu Song, Yue Shao +3
Pulsar timing arrays (PTAs) are limited in localizing nanohertz continuous gravitational waves (CGWs) by uncertainties in pulsar distances. We introduce a method to infer pulsar di…
Phase transitions in scalarized topological AdS black holes
Zi-Qiang Zhao, Zhang-Yu Nie, Shao-Wen Wei +2
We investigate the behavior of black hole scalarization induced by a charged scalar field in the extended phase space of the asymptotic AdS spacetime with three distinct horizon to…
Model-independent late-universe measurements of and with the parametrization based on cosmic age-improved inverse distance ladder
Guo-Hong Du, Tian-Nuo Li, Jia-Le Ling +3
The standard model has encountered serious challenges and the tension has become more significant with increasingly precise cosmological observations. Meanwhile,…
Identifying lensed gravitational waves with physics-informed posterior learning
Tian-Yang Sun, Xiao Guo, Jing-Fei Zhang +1
Gravitational lensing of gravitational waves can probe compact lenses, dark matter substructure, and cosmological distances, but identifying lensed events is difficult when unrelat…
