Bounce Inflation with Dynamical Dark Energy in Light of DESI DR2
Xin-zhe Zhang, Hao-Hao Li, Taotao Qiu
Recently, the Dark Energy Spectroscopic Instrument Data Release 2 (DESI DR2) suggests that the dark energy in our universe might be evolving, favoring the Chevallier-Polarski-Linde…

Do JWST reionization (optical depth) puzzle, cosmological tensions, and CMB anomalies imply Harrison-Zel'dovich spectrum?
Hao-Hao Li, Xin-zhe Zhang, Taotao Qiu +1
The James Webb Space Telescope (JWST) has observed massive galaxies at high redshifts, which implies an earlier epoch of reionization (EoR) compared with the cosmic microwave backg…

Primordial Bounce-Inflation Scenario to Alleviate Cosmological Tensions and Lensing Anomaly
Hao-Hao Li, Xin-zhe Zhang, Taotao Qiu
We put forward a primordial scenario to alleviate cosmological tensions, i.e. Hubble () tension and tension. Based on flat CDM, the Bounce-Inflation (BI) scenario g…
