The Quintom theory of dark energy after DESI DR2
Yifu Cai, Xin Ren, Taotao Qiu +2
Observations from DESI DR2 are challenging the CDM paradigm by suggesting that the equation-of-state parameter of dark energy evolves across , a phenomenon known as the…
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…
Interpreting Pulsar Timing Array data of Gravitational Waves with Ekpyrosis-Bouncing Cosmology
Taotao Qiu, Mian Zhu
Recent pulsar timing array (PTA) experiments have reported strong evidence of the stochastic gravitational wave background (SGWB). If interpreted as primordial Gravitational Waves…
Perturbations of Mimetic Curvaton
Anxianyi Xiong, Xin-zhe Zhang, Taotao Qiu
The mimetic gravity theory is one of the interesting modified gravity theories, which aims to unify the matter component of our universe within the power of gravity. The mimetic-li…
