Unraveling the early universe's equation of state and primordial black hole production with PTA, BBN, and CMB observations
Qing-Hua Zhu, Zhi-Chao Zhao, Sai Wang +1
Pulsar timing array (PTA) data releases showed strong evidence for a stochastic gravitational-wave background in the nanohertz band. When the signal is interpreted by a scenario of…
IDECAMB: an implementation of interacting dark energy cosmology in CAMB
Yun-He Li, Xin Zhang
Interacting dark energy (IDE) scenario is a natural and important extension to the standard CDM cosmology. We develop a full numerical routine, called IDECAMB, as a patch to the…
On Measuring the 21 cm Global Spectrum of the Cosmic Dawn with an Interferometer Array
Xin Zhang, Bin Yue, Yuan Shi +2
We theoretically investigate the recovery of global spectrum (monopole) from visibilities (cross-correlation only) measured by the interferometer array and the feasibility of extra…
Model-independent measurement of cosmic curvature with the latest and SNe Ia data: A comprehensive investigation
Jing-Zhao Qi, Ping Meng, Jing-Fei Zhang +1
In the context of the discrepancies between the early and late universe, we emphasize the importance of independent measurements of the cosmic curvature in the late universe. We pr…
Joint constraints on cosmological parameters using future multi-band gravitational wave standard siren observations
Shang-Jie Jin, Shuang-Shuang Xing, Yue Shao +2
Gravitational waves (GWs) from the compact binary coalescences can be used as standard sirens to explore the cosmic expansion history. In the next decades, it is anticipated that w…
FRB dark sirens: Measuring the Hubble constant with unlocalized fast radio bursts
Ze-Wei Zhao, Ji-Guo Zhang, Yichao Li +2
Fast radio bursts (FRBs) can be used to measure cosmological parameters by employing the Macquart relation. However, at present, only a small number of FRB events are localized to…
