Complete analysis of the background and anisotropies of scalar-induced gravitational waves: primordial non-Gaussianity and considered
Jun-Peng Li, Sai Wang, Zhi-Chao Zhao +1
Investigation of primordial non-Gaussianity holds immense importance in testing the inflation paradigm and shedding light on the physics of the early Universe. In this study, we co…
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…
Unveiling the Graviton Mass Bounds through Analysis of 2023 Pulsar Timing Array Data Releases
Sai Wang, Zhi-Chao Zhao
Strong evidence for the Helling-Downs correlation curves have been reported by multiple pulsar timing array (PTA) collaborations in middle 2023. In this work, we investigate the gr…
Constraints On Scalar-Induced Gravitational Waves Up To Third Order From Joint Analysis of BBN, CMB, And PTA Data
Sai Wang, Zhi-Chao Zhao, Qing-Hua Zhu
Recently, strong evidence for a gravitational wave background has been reported by collaborations of pulsar timing arrays (PTA). In the framework of scalar-induced gravitational wa…
Implications of Pulsar Timing Array Data for Scalar-Induced Gravitational Waves and Primordial Black Holes: Primordial Non-Gaussianity Considered
Sai Wang, Zhi-Chao Zhao, Jun-Peng Li +1
Multiple pulsar-timing-array collaborations have reported strong evidence for the existence of a gravitational-wave background. We study physical implications of this signal for co…
Primordial Non-Gaussianity and Anisotropies in Scalar-Induced Gravitational Waves
Jun-Peng Li, Sai Wang, Zhi-Chao Zhao +1
Primordial non-Gaussianity encodes vital information of the physics of the early universe, particularly during the inflationary epoch. To explore the local-type primordial non-Gaus…
