Pulsar timing array observations as possible hints for nonsingular cosmology
Mian Zhu, Gen Ye, Yong Cai
Recent pulsar timing array (PTA) experiments have reported strong evidence of the stochastic gravitational wave background (SGWB). If interpreted as primordial gravitational waves…
Broken blue-tilted inflationary gravitational waves: a joint analysis of NANOGrav 15-year and BICEP/Keck 2018 data
Jun-Qian Jiang, Yong Cai, Gen Ye +1
Recently, the pulsar timing array (PTA) collaborations have reported the evidence for a stochastic gravitational wave background (SGWB) at nano-Hertz band. The spectrum of inflatio…
Can the gravitational wave background feel wiggles in spacetime?
Gen Ye, Alessandra Silvestri
Recently the international pulsar timing array collaboration has announced the first strong evidence for an isotropic gravitational wave background (GWB). We propose that rapid sma…
Shape of CMB lensing in the early dark energy cosmology
Gen Ye, Jun-Qian Jiang, Yun-Song Piao
Recently, the cosmological tensions, and in particular, have inspired modification of both pre- and postrecombination physics simultaneously. Early dark energy is a pro…
Impact of the Hubble tension on the - contour
Jun-Qian Jiang, Gen Ye, Yun-Song Piao
The injection of early dark energy (EDE) before the recombination, a possible resolution of the Hubble tension, will not only shift the scalar spectral index towards ,…
