Merger rate of supermassive primordial black hole binaries
Hai-Long Huang, Jun-Qian Jiang, Yun-Song Piao
The probability that the primordial black hole (PBH) binaries formed in the early Universe can be affected by the Hubble expansion of background, which is non-negligible when the n…
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…
Supermassive primordial black holes in multiverse: for nano-Hertz gravitational wave and high-redshift JWST galaxies
Hai-Long Huang, Yong Cai, Jun-Qian Jiang +2
Recently, observational hints for supermassive black holes have been accumulating, which has inspired ones to wonder: Can primordial black holes (PBHs) be supermassive, in particul…
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 ,…
