The backreaction effect of the sound speed resonance in DBI inflation
Bichu Li, Chao Chen, Bo Wang
We examine the backreaction effect of the enhanced small-scale scalar perturbations from the sound speed resonance (SSR) mechanism for primordial black hole formation in Dirac-Born…
Constraining the attractive fifth force in the general free scalar-tensor gravity with solar system experiments
Xing Zhang, Bo Wang, Rui Niu
In this paper, we focus on the general free scalar-tensor gravity with three free coupling functions, which in the near-field region looks like general relativity (GR) plus a fifth…
Rapidly growing primordial black holes as seeds of the massive high-redshift JWST Galaxies
Guan-Wen Yuan, Lei Lei, Yuan-Zhu Wang +6
A group of massive galaxies at redshifts of have been recently detected by the James Webb Space Telescope (JWST), which were unexpected to form so early within the fra…
The effective field theory approach to the strong coupling issue in gravity
Yu-Min Hu, Yaqi Zhao, Xin Ren +3
We investigate the scalar perturbations and the possible strong coupling issues of around a cosmological background, applying the effective field theory (EFT) approach. We r…
Primordial black hole mass functions as a probe of cosmic origin
Yi-Fu Cai, Chengfeng Tang, Geyu Mo +7
We discuss a novel window to probe the origin of our universe via the mass functions of primordial black holes (PBHs). The mass functions of PBHs are simply estimated using the con…
