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…
Binary Supermassive Black Holes Orbiting Dark Matter Solitons: From the Dual AGN in UGC4211 to NanoHertz Gravitational Waves
Tom Broadhurst, Chao Chen, Tao Liu +1
We explore orbital implications of the Supermassive Black Hole (SMBH) binary in UGC4211 for the energy spectrum of stochastic gravitational wave background (SGWB), measured with pu…
Growth of curvature perturbations for PBH formation \& detectable GWs in non-minimal curvaton scenario revisited
Chao Chen, Anish Ghoshal, Zygmunt Lalak +2
We revisit the growth of curvature perturbations in non-minimal curvaton scenario with a non-trivial field metric where is an inflaton field, and incorporate the effect…
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…
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…
