Oscillons during Dirac-Born-Infeld Preheating
Yu Sang, Qing-Guo Huang
Oscillons are long-lived, localized, oscillating nonlinear excitations of a real scalar field which can be abundantly produced during preheating after inflation. We give the first…
Gravitational waves induced by the local-type non-Gaussian curvature perturbations
Chen Yuan, Qing-Guo Huang
The current observational constraints still leave a substantial mass window for primordial black holes (PBHs) representi…
Hubble constant and sound horizon from the late-time Universe
Xue Zhang, Qing-Guo Huang
We measure the expansion rate of the recent Universe and the calibration scale of the baryon acoustic oscillation (BAO) from low-redshift data. BAO relies on the calibration scale,…
The three body first post-Newtonian effects on the secular dynamics of a compact binary near a spinning supermassive black hole
Yun Fang, Qing-Guo Huang
The binary black holes (BBHs) formed near the supermassive black holes (SMBHs) in the galactic nuclei would undergo eccentricity excitation due to the gravitational perturbations f…
Scalar Induced Gravitational Waves in Different Gauges
Chen Yuan, Zu-Cheng Chen, Qing-Guo Huang
In this letter we calculate the scalar induced gravitational waves (SIGWs) accompanying the formation of primordial black hole during the radiation dominated era in three different…
