Primordial gravastar from inflation
Yu-Tong Wang, Jun Zhang, Yun-Song Piao
The dS bubbles can nucleate spontaneously during inflation, and will be stretched by the cosmological expansion to astrophysical scale. We report on a novel phenomenon that such a…

Are gravitational wave ringdown echoes always equal-interval ?
Yu-Tong Wang, Zhi-Peng Li, Jun Zhang +2
Gravitational wave (GW) ringdown waveforms may contain "echoes" that encode new physics in the strong gravity regime. It is commonly assumed that the new physics gives rise to the…

Phase-transition sound of inflation at gravitational waves detectors
Yu-Tong Wang, Yong Cai, Yun-Song Piao
It is well-known that the first-order phase transition (PT) will yield a stochastic gravitational waves (GWs) background with a logo-like spectrum. However, we show that when such…
