Searching for gravitational wave echoes in GWTC-1 and O3 events
Yu-Tong Wang, Yun-Song Piao
Gravitational wave (GW) echoes, if they exist, would be a probe to the near-horizon physics of black hole. In this brief report, we performed the Monte Carlo Markov Chain analysis…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
On echo intervals in gravitational wave echo analysis
Yu-Tong Wang, Jun Zhang, Shuang-Yong Zhou +1
Gravitational wave echoes, if they exist, could encode important information of new physics from the strong gravity regime. Current echo searches usually assume constant interval e…
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…
