Mixing of gravitational wave echoes
Zhi-Peng Li, Yun-Song Piao
Gravitational wave (GW) echoes, if they exist, would be a probe to the near-horizon quantum structure of black hole (BH), which has motivated the searching for the echo signals in…

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…
