Gravitational wave memory of the binary black hole events in GWTC-2
Zhi-Chao Zhao, Xiaolin Liu, Zhoujian Cao +1
Gravitational wave (GW) memory is an important prediction of general relativity. Existing works on the GW memory detection focus on the waveform analysis. It is hard for waveform a…
Stochastic gravitational wave background due to gravitational wave memory
Zhi-Chao Zhao, Zhoujian Cao
Gravitational wave memory is an important prediction of general relativity, which has not been detected yet. Amounts of memory events can form a stochastic gravitational wave memor…
LTD064402+245919: A Subgiant with a 1-3 M Undetected Companion Identified from LAMOST-TD Data
Fan Yang, Bo Zhang, Richard J. Long +11
Single-line spectroscopic binaries recently contribute to the stellar-mass black hole discovery, independently of the X-ray transient method. We report the identification of a sing…
Detection of the Permanent Strain Offset Component of Gravitational-Wave Memory in Black Hole Mergers
Jeffrey D. Scargle, Zhoujian Cao, Zhi-Chao Zhao
We propose a novel approach to detecting the elusive gravitational-wave memory predicted by general relativity to accompany black hole mergers: direct measurement of the permanent…
GW200105 and GW200115 are compatible with a scenario of primordial black hole binary coalescences
Sai Wang, Zhi-Chao Zhao
Two gravitational wave events, i.e. GW200105 and GW200115, were observed by the Advanced LIGO and Virgo detectors recently. In this work, we show that they can be explained by a sc…
