Cylindrical Gravitational Wave: Source and Resonance

Yu-Zhu Chen, Shi-Lin Li, Yu-Jie Chen, Wu-Sheng Dai
2021 Symmetry  
The first kind of singularity corresponds to a singular source. The second kind of singularity corresponds to a resonance between different gravitational waves.  ...  When two gravitational waves coexist, the interference term in the source may vanish in the sense of time averaging.  ...  Two gravitational waves with sources and two gravitational waves without sources do not resonate with one another.  ...

Cylindrical gravitational waves: radiation and resonance [article]

Yu-Zhu Chen, Yu-Jie Chen, Shi-Lin Li, Wu-Sheng Dai
2020 arXiv   pre-print
In this paper, we present an exact general solution of the cylindrical gravitational wave. The exact solution of the cylindrical gravitational wave is far different from the weak field approximation.  ...  This solution implies the following conclusions. (1) There exist gravitational monopole radiations in the cylindrical gravitational radiation. (2) The gravitational radiation may generate the resonance  ...  This work is supported in part by Nankai Zhide foundation and NSF of China under Grant No. 11575125 and No. 11675119.  ...

Cylindrical Gravitational Waves in Expanding Universes: Explicit Pulse Solutions [article]

Robert H. Gowdy
2007 arXiv   pre-print
Solutions analogous to the Weber-Wheeler cylindrical pulse waves are found for the case of cylindrical gravitational waves in an expanding universe.  ...  These pulse solutions mimic the asymptotic properties of waves from an isolated source in three dimensions and can be used to test the far-field behavior of numerical simulation techniques.  ...  The waves are cylindrical, which accounts for spreading in two dimensions.  ...

2006 Journal of Physics, Conference Series  
Resonant detectors are now sensitive to the strongest potential sources of gravitational waves in our galaxy and in the local group.  ...  The status of the 4 operating cylindrical gravitational waves resonant antenna detectors is summarized. A short review is given of the experimental results and of the next generation projects.  ...  The experimental search for gravitational waves was initiated by Joseph Weber in the early 60. His detector was very similar to the modern cylindrical resonant bar detectors.  ...
