* Time: 11:00-12:00 * Speaker: Alvin Li (U Tokyo, RESCEU) * Title: ''"Gravitational Wave Lensing: Current Status and Future Prospects"'' * Abstract: {{{ Gravitational lensing of gravitational waves offers a unique opportunity to probe both astrophysical and cosmological phenomena, from the population properties of compact binaries to the distribution of matter in the Universe. As gravitational waves travel through the Universe, their paths can be deflected, and their amplitudes can be (de)-magnified by intervening massive structures. This leads to various observable signatures, including magnification bias, arrival time delays, and repeated signals. In this talk, I will present an overview of gravitational wave lensing, beginning with the theoretical foundations and the classification of lensing regimes relevant to ground-based detectors. I will review the status of current searches for lensed gravitational wave events, highlighting recent results from the third observing run (O3) of the LIGO-Virgo-KAGRA collaboration. In addition, I will discuss the various methods employed in lensing analyses and the challenges associated with confidently identifying lensed events. I will then outline the prospects for detecting gravitational wave lensing in upcoming observing runs and the potential scientific returns such detections could offer. I will also discuss the specific contributions KAGRA can make in making the first lensed gravitational wave detection. |

重力波研究交流会
GW research exchange meeting
Upcoming GW-REMs
The 132nd REM: Jun. 5th, 2025
- Time: 11:00-12:00
- Speaker: Alvin Li (U Tokyo, RESCEU)
Title: "Gravitational Wave Lensing: Current Status and Future Prospects"
- Abstract:
Gravitational lensing of gravitational waves offers a unique opportunity to probe both astrophysical and cosmological phenomena, from the population properties of compact binaries to the distribution of matter in the Universe. As gravitational waves travel through the Universe, their paths can be deflected, and their amplitudes can be (de)-magnified by intervening massive structures. This leads to various observable signatures, including magnification bias, arrival time delays, and repeated signals. In this talk, I will present an overview of gravitational wave lensing, beginning with the theoretical foundations and the classification of lensing regimes relevant to ground-based detectors. I will review the status of current searches for lensed gravitational wave events, highlighting recent results from the third observing run (O3) of the LIGO-Virgo-KAGRA collaboration. In addition, I will discuss the various methods employed in lensing analyses and the challenges associated with confidently identifying lensed events. I will then outline the prospects for detecting gravitational wave lensing in upcoming observing runs and the potential scientific returns such detections could offer. I will also discuss the specific contributions KAGRA can make in making the first lensed gravitational wave detection.
