Classifying Lensed Gravitational Waves in the Geometrical Optics Limit with Machine Learning

Understand

Gravitational waves are theorized to be gravitationally lensed when they propagate near massive objects.

• Such lensing effects cause potentially detectable repeated gravitational wave patterns in ground- and space-based gravitational wave detectors.
• These effects are difficult to discriminate when the lens is small and the repeated patterns superpose.
• Traditionally, matched filtering techniques are used to identify gravitational-wave signals, but we instead aim to utilize machine learning techniques to achieve this.
