Through the lens of Sgr A$^*$: identifying and resolving strongly lensed Continuous Gravitational Waves beyond the Einstein radius

Understand

Lensed gravitational waves will offer new means to probe the distribution of matter in the universe, complementary to electromagnetic signals.

• Lensed continuous gravitational waves provide new challenges and opportunities beyond those of transient compact binary coalescence.
• Here we consider continuous gravitational waves emitted by isolated neutron stars and lensed by Sgr A$^*$, the supermassive black hole at the center of our galaxy, a system observable by the next generation of gravitational wave detectors.
• We analyze the signatures of this system in detail, addressing parameter estimation and model selection.
