Observing Continuous Gravitational Waves lensed by Sgr A*


Abstract: With the rising of Gravitational Wave astronomy, observing lensed Gravitational Waves (GWs) signals in the future is a concrete possibility. The gravitational lensing of GWs provides a rich phenomenology to devise new probes of the matter distribution in the Universe. I will discuss how Continuous Gravitational Waves emitted by isolated neutron stars can be lensed by the super-massive black hole at the center of our galaxy, Sgr A*, and potentially observed by next-generation gravitational wave detectors. In particular, I will show that, with the motion of the lens taken into account, future detectors can accurately distinguish and measure parameters of lensed continuous waves from sources located behind Sgr A* within a broader area than previously considered, increasing the probability of observing such events.
