Can gravitational waves get gravitationally lensed? The first ever detection of this might have just happened. This is especially cool because if we could routinely measure lensing of gravitational waves, we could use that to measure all sorts of other important things like the Hubble constant and precision tests of gravity to name just two. One of the interesting things you will hear about in today’s talk is an improved modeling of the candidate lens. This better nails down the probability that the wave really was lensed and even more fun gives insight into what astrophysical things the source and lens could be. In today’s talk, we’re joined by Miguel Zumalacarregui from the Max Plank Institute for Gravitational Physics in Potsdam, Germany to tell us about his new paper.
