Here's a summary of the paper:

"To date, black holes remain among the most enigmatic objects in our universe. Thanks to gravitational wave detections, we have taken significant steps toward “illuminating” their hidden structure. However, the wealth of information contained in these signals is far from fully explored. With the precision of the upcoming LISA mission, we may gain access to gravitational waves from black hole mergers that probe the interface between gravity and quantum phenomena. In particular, we show that the so-called echo effect—repeated wave signals from a single merger, arriving at Earth with short time delays—could be detectable by LISA for sufficiently strong events. Encoded within these echoes is potentially profound information, offering new insights into the quantum aspects of black holes and the fundamental nature of spacetime."
