Since the first gravitational-wave detecti on of a binary black hole merger in 2015\, the LIGO and Virgo detectors ha ve observed gravitational waves from more than 50 merging systems. That nu mber is expected to increase significantly over the coming years as these experiments become even more sensitive. The increased number of detections \, and the improved sensitivity of these instruments\, allows us to probe the ultra-strong regime of gravity\, as well as the formation history of t hese systems. I will discuss ongoing efforts to test general relativity in the ultra strong-field regime\, including tests of the no-hair theorem an d searches for gravitational-wave memory -- a permanent deformation of spa cetime following the passage of a gravitational wave. I will also discuss& nbsp\;efforts to detect orbital eccentricity in these systems\, which has led to potentially the first observation of a second-generation black hole merger.
