Accreting black holes (BHs) are ubiquitous in astrophysical environments involving masses between a few Msun to more than 109Msun for the most extreme supermassive BHs. They are central in explaining a range of high-energy astrophysical phenomena that we observe in our Universe, such as X-ray binaries, active galactic nuclei, and quasars. They can be not only sources of GWs, but also promissing candidates for coincident EM counterparts. As I have recently demonstrated, binary BHs in circumbinary disks can launch magnetically driven twin jets, and can potentially explain the origin of X-shaped radio galaxies.
