Effects of Spin on High-Energy Radiation from Accreting Black Holes

Michael O' Riordan, Asaf Pe'er, Jonathan C. McKinney

Observations of jets in X-ray binaries show a correlation between radio power and black hole spin. This correlation, if confirmed, points towards the idea that relativistic jets ma…
