Observational Signatures of Mass-Loading in Jets Launched by Rotating Black Holes

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

It is widely believed that relativistic jets in X-ray binaries and active-galactic nuclei are powered by the rotational energy of black holes. This idea is supported by general-rel…

The X-ray counterpart to the gravitational wave event GW 170817

E. Troja, L. Piro, H. van Eerten +31

A long-standing paradigm in astrophysics is that collisions- or mergers- of two neutron stars (NSs) form highly relativistic and collimated outflows (jets) powering gamma-ray burst…
