Interaction of massive black hole binaries with their stellar environment: I. Ejection of hypervelocity stars
A. Sesana, F. Haardt, P. Madau
We use full three-body scattering experiments to study the ejection of hypervelocity stars (HVSs) by massive black hole binaries (MBHBs) at the center of galaxies. Ambient stars dr…
