Tidal effects on radiation in gravitational shockwave collisions
Isabelle Blackstad, Himanshu Raj, Raju Venugopalan
We compute high frequency gravitational wave radiation in shockwave collisions of a light mass compact object with energy off a heavy compact object (black hole) with energy…
Squeezed-state radiation in shockwave scattering: QCD-Gravity double copy
