N2 - In a previous paper [H. Raj and R. Venugopalan, Phys. Rev. D 109, 044064 (2024)PRVDAQ2470-001010.1103/PhysRevD.109.044064], we demonstrated a double-copy relation between inclusive gluon radiation in shock wave collisions of ultrarelativistic nuclei and inclusive graviton radiation in trans-Planckian gravitational shock wave collisions. We compute here the corresponding gravitational shock wave propagators in general relativity and demonstrate that they too obey a double-copy relation to gluon shock wave propagators computed previously. These results provide key input in a renormalization group approach toward computing the high frequency radiation spectrum in close black hole encounters.
