This process is governed by a particular light-like thermal correlator of the Energy-Momentum tensor that we study via the gauge/gravity duality. We focus on the high-energy limit, k ≫ T , and via a WKB approximation we drive an analytical solution for the energy density of emitted gravitational waves from a thermal source, obtaining a non-trivial dependency dρ 3GW ∝ ω4/3T 8/3; and for the Energy-Momentum tensor thermal correlator at arbitrary momentum5 p.application/pdfengcc-by-nc-nd (c) Fernández, 2023http://creativecommons.org/licenses/by-nc-nd/3.0/es/Ones gravitacionalsFísica de partículesTreballs de fi de grauGravitational wavesParticle physicsBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
