Gravitational wave scattering at : Murua construction and elliptics
Yilber Fabian Bautista, Mathias Driesse, Kays Haddad +1
We compute the amplitude for the scattering of a gravitational wave off of a spinless point particle at fourth order in Newton's constant, using the worldline quantum field theory…
Gravitational Wave Scattering in Spinless WQFT
Yilber Fabian Bautista, Mathias Driesse, Kays Haddad +1
We develop the computational framework for gravitational wave - black hole scattering in worldline quantum field theory (WQFT) without spin. Crucially, we prove on general grounds…
Jeans Model for the Shapes of Self-interacting Dark Matter Halos
Yilber Fabian Bautista, Andrew Robertson, Laura Sagunski +2
The Jeans model is a semi-analytical approach to modeling self-interacting dark matter (SIDM) that works remarkably well to reproduce the spherically-averaged halo profiles from ob…
5-Dimensional Gravitational Raman Scattering: Scalar Wave Perturbations in Schwarzschild-Tangherlini Spacetime
Samim Akhtar, Yilber Fabian Bautista, Cristoforo Iossa +1
In this Letter, we study scalar wave perturbations of arbitrary frequency to the 5D Schwarzschild-Tangherlini black hole (STBH) within general relativity. For the first time, we de…
Absorptive Effects in Black Hole Scattering
Yilber Fabian Bautista, Yu-Tin Huang, Jung-Wook Kim
In this paper we define absorptive Compton amplitudes, which captures the absorption factor for waves of spin-weight- scattering in black hole perturbation theory. At the leadin…
Post-Newtonian observables for aligned-spin binaries to sixth order in spin from gravitational self-force and Compton amplitudes
Yilber Fabian Bautista, Mohammed Khalil, Matteo Sergola +2
Accurate modeling of compact binaries is essential for gravitational-wave detection and parameter estimation, with spin being an important effect to include in waveform models. In…
Black Hole Perturbation Theory Meets CFT: Kerr Compton Amplitudes from Nekrasov-Shatashvili Functions
Yilber Fabian Bautista, Giulio Bonelli, Cristoforo Iossa +2
We present a novel study of Kerr Compton amplitudes in a partial wave basis in terms of the Nekrasov-Shatashvili (NS) function of the confluent Heun equation (CHE). Remarkably, NS-…
Dynamics for Super-Extremal Kerr Binary Systems at
Yilber Fabian Bautista
Using the recently derived higher spin gravitational Compton amplitude from low-energy analytically continued () solutions of the Teukolsky equation for the scattering of…
Scattering in Black Hole Backgrounds and Higher-Spin Amplitudes: Part II
Yilber Fabian Bautista, Alfredo Guevara, Chris Kavanagh +1
We continue to investigate correspondences between, on the one hand, scattering amplitudes for massive higher-spin particles and gravitons in appropriate quantum-to-classical limit…
Scattering Amplitude Techniques in Classical Gauge Theories and Gravity
Yilber Fabian Bautista
In this thesis we present a study of the computation of classical observables in gauge theories and gravity directly from scattering amplitudes. In particular, we discuss the direc…
Soft Constraints on KMOC Formalism
Yilber Fabian Bautista, Alok Laddha
In this note, we investigate the implications of classical soft theorems for the formalism developed by Kosower, Maybee and O'Connell (KMOC) to derive classical observables in gaug…
Post-Newtonian Waveforms from Spinning Scattering Amplitudes
Yilber Fabian Bautista, Nils Siemonsen
We derive the classical gravitational radiation from an aligned spin binary black hole on \textit{closed} orbits, using a dictionary built from the 5-point QFT scattering amplitude…
Scattering in Black Hole Backgrounds and Higher-Spin Amplitudes: Part I
Yilber Fabian Bautista, Alfredo Guevara, Chris Kavanagh +1
The scattering of massless waves of helicity in Schwarzschild and Kerr backgrounds is revisited in the long-wavelenght regime. Using a novel description of su…
On the Double Copy for Spinning Matter
Yilber Fabian Bautista, Alfredo Guevara
We explore various tree-level double copy constructions for amplitudes including massive particles with spin. By working in general dimensions, we use that particles with spins $s\…
From Scattering Amplitudes to Classical Physics: Universality, Double Copy and Soft Theorems
Yilber Fabian Bautista, Alfredo Guevara
We introduce a covariant Multipole Expansion for the scattering of a massive particle emitting photons or gravitons in dimensions. We find that these amplitudes exhibit very po…
