Prospects for characterizing Population III remnants with next-generation gravitational-wave observatories
N. V. Krishnendu, Patricia Schmidt, Geraint Pratten
The most distant gravitational-wave (GW) detection by LIGO, Virgo and KAGRA so far is a binary black hole (BBH) merger at a redshift of , corresponding to a luminosity d…
High-Post-Newtonian-Order Dynamics Induced by Tail-of-Tail Interactions: The Non-Geodesic Terms
Geraint Pratten
We compute the tail-of-tail contribution to the conservative dynamics of eccentric, non-spinning compact binaries to relative 1PN order and to . Using the …
Strong Field Scattering of Two Black Holes: Exploring Gauge Flexibility
Adam Clark, Geraint Pratten
Recent advances in post-Minkowskian (PM) gravity provide new avenues for the high precision modeling of compact binaries. In conjunction with the effective one body (EOB) formalism…
Effect of lensing non-Gaussianity on the CMB power spectra
Antony Lewis, Geraint Pratten
Observed CMB anisotropies are lensed, and the lensed power spectra can be calculated accurately assuming the lensing deflections are Gaussian. However, the lensing deflections are…
Calabi-Yau structures on topological Fukaya categories
Vivek Shende, Alex Takeda
We develop a local-to-global formalism for constructing Calabi-Yau structures for global sections of constructible sheaves or cosheaves of categories. The required data - an isomor…
3D Weak Lensing: Modified Theories of Gravity
Geraint Pratten, Dipak Munshi, Patrick Valageas +1
Weak lensing (WL) promises to be a particularly sensitive probe of both the growth of large scale structure (LSS) as well as the fundamental relation between matter density perturb…
Galaxy Clustering in 3D and Modified Gravity Theories
Dipak Munshi, Geraint Pratten, Patrick Valageas +2
We study Modified Gravity (MG) theories by modelling the redshifted matter power spectrum in a spherical Fourier-Bessel (sFB) basis. We use a fully non-linear description of the re…
Covariant Perturbations of f(R) Black Holes: The Weyl Terms
Geraint Pratten
In this paper we revisit non-spherical perturbations of the Schwarzschild black hole in the context of gravity. Previous studies were able to demonstrate the stability of th…
Reconstructing the Thermal Sunyaev-Zel'dovich Effect in 3D
Geraint Pratten, Dipak Munshi
The thermal Sunyaev-Zel'dovich (tSZ) effect measures the line-of-sight projection of the thermal pressure of free electrons and lacks any redshift information. By cross correlating…
Effects of Linear Redshift Space Distortions and Perturbation Theory on BAOs: A 3D Spherical Analysis
Geraint Pratten, Dipak Munshi
The Baryon Acoustic Oscillations (BAO) are features in the matter power spectrum on scales of order 100-150 h^{-1} Mpc that promise to be a powerful tool to constrain and test cosm…
Non-Gaussianity in Large Scale Structure and Minkowski Functionals
Geraint Pratten, Dipak Munshi
Minkowski Functionals (MFs) are topological statistics that have become one of many standard tools used for investigating the statistical properties of cosmological random fields.…
