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…
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…
