Why are we still using 3D masses for cluster cosmology?

Kavli Affiliate: Salman Habib | First 5 Authors: Stijn N. B. Debackere, Henk Hoekstra, Joop Schaye, Katrin Heitmann, Salman Habib | Summary: The abundance of clusters of galaxies is highly sensitive to the late-time evolution of the matter distribution, since clusters form at the highest density peaks. However, the 3D cluster mass cannot be inferred […]

Infrared Finite Scattering Theory in Quantum Field Theory and Quantum Gravity

Kavli Affiliate: Robert M. Wald | First 5 Authors: Kartik Prabhu, Gautam Satishchandran, Robert M. Wald, , | Summary: Infrared (IR) divergences arise in scattering theory with massless fields and are manifestations of the memory effect. There is nothing singular about states with memory, but they do not lie in the standard Fock space. IR […]

Modified gravitational wave propagation with higher modes and its degeneracies with lensing

Kavli Affiliate: Wayne Hu | First 5 Authors: Jose Maria Ezquiaga, Wayne Hu, Macarena Lagos, Meng-Xiang Lin, Fei Xu | Summary: Low-energy alternatives to General Relativity (GR) generically modify the phase of gravitational waves (GWs) during their propagation. As detector sensitivities increase, it becomes key to understand how these modifications affect the GW higher modes […]
