Cosmological solutions with charged black holes

The cosmological tree theorem
(Springer, 2023-12-12)A number of diagrammatic “cutting rules” have recently been developed for the wavefunction of the Universe which determines cosmological correlation functions. These leverage perturbative unitarity to relate particular ... -
Cosmologies with Energy Exchange
We provide a simple mathematical description of the exchange of energy between two fluids in an expanding Friedmann universe with zero spatial curvature. The evolution can be reduced to a single non-linear differential ... -
Cosmology and fundamental physics with the Euclid satellite

Cosmology with Phase 1 of the Square Kilometre Array Red Book 2018: Technical specifications and performance forecasts
(Astronomical Society of Australia, 2020)We present a detailed overview of the cosmological surveys that we aim to carry out with Phase 1 of the Square Kilometre Array (SKA1) and the science that they will enable. We highlight three main surveys: a medium-deep ... -
Cosmology Without Averaging
We construct cosmological models consisting of large numbers of identical, regularly spaced masses. These models do not rely on any averaging procedures, or on the existence of a global Friedmann-Robertson-Walker (FRW) ... -
Counting Tensor Model Observables and Branched Covers of the 2-Sphere
(2014-02-04)Lattice gauge theories of permutation groups with a simple topological action (henceforth permutation-TFTs) have recently found several applications in the combinatorics of quantum field theories (QFTs). They have been ... -
Cross Helicity Reversals in Magnetic Switchbacks

Cross-section measurements for the production of a Z boson in association with high-transverse-momentum jets in pp collisions at √s = 13 TeV with the ATLAS detector
(Springer, 2023-06-14)Cross-section measurements for a Z boson produced in association with high-transverse-momentum jets (p T ≥ 100 GeV) and decaying into a charged-lepton pair (e + e − , μ + μ −) are presented. The measurements are performed ...
