Beyond CDM: Problems, solutions, and the road ahead
Philip Bull, Yashar Akrami, Julian Adamek +37
Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, CDM. This is motivated by a range o…
Integration of inhomogeneous cosmological spacetimes in the BSSN formalism
James B. Mertens, John T. Giblin, Glenn D. Starkman
We present cosmological-scale numerical simulations of an evolving universe in full general relativity (GR) and introduce a new numerical tool, {\sc CosmoGRaPH}, which employs the…
Departures from the FLRW Cosmological Model in an Inhomogeneous Universe: A Numerical Examination
John T. Giblin, James B. Mertens, Glenn D. Starkman
While the use of numerical general relativity for modeling astrophysical phenomena and compact objects is commonplace, the application to cosmological scenarios is only just beginn…
CMB Anomalies after Planck
Dominik J. Schwarz, Craig J. Copi, Dragan Huterer +1
Several unexpected features have been observed in the microwave sky at large angular scales, both by WMAP an by Planck. Among those features is a lack of both variance and correlat…
Hidden Ward-Takahashi identities in the spontaneously brokenAbelian Higgs model and the decoupling of certain heavy particles in its simple extensions
Bryan W. Lynn, Glenn D. Starkman
This work is dedicated to the memory of R. Stora. The spontaneously broken (SSB) Abelian Higgs model (AHM) (the gauge theory of a scalar $ϕ\propto (H+iπ)= {\tilde H}e^{i{\…
Global linear sigma model: axial-vector Ward Takahashi identities, and decoupling of certain heavy BSM particles due to the Goldstone theorem
Bryan W. Lynn, Glenn D. Starkman
Dedicated to the memory of Raymond Stora (1930-2015). In the Linear Sigma Model with PCAC, towers of Ward-Takahashi Identities (WTI) have long been known to…
