Cosmological consequences of first-order general-relativistic viscous fluid dynamics
Fábio S. Bemfica, Marcelo M. Disconzi, Jorge Noronha +1
We investigate the out-of-equilibrium dynamics of viscous fluids in a spatially flat Friedmann-Lemaître-Robertson-Walker cosmology using the most general causal and stable viscous…
Ultra Long-Term Cosmology and Astrophysics
Robert J. Scherrer, Abraham Loeb
We examine astronomical observations that would be achievable over a future timeline corresponding to the documented history of human civilization so far, years. We exa…
How Slowly can the Early Universe Expand?
Robert J. Scherrer
When the expansion of the universe is dominated by a perfect fluid with equation of state parameter and a sound speed satisfying , the Hubble parameter $…
Exact general solutions for cosmological scalar field evolution in a background-dominated expansion
Robert J. Scherrer
We derive exact general solutions (as opposed to attractor particular solutions) and corresponding first integrals for the evolution of a scalar field in a universe dominated b…
Observational constraints on inflection point quintessence with a cubic potential
S. David Storm, Robert J. Scherrer
We examine the simplest inflection point quintessence model, with a potential given by . This model can produce either asymptotic de Sitter expansion or trans…
Evolution of decaying particles and decay products in various scenarios for the future expansion of the universe
Cameron E. Norton, Robert J. Scherrer
We examine nonrelativistic particles that decay into relativistic products in big rip, little rip, and pseudo-rip models for the future evolution of the universe. In contrast to de…
