Cosmological analogies for geophysical flows, Lagrangians, and new analogue gravity systems
Valerio Faraoni, Sonia Jose
Formal analogies between the ordinary differential equations describing geophysical flows and Friedmann cosmology are developed. As a result, one obtains Lagrangian and Hamiltonian…
Peculiar thermal states in the first-order thermodynamics of gravity
Valerio Faraoni, Andrea Giusti, Sonia Jose +1
In the context of the recently proposed first-order thermodynamics of scalar-tensor gravity, we discuss the possibility of zero-temperature states of equilibrium other than Einstei…
When can we compute analytically lookback time, age of the universe, and luminosity distance?
Sonia Jose, Alexandre Leblanc, Valerio Faraoni
In Friedmann-Lemaître-Robertson-Walker cosmology, it is sometimes possible to compute analytically lookback time, age of the universe, and luminosity distance versus redshift, expr…
Friedmann-Lemaître-Robertson-Walker cosmology through the lens of gravitoelectromagnetism
Valerio Faraoni, Geneviève Vachon, Robert Vanderwee +1
Friedmann-Lemaître-Robertson-Walker cosmology is examined from the point of view of gravitoelectromagnetism, in the approximation of spacetime regions small in comparison with the…
The curious case of the Buchdahl-Land-Sultana-Wyman-Ibañez-Sanz spacetime
Valerio Faraoni, Sonia Jose, Alexandre Leblanc
We revisit Wyman's "other" scalar field solution of the Einstein equations and its Sultana generalization to positive cosmological constant, which has a finite 3-space and correspo…
Multi-fluid cosmology in Einstein gravity: analytical solutions
Valerio Faraoni, Sonia Jose, Steve Dussault
We review analytical solutions of the Einstein equations which are expressed in terms of elementary functions and describe Friedmann-Lemaître-Robertson-Walker universes sourced by…
