Cosmological applications of the Brown-York quasilocal mass
Marianne Lapierre-Leonard, Valerio Faraoni, Faycal Hammad
The Brown-York quasilocal energy is applied to three cosmological problems which have previously been studied with the Hawking-Hayward quasilocal energy (Newtonian simulations of l…
Beyond lensing by the cosmological constant
Valerio Faraoni, Marianne Lapierre-Leonard
The long-standing problem of whether the cosmological constant affects directly the deflection of light caused by a gravitational lens is reconsidered. We use a new approach based…
Paczynski-Wiita-like potential for any static spherical black hole in metric theories of gravity
Valerio Faraoni, Shawn D. Belknap-Keet, Marianne Lapierre-Leonard
The pseudo-Newtonian potential of Paczynski and Wiita for particles orbiting a Schwarzschild black hole is generalized to arbitrary static and spherically symmetric spacetimes, inc…
Do Newtonian large-scale structure simulations fail to include relativistic effects?
Valerio Faraoni, Marianne Lapierre-Leonard, Angus Prain
The Newtonian simulations describing the formation of large-scale structures do not include relativistic effects. A new approach to this problem is proposed, which consists of spli…
