Past and future isotropization in dark energy models
Adnaan Nauthoo, Peter Dunsby, Álvaro de la Cruz-Dombriz
We perform the dynamical system analysis for the homogeneous and anisotropic Bianchi I cosmology in the context of Hu-Sawicki gravity with parameters .…
Dynamical dark energy in models with evolution close to CDM
Saikat Chakraborty, Charlotte Louw, Peter K. S. Dunsby +2
In this communication we address whether or not there is an equivalence between the kinematical and dynamical descriptions of the spatially flat CDM model. We address this by in…
Power-Law Bounces in Gravity: Analysis of the Ekpyrosis and Accelerating Regimes
Saurya Das, Peter Dunsby, S. Shajidul Haque +1
We investigate the dynamics of the Friedmann-Lemaître-Robertson-Walker spacetime within the framework of gravity using a compact, model-independent dynamical systems approac…
Close Hyperbolic Encounters In f(R) Gravity
Jenna Bruton, Peter Dunsby, Alvaro de la Cruz-Dombriz
We explore the dynamics and gravitational-wave emission from black hole pairs on unbound orbits undergoing close hyperbolic encounters (CHEs) in dense astrophysical environments. W…
