Exact Integrable CDM-Mimicking Cosmology: Background, Stability, and Perturbations in the First Connection Branch
Wompherdeiki Khyllep, Daniele Gregoris, Saikat Chakraborty +1
We re-examine the problem of mimicking the standard cosmological model, characterized by (where is the cosmographic jerk parameter), within the context of the first conne…
A Unified Dynamical Systems Framework for Cosmology in Gravity: Generic Features Beyond the Coincident Gauge
Jibitesh Dutta, Wompherdeiki Khyllep, Saikat Chakraborty +2
We present a unified dynamical systems framework for spatially flat FLRW cosmology in gravity, covering all three connection branches via a single set of Hubble-normalised v…
Reproducing CDM-like Solutions in Gravity: A Comprehensive Study Across All Connection Branches
Saikat Chakraborty, Jibitesh Dutta, Daniele Gregoris +2
Given the remarkable success of the CDM model in fitting various cosmological observations, a pertinent question in assessing the phenomenological viability of modified gravity…
Stiff fluid spike solutions from Bianchi type V seed solutions
Daniele Gregoris, Woei Chet Lim, Alan Coley
In this paper we expand upon our previous work [1] by using the entire family of Bianchi type V stiff fluid solutions as seed solutions of the Stephani transformation. Among the ne…
