Data-Driven Discovery of a Simple Phantom-Crossing Dark Energy Parametrization
Giulia Borghetto, Ameek Malhotra, Simran Arora +4
We develop a data-driven reconstruction programme for the dark-energy equation of state within VCDM, a minimally modified gravity framework in which both background and linear pert…
Does DESI prefer Damped Oscillating Dark Energy over Cosmological constant?
Saddam Hussain, Simran Arora, Qiang Wu +1
We investigate a dark-energy equation of state governed by a damped harmonic oscillator equation, admitting underdamped, critically damped, and overdamped solutions. Confronting th…
Constraining Spatial Curvature with Priors from Swampland Conjectures
Simran Arora, Hun Jang, Shinji Mukohyama
We study a string-motivated theoretical prior on the quintessential dark energy model with exponential potential, \( V(ϕ) = V_0 e^{-λϕ} \), allowing for non-zero spatial curvature.…
Interacting bosonic dark energy and fermionic dark matter in Einstein scalar Gauss-Bonnet gravity
Simran Arora, Saddam Hussain, Benjamin Rose +1
We explore a cosmological framework in which a Gauss-Bonnet (GB) coupled scalar field, acting as dark energy, interacts with a fermionic dark matter field through a coupling obtain…
Probing the Dynamics of Gaussian Dark Energy Equation of State Using DESI BAO
Saddam Hussain, Simran Arora, Anzhong Wang +1
We present an updated reconstruction of the DE equation of state (EoS), , employing the newly released DESI DR2 Baryon Acoustic Oscillation data. This analysis constrains the…
