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.…
Towards Testable Type-III Leptogenesis in Non-Standard Early Universe Scenarios
Simran Arora, Devabrat Mahanta
Leptogenesis is an elegant way to explain the baryon asymmetry of the Universe in connection to the neutrino mass and mixing. Although leptogenesis from the decay of a heavy Majora…
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…
Dynamical dark energy parameterizations in VCDM
Simran Arora, Antonio De Felice, Shinji Mukohyama
In the context of a theory of minimally modified gravity called VCDM, one can realize any cosmological behavior at the level of the homogeneous and isotropic background without int…
Interacting Scalar Fields as Dark Energy and Dark Matter in Einstein scalar Gauss Bonnet Gravity
Saddam Hussain, Simran Arora, Yamuna Rana +2
A Gauss-Bonnet (GB) coupled scalar field , responsible for the late-time cosmic acceleration and interacting with a coherent scalar field through an interaction potential $W…
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…
Interacting Models of Dark Energy and Dark Matter in Einstein scalar Gauss Bonnet Gravity
Saddam Hussain, Simran Arora, Yamuna Rana +2
We study the dynamics of the interacting models between the Gauss-Bonnet (GB) coupled scalar field and the dark matter fluid in a homogeneous and isotropic background. A key featur…
