-CDM: A Minimal Deformation of CDM with Scalar Field Reconstruction
Phichayoot Baisri, Nandan Roy, Prasanta Sahoo +2
Recent DESI BAO observations provide intriguing hints that dark energy may be dynamical in nature. To investigate deviations of the dark energy equation of state (EoS) from $w = -1…
CosmoDS: A Python toolkit for constraining cosmological models via dynamical systems analysis with Cobaya
Nandan Roy, Prasanta Sahoo
We present a toolkit, CosmoDS, designed to study cosmological models at the background level using dynamical system analysis within the Cobaya framework. Dynamical system analysis…
Quintom Dark Energy: Future Attractor and Phantom Crossing in Light of DESI DR2 Observation
Phusuda Thanankullaphong, Prasanta Sahoo, Prajwal Hassan Puttasiddappa +1
We study the late-time cosmological dynamics of a two-field dark energy model consisting of a canonical quintessence scalar field and a phantom scalar field in a spatially flat FLR…
