Gravitational Wave Propagation in K-essence Cosmology: Theory and Observational Constraints
Sougata Bhunia, Eduardo Guendelman, Debashis Gangopadhyay +3
Gravitational waves (GWs) provide a powerful, theory-independent probe of the dynamical structure of spacetime and the cosmological background. We investigate the propagation of li…
Observational Insights on DBI K-essence Models Using Machine Learning and Bayesian Analysis
Samit Ganguly, Arijit Panda, Eduardo Guendelman +3
We perform a late-time cosmological study; we compare the performance of two Dirac-Born-Infeld (DBI)-type k-essence scalar field extensions of the CDM model to the standard fram…
Non-Affine Extensions of the Raychaudhuri Equation in the K-essence Framework
Samit Ganguly, Goutam Manna, Debashis Gangopadhyay +2
We present a new avenue of the Raychaudhuri Equation (RE) by introducing a non-affine parametrization within the k-essence framework. This modification accounts for non-geodesic fl…
Particle production rate for a dynamical system using the path integral approach
Samit Ganguly, Narayan Banerjee, Abhijit Bhattacharyya +1
In this work, we investigate the particle creation rate in a dynamical (Vaidya) spacetime using Feynman's path integral formalism within the framework of the effective action appro…
