Distinguishing Coupled Dark Matter Dark Energy from Kinematic Phantom Crossing
Samit Ganguly, Koushik Dutta, Goutam Manna
Recent measurements of cosmic expansion have renewed interest in dark-energy scenarios in which the effective equation of state exhibits phantom-like evolution and may cross …
Observational Constraints on Gravity in the Presence of DBI-Essence Scalar Field
Mayur Mune, Praveen Kumar Dhankar, Goutam Manna +3
We investigate late-time cosmology in extended symmetric teleparallel gravity coupled to a Dirac-Born-Infeld (DBI) scalar field within gravity, where is the non-metric…
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…
Boltzmann Dynamics in K-essence Cosmology: Photon Propagation in an Emergent Spacetime
Krishnendu Roy, Debashis Gangopadhyay, Chiranjeeb Singha +1
Recent cosmological tensions, notably the Hubble and tensions, motivate extensions of the conventional FLRW framework in which additional dynamical fields can alter the eff…
