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…

Thermodynamics of a Non-canonical gravity
Arijit Panda, Goutam Manna, Saibal Ray +2
This work comprises a study of the thermodynamic behavior of modified gravity, which had been developed based on a non-canonical theory known as K-essence theo…
