Swampland diagnostics and observational tests of the inflationary universe in the Palatini formalism
Saeed Noori Gashti, Mohammad Reza Alipour, Mohammad Ali S. Afshar +1
We consider quintessential inflation in a quadratic Palatini model with a generalized Peebles-Vilenkin potential, where the same scalar field describes both the inflationary platea…

Reconstruction of a dark energy model for the Dirac-Born-Infeld scalar field with the Hubble and DESI data via Gaussian process
Sayantan Ghosh, Gaurav N. Gadbail, P. K. Sahoo +1
In this study, we reconstruct the dark energy (DE) as a Dirac-Born-Infeld (DBI) scalar field from the Hubble dataset (32 CC + 26 BAO) and the DESI dataset using the Gaussian proces…
