Late-time acceleration and structure formation in interacting -attractor dark energy models
L. K. Duchaniya, B. Mishra, G. Otalora +1
We investigate the cosmological dynamics of interacting dark energy within the framework of -attractor models. Specifically, we analyze the associated autonomous system, focusi…
Cosmological and Dynamical Aspects of Teleparallel Gravity and its Extension
L K Duchaniya
This thesis investigates the characteristics of modified teleparallel gravity models that incorporate a scalar field and a trace of the energy-momentum tensor, with particular atte…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Late Time Phenomena in Gravity Framework: Role of Priors
L. K. Duchaniya, B. Mishra
This study explored the behavior of the cosmological model with the use of various data set combinations. We also compared the results for this model between th…
Quintessence model in the late Universe
L. K. Duchaniya, Jackson Levi Said, B. Mishra +1
Scalar fields have shown great potential in inducing tailored modifications compared to cosmic evolution in the CDM model. We investigate a quintessence model with five physical…
The scalar-torsion gravity corrections in the first-order inflationary models
I. V. Fomin, S. V. Chervon, L. K. Duchaniya +1
The corrections to the cosmological models induced by non-minimal coupling between scalar field and torsion are considered. To determine these corrections in explicit form, the pow…
