Testing spatial curvature and anisotropic expansion on top of the CDM model

Ozgur Akarsu, Eleonora Di Valentino, Suresh Kumar +2

We explore the possible advantages of extending the CDM model by more realistic backgrounds compared to its spatially flat RW spacetime assumption, while preserving the underpin…

Relaxing cosmological tensions with a sign switching cosmological constant

Ozgur Akarsu, Suresh Kumar, Emre Ozulker +1

Inspired by the recent conjecture originated from graduated dark energy that the Universe has recently transitioned from anti-de Sitter vacua to de Sitter vacua, we extend the C…

Minimal theory of massive gravity in the light of CMB data and the tension

Jose C. N. de Araujo, Antonio De Felice, Suresh Kumar +1

We investigate the Minimal Theory of Massive Gravity (MTMG) in the light of different observational data sets which are in tension within the CDM cosmology. In particular, we an…

Remedy of some cosmological tensions via effective phantom-like behavior of interacting vacuum energy

Suresh Kumar

Since physics of the dark sector components of the Universe is not yet well-understood, the phenomenological studies of non-minimal interaction in the dark sector could possibly pa…

Reconstruction of the dark sectors' interaction: A model-independent inference and forecast from GW standard sirens

Alexander Bonilla, Suresh Kumar, Rafael C. Nunes +1

Interacting dark matter (DM) - dark energy (DE) models have been intensively investigated in the literature for their ability to fit various data sets as well as to explain some ob…
