Dynamics of tachyon dark energy on large scales and its imprint on observed galaxy power spectrum

Ajay Bassi, Ankan Mukherjee, Anjan A. Sen

In the present work, we study the large scale matter power spectrum as well as the observed galaxy power spectrum for non-canonical tachyon field dark energy model considering the…

Dark Energy with Phantom Crossing and the tension

Eleonora Di Valentino, Ankan Mukherjee, Anjan A. Sen

We investigate the possibility of phantom crossing in the dark energy sector and solution for the Hubble tension between early and late universe observations. We use robust combina…

Observational Constraints on Axion(s) Dark Energy with a Cosmological Constant

Ruchika, Shahnawaz A. Adil, Koushik Dutta +2

The present work deals with a dark energy model that has an oscillating scalar field potential along with a cosmological constant (CC). The oscillating part of the potential repres…

New physics in decays with complex Wilson coefficients

Aritra Biswas, Soumitra Nandi, Ipsita Ray +1

We perform a data-driven analysis of new physics (NP) effects in exclusive decays in a model-independent effective theory approach with dimension six operato…
