Bounce and Collapse in the Slotheonic Universe

Debabrata Adak, Amna Ali

In this paper, we examine the cosmological dynamics of a slotheon field in a linear potential. The slotheon correction term respects the galileon…

Viable dark energy models using pseudo-Nambu-Goldstone bosons

Debabrata Adak, Koushik Dutta

A canonical pseudo-Nambu Goldstone Boson (pNGB) can play the role of a dark energy field responsible for present cosmic acceleration. Confronting with the recent cosmological data,…

Late time acceleration in a slow moving galileon field

Debabrata Adak, Amna Ali, Debasish Majumdar

In this paper, we examine the cosmological viability of a slow moving galileon field in a potential. The Lagrangian $ =-\frac{1}{2}g^{μν}π_{;μ}π_{;ν} +\frac{G^{μν}}{2M^2}…

Reconstructing the equation of state and density parameter for dark energy from combined analysis of recent SNe Ia, OHD and BAO data

Debabrata Adak, Abhijit Bandyopadhyay, Debasish Majumdar

We adopt a model independent method to reconstruct the dark energy equation of state by analyzing 5 sets of SNe Ia data along with Baryon Acoustic Oscillation (BAO) and Observation…

Quintom scalar field : Varying dark energy equation of state obtained from recent SNe Ia, BAO and OHD data

Debabrata Adak, Abhijit Bandyopadhyay, Debasish Majumdar

From the analysis of Supernova Ia data alongwith Observational Hubble Data (OHD) and Baryon Acoustic Oscillation (BAO) data, we attempt to find out the nature of a scalar potential…
