Tachyonic vs Quintessence dark energy: linear perturbations and CMB data
Manvendra Pratap Rajvanshi, Avinash Singh, H. K. Jassal +1
We use linear perturbation theory to study perturbations in dynamical dark energy models. We compare quintessence and tachyonic dark energy models with identical background evoluti…
Perturbations in Tachyon Dark Energy and their Effect on Matter Clustering
Avinash Singh, H. K. Jassal, Manabendra Sharma
A non-canonical scalar tachyon field is a viable candidate for dark energy and has been found to be in good agreement with observational data. Background data alone cannot complete…
Low redshift observational constraints on tachyon models of dark energy
Avinash Singh, Archana Sangwan, H. K. Jassal
The background evolution of an accelerated, dark energy dominated universe is aptly described by non-canonical tachyon scalar field models. The accelerated expansion of the univers…
