Emulating CDM-like expansion on the Phantom brane
Satadru Bag, Swagat S. Mishra, Varun Sahni
In [Schmidt PRD 80 123003 (2009)], the author suggested that dynamical dark energy (DDE) propagating on the phantom brane could mimick CDM. Schmidt went on to derive a phenomeno…
Versatile parametrization of the perturbation growth rate on the phantom brane
Alexander Viznyuk, Satadru Bag, Yuri Shtanov +1
We derive an analytical expression for the growth rate of matter density perturbations on the phantom brane (which is the normal branch of the Dvali-Gabadadze-Porrati model). This…
New tracker models of dark energy
Satadru Bag, Swagat S. Mishra, Varun Sahni
We describe a new class of dark energy (DE) models which behave like cosmological trackers at early times. These models are based on the -attractor set of potentials, originally…
Cosmological perturbations on the Phantom brane
Satadru Bag, Alexander Viznyuk, Yuri Shtanov +1
We obtain a closed system of equations for scalar perturbations in a multi-component braneworld. Our braneworld possesses a phantom-like equation of state at late times, $w_{\rm ef…
