Observational constraints on interacting vacuum energy with linear interactions
Chakkrit Kaeonikhom, Hooshyar Assadullahi, Jascha Schewtschenko +1
We explore the bounds that can be placed on interactions between cold dark matter and vacuum energy, with equation of state , using state-of-the-art cosmological observations…
Qualitative dynamics of interacting vacuum cosmologies
Chakkrit Kaeonikhom, Phongsaphat Rangdee, Hooshyar Assadullahi +3
We present a phase-space analysis of the qualitative dynamics cosmologies where dark matter exchanges energy with the vacuum component. We find fixed points corresponding to power-…
Redshift-space distortion from dynamical dark energy with time-dependent Lagrangian perturbation theory
Chakkrit Kaeonikhom, Teeraparb Chantavat
We apply the Lagrangian perturbation theory with time-dependent growth functions at second and third order of perturbation with the aim to model the effect of dynamical dark energy…
Dynamics of Dirac-Born-Infeld dark energy interacting with dark matter
Chakkrit Kaeonikhom, Douglas Singleton, Sergey V. Sushkov +1
We study the dynamics of Dirac-Born-Infeld (DBI) dark energy interacting with dark matter. The DBI dark energy model considered here has a scalar field with a nonstandard kinetic e…
WMAP7 constraints on scalar-field power-law cosmology
Burin Gumjudpai, Chakkrit Kaeonikhom
In this paper, power-law cosmology whose scale factor is a power of time, $a \propto t^{\a}$, is investigated. Considering late universe with canonical scalar field and dust domina…
Observational constraints on phantom power-law cosmology
Chakkrit Kaeonikhom, Burin Gumjudpai, Emmanuel N. Saridakis
We investigate phantom cosmology in which the scale factor is a power law, and we use cosmological observations from Cosmic Microwave Background (CMB), Baryon Acoustic Oscillations…
