Extended Effective Field Theory of Dark Energy: Ghost Condensate Dark Energy with Sextic Dispersion Relation in de Sitter Spacetime
A. Ashoorioon, M. B. Jahani Poshteh, A. Yousefi-Sostani
We continue our studies of the ghost condensate (GC) with sixth-order dispersion relation. Contrary to the GC with quartic dispersion relation, we find that the correction to the N…

Particle motion and accretion disk around rotating accelerating black holes
Amjad Ashoorioon, Mohammad Bagher Jahani Poshteh, Orlando Luongo
We investigate the motion of test particles and the properties of accretion disks around rotating, accelerating black hole spacetimes with non-zero cosmological constants. To do so…
