Cosmological Signatures of Curvature-Coupled Dark Energy
Abdolali Banihashemi, Farbod Hassani, Alessandro Casalino +2
We study a curvature-coupled dark energy model that can modify cosmological evolution both before recombination and during the late-time accelerated era. The model belongs to the c…
On the (higher multipoles) variance asymmetry in the cosmic microwave background
MohammadHossein Jamshidi, Abdolali Banihashemi, Nima Khosravi
We have studied the cosmic microwave background (CMB) map looking for features beyond cosmological isotropy. We began by tiling the CMB variance map (which are produced by differen…
Local Limit of Nonlocal Gravity: Cosmological Perturbations
Javad Tabatabaei, Abdolali Banihashemi, Shant Baghram +1
We explore the cosmological implications of the local limit of nonlocal gravity, which is a classical generalization of Einstein's theory of gravitation within the framework of tel…
Anisotropic Cosmology in the Local Limit of Nonlocal Gravity
Javad Tabatabaei, Abdolali Banihashemi, Shant Baghram +1
Within the framework of the local limit of nonlocal gravity (NLG), we investigate a class of Bianchi type I spatially homogeneous but anisotropic cosmological models. The modified…
Dynamic Dark Energy from the Local Limit of Nonlocal Gravity
Javad Tabatabaei, Abdolali Banihashemi, Shant Baghram +1
Nonlocal gravity (NLG), a classical extension of Einstein's theory of gravitation, has been studied mainly in linearized form. In particular, nonlinearities have thus far prevented…
Fluctuations in the Ginzburg-Landau Theory of Dark Energy: internal (in-)consistencies in PLANCK data set
Abdolali Banihashemi, Nima Khosravi
In this work, predictions of the Ginzburg-Landau theory of dark energy (GLT) for CMB lensing are studied. We find that the time and scale dependence of the dark energy fluctuations…
Dark Energy as a Critical Phenomenon: a Resolution for Hubble Tension
Abdolali Banihashemi, Nima Khosravi, Arman Shafieloo
We propose a dark energy model based on the physics of critical phenomena which is consistent with both the Planck's CMB and the Riess et al.'s local Hubble measurements. In this m…
Ginzburg-Landau Theory of Dark Energy: A Framework to Study Both Temporal and Spatial Cosmological Tensions Simultaneously
Abdolali Banihashemi, Nima Khosravi, Amir H. Shirazi
A dark energy model (DE) is proposed based on Ginzburg-Landau theory of phase transition (GLT). This model, GLTofDE, surprisingly provides a framework to study not only temporal te…
Ups and Downs in Dark Energy: phase transition in dark sector as a proposal to lessen cosmological tensions
Abdolali Banihashemi, Nima Khosravi, Amir H. Shirazi
Based on tensions between the early and late time cosmology, we proposed a double valued cosmological constant which could undergo a phase transition in its history. It is named "d…
