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…

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…
