Modified theories of Gravity: Why, How and What?
S. Shankaranarayanan, Joseph P Johnson
General Relativity (GR) was proven via the direct detection of gravitational waves from the mergers of the binary black holes and binary neutron stars by the Advanced LIGO and Adva…

Cosmological perturbations in the interacting dark sector: Mapping fields and fluids
Joseph P Johnson, S. Shankaranarayanan
There is no unique way to describe the dark energy-dark matter interaction, as we have little information about the nature and dynamics of the dark sector. Hence, in many of the ph…

Low-energy modified gravity signatures on the large-scale structures
Joseph P Johnson, S. Shankaranarayanan
A large number of dark energy and modified gravity models lead to the same expansion history of the Universe, hence, making it difficult to distinguish them from observations. To m…
