Modification of Newtonian Gravity: Implications for Hot Gas in Clusters and Galactic Angular Momentum

Louise Rebecca, Dominic Sebastian, C Sivaram +1

In view of the negative results from various dark matter detection experiments, we had earlier proposed an alternate theoretical framework through Modification of Newtonian Gravity…

Can Hubble tension be eased by invoking a finite range for gravity?

Louise Rebecca, C Sivaram, Dominic Sebastian +1

The estimation of the Hubble constant in the past few decades has increasingly become more accurate with the advance of new techniques. But its value seems to depend on the epoch a…

MONG: An extension to galaxy clusters

Louise Rebecca, Arun Kenath, C Sivaram

The presence of dark matter, though well established by indirect evidence, is yet to be observed directly. Various dark matter detection experiments running for several years have…

The Hubble tension: Change in dark energy or a case for modified gravity?

C Sivaram, Kenath Arun, Louise Rebecca

Recently much controversy has been raised about the cosmological conundrum involving the discrepancy in the value of the Hubble constant as implied by Planck satellite observations…

Dark Energy Constraints on Masses and Sizes of Large Scale Cosmic Structures

Louise Rebecca, Kenath Arun, C Sivaram

The requirement that their gravitational binding self-energy density must at least equal the background repulsive dark energy density for large scale cosmic structures implies a ma…
