Dark matter (energy) may be indistinguishable from modified gravity (MOND)

Sivaram, C (World Scientific Publishing Co Pte Ltd, 2017-10)

For Newtonian dynamics to hold over galactic scales, large amounts of dark matter (DM) are required which would dominate cosmic structures. Accounting for the strong obser- vational evidence that the universe is accelerating ...
Dark matter density distributions and dark energy constraints on structure formation including MOND

Rebecca, L; Arun, K; Sivaram, C (Springer, 2020-09)

In recent papers, it was shown explicitly that the sizes of gravitationally bound large-scale cosmic structures can be constrained from the requirement that their gravitational binding self-energy density should at least ...
Dark matter, dark energy, and alternate models: A review

Arun, k; Gudennavar, S.B; Sivaram, C (Elsevier B.V, 2017-07)

The nature of dark matter (DM) and dark energy (DE) which is supposed to constitute about 95% of the energy density of the uni-verse is still a mystery. There is no shortage of ideas regarding the nature of both. While ...
Planet nine, dark matter and MOND

Sivaram, C; Arun, K; Kiren, O. V (Springer, 2016-07)

Here we propose the possibility that the recently postulated Neptune-sized planet with an orbital period of 15,000 years could be a gravitationally condensed dark matter (DM) object. The observed mass of Planet Nine fits ...
