Gravitational Effects of Weak Interactions at TeV Energies
C Sivaram, Kenath Arun
Recently there has been a lot of interest in the search for extra dimensions. If gravity propagates in extra dimensions then gravity would become as strong as other interactions. T…
Some Enigmatic Aspects of the Early Universe III
C Sivaram, Kenath Arun
In the previous parts of the discussion on the same topic, various aspects of the very early universe were discussed. We discussed how inclusion of large dark energy term compensat…
Some Enigmatic Aspects of the Early Universe II
C Sivaram, Kenath Arun, Venkata Manohara Reddy A
In a recent paper it was suggested that inclusion of mutual gravitational interactions among the collapsing particles can avert a singularity and give finite value for various phys…
Some Additional Bounds on the Photon Charge
C. Sivaram, Kenath Arun
We have arrived at tight constraints on the photon charge, giving comparable bounds, one based on the dominance by dark energy at the present epoch, and the other based on the requ…
Some Aspects of Intermediate mass black holes
C. Sivaram, Kenath Arun
There is a lot of current astrophysical evidence and interest in intermediate mass black holes, ranging from a few hundred to several thousand solar masses. The active galaxy M82 a…
