Can the rotation of the dark matter halo of our galaxy be detected through its effect on the cosmic microwave background polarisation?
Partha Nag, Somnath Bharadwaj, Sayan Kar
The proposition that dark matter halos possess angular momentum, though widely accepted, is a theoretical prediction which has, till date, not been observationally verified. The gr…

Cosmology with decaying tachyon matter
A. Das, Shashikant Gupta, Tarun Deep Saini +1
We investigate the case of a homogeneous tachyon field coupled to gravity in a spatially flat Friedman-Robertson-Walker spacetime. Assuming the field evolution to be exponentially…

Modelling galaxy halos using dark matter with pressure
Somnath Bharadwaj, Sayan Kar
We investigate whether a dark matter with substantial amounts of pressure, comparable in magnitude to the energy density, could be a viable candidate for the constituent of dark ma…
