Constraints on a Bianchi type I spacetime extension of the standard CDM model
Ozgur Akarsu, Suresh Kumar, Shivani Sharma +1
We consider the simplest anisotropic generalization, as a correction, to the standard CDM model, by replacing the spatially flat Robertson-Walker metric by the Bianchi type-I me…
Dark sector interaction: a remedy of the tensions between CMB and LSS data
Suresh Kumar, Rafael C. Nunes, Santosh Kumar Yadav
The well-known tensions on the cosmological parameters and within the CDM cosmology shown by the Planck-CMB and LSS data are possibly due to the systematics in the d…
Testing the warmness of dark matter
Suresh Kumar, Rafael C. Nunes, Santosh Kumar Yadav
Dark matter (DM) as a pressureless perfect fluid provides a good fit of the standard CDM model to the astrophysical and cosmological data. In this paper, we investigate two exte…
