Probing the bispectrum at high redshifts using 21 cm HI observations
Sk. Saiyad Ali, Somnath Bharadwaj, Sanjay K. Pandey
Observations of fluctuations in the redshifted 21 cm radiation from neautral hydrogen (HI) are perceived to be an important future probe of the universe at high redshifts. Under th…
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…
Testing homogeneity on large scales in the Sloan Digital Sky Survey Data Release One
J. Yadav, S. Bharadwaj, B. Pandey +1
The assumption that the universe is homogeneous and isotropic on large scales is one of the fundamental postulates of cosmology. We have tested the large scale homogeneity of the g…
What will anisotropies in the clustering pattern in redshifted 21 cm maps tell us?
Sk. Saiyad Ali, Somnath Bharadwaj, Biswajit Pandey
The clustering pattern in high redshift HI maps is expected to be anisotropic due to two distinct reasons, the Alcock-Paczynski effect and the peculiar velocities, both of which ar…
