Dipole Anisotropy in Integrated Linearly Polarized Flux Density in NVSS Data
Prabhakar Tiwari, Pankaj Jain
We study the dipole anisotropy in integrated linearly polarization flux density in NRAO VLA Sky Survey (NVSS). We extract the anisotropy parameters in the number counts, number cou…
Testing the Dipole Modulation Model in CMBR
Pranati K. Rath, Pankaj Jain
The hemispherical power asymmetry, observed in the CMBR data, has generally been interpreted in terms of the dipole modulation model for the temperature fluctuations. Here we point…
Dipole anisotropy in sky brightness and source count distribution in radio NVSS data
Prabhakar Tiwari, Rahul Kothari, Abhishek Naskar +2
We study the dipole anisotropy in number counts and flux density weighted number counts {or sky brightness} in the NRAO VLA Sky Survey (NVSS) data. The dipole anisotropy is expecte…
Direction dependence of the power spectrum and its effect on the Cosmic Microwave Background Radiation
Pranati K. Rath, Tanmay Mudholkar, Pankaj Jain +2
We study several anisotropic inflationary models and their implications for the observed violation of statistical isotropy in the CMBR data. In two of these models the anisotropy d…
