Testing Isotropy of Cosmic Microwave Background Radiation
Pramoda Kumar Samal, Rajib Saha, Pankaj Jain +1
We introduce new symmetry-based methods to test for isotropy in cosmic microwave background radiation. Each angular multipole is factored into unique products of power eigenvectors…
CMB anisotropy power spectrum using linear combinations of WMAP maps
Rajib Saha, Simon Prunet, Pankaj Jain +1
In recent years the goal of estimating different cosmological parameters precisely has set new challenges in the effort to accurately measure the angular power spectrum of CMB. Thi…
Circumventing Astrophysical Bounds Upon PVLAS Experiment
Subhayan Mandal, Pankaj Jain
We study the possibility of evading astrophysical bound on light pseudoscalars. We argue that the solar bounds can be evaded if we have a sufficiently strong self-coupling of the p…
Cosmological Symmetry Breaking, Pseudo-scale invariance, Dark Energy and the Standard Model
Pankaj Jain, Subhadip Mitra
The energy density of the universe today may be dominated by the vacuum energy of a slowly rolling scalar field. Making a quantum expansion around such a time dependent solution is…
