Features in the Primordial Spectrum from WMAP: A Wavelet Analysis
Arman Shafieloo, Tarun Souradeep, P. Manimaran +2
Precise measurements of the anisotropies in the cosmic microwave background enable us to do an accurate study on the form of the primordial power spectrum for a given set of cosmol…
Spectroscopy of Cosmic topology
Tarun Souradeep
Einstein's theory of gravitation that governs the geometry of space-time, coupled with spectacular advance in cosmological observations, promises to deliver a `standard model' of c…
Measuring Statistical Isotropy of CMB Anisotropy
Tarun Souradeep, Amir Hajian, Soumen Basak
The statistical expectation values of the temperature fluctuations and polarization of cosmic microwave background (CMB) are assumed to be preserved under rotations of the sky. We…
Cosmology with CMB anisotropy
Tarun Souradeep
Measurements of CMB anisotropy and, more recently, polarization have played a very important role allowing precise determination of various parameters of the `standard' cosmologica…
Testing Global Isotropy of Three-Year Wilkinson Microwave Anisotropy Probe (WMAP) Data: Temperature Analysis
Amir Hajian, Tarun Souradeep
We examine statistical isotropy of large scale anisotropies of the Internal Linear Combination (ILC) map, based on three year WMAP data. Our study reveals no significant deviation…
Cosmological quests in the CMB sky
Tarun Souradeep
Observational Cosmology has indeed made very rapid progress in recent years. The ability to quantify the universe has largely improved due to observational constraints coming from…
