SI Toolbox - Full documentation
Santanu Das
SI Toolbox is a package for estimating the isotropy violation in the CMB sky. It can be used for estimating the BipoSH coefficients, Dipole modulation, and Doppler boost parameters…
Joint Bayesian analysis of large angular scale CMB temperature anomalies
Shabbir Shaikh, Suvodip Mukherjee, Santanu Das +2
Cosmic microwave background measurements show an agreement with the concordance cosmology model except for a few notable anomalies: Power Suppression, the lack of large scale power…
SIToolBox : A package for Bayesian estimation of the isotropy violation in the CMB sky
Santanu Das
The standard model of cosmology predicts a statistically isotropic (SI) CMB sky. However, the SI violation signals are always present in an observed sky-map. Different cosmological…
Progress in the Construction and Testing of the Tianlai Radio Interferometers
Santanu Das, Christopher J. Anderson, Reza Ansari +44
The Tianlai Pathfinder is designed to demonstrate the feasibility of using a wide field of view radio interferometers to map the density of neutral hydrogen in the Universe after t…
