On the consistency of CDM with CMB measurements in light of the latest Planck, ACT, and SPT data
Rodrigo Calderón, Arman Shafieloo, Dhiraj Kumar Hazra +1
Using Gaussian Processes we perform a thorough, non-parametric consistency test of the CDM model when confronted with state-of-the-art TT, TE, and EE measurements of the anisotr…
Back to the features: assessing the discriminating power of future CMB missions on inflationary models
Matteo Braglia, Xingang Chen, Dhiraj Kumar Hazra +1
Future Cosmic Microwave Background (CMB) experiments will deliver extremely accurate measurements of the E-modes pattern of the CMB polarization field. Given the sharpness of the E…
Parameter discordance in Planck CMB and low-redshift measurements: projection in the primordial power spectrum
Dhiraj Kumar Hazra, Arman Shafieloo, Tarun Souradeep
We discuss the discordance between the estimated values of the cosmological parameters from Planck assuming the concordance CDM model and low-redshift measurements. In particula…
Exploring Cosmic Origins with CORE: Inflation
CORE Collaboration, Fabio Finelli, Martin Bucher +129
We forecast the scientific capabilities to improve our understanding of cosmic inflation of CORE, a proposed CMB space satellite submitted in response to the ESA fifth call for a m…
Exploring Cosmic Origins with CORE: Cosmological Parameters
Eleonora Di Valentino, Thejs Brinckmann, Martina Gerbino +125
We forecast the main cosmological parameter constraints achievable with the CORE space mission which is dedicated to mapping the polarisation of the Cosmic Microwave Background (CM…
Search for a direction in the forest of Lyman-
Dhiraj Kumar Hazra, Arman Shafieloo
We report the first test of isotropy of the Universe in the matter dominated epoch using the Lyman- forest data from the high redshift quasars () from SDSS-III BOSS-DR9 dat…
On the scalar consistency relation away from slow roll
V. Sreenath, Dhiraj Kumar Hazra, L. Sriramkumar
As is well known, the non-Gaussianity parameter , which is often used to characterize the amplitude of the scalar bi-spectrum, can be expressed completely in terms o…
Confronting the concordance model of cosmology with Planck data
Dhiraj Kumar Hazra, Arman Shafieloo
We confront the concordance (standard) model of cosmology, the spatially flat CDM Universe with power-law form of the primordial spectrum with Planck CMB angular power spectrum…
Primordial power spectrum: a complete analysis with the WMAP nine-year data
Dhiraj Kumar Hazra, Arman Shafieloo, Tarun Souradeep
We have improved further the error sensitive Richardson-Lucy deconvolution algorithm making it applicable directly on the un-binned measured angular power spectrum of Cosmic Microw…
