DOI: 10.1088/1475-7516/2018/01/051
Abstract: The standard model of cosmology with nearly Gaussian, isotropic, scale invariant and adiabatic initial conditions describes the cosmological observations well. However, the study of any deviation from the mentioned conditions will open up a new… read more here.

DOI: 10.1088/1475-7516/2023/04/063
Abstract: The gravitational lensing distortion of Cosmic microwave background radiation (CMB) carries fruitful information of cosmic large-scale structure. However, CMB observations are unavoidably contaminated by emission from various extra-galactic foregrounds, which must be removed to obtain… read more here.

DOI: 10.1093/mnras/stw2482
Abstract: We present results from cross-correlating Planck CMB lensing maps with the Sloan Digital Sky Survey (SDSS) galaxy lensing shape catalog and BOSS galaxy catalogs. For galaxy position vs. CMB lensing cross-correlations, we measure the convergence… read more here.

DOI: 10.1093/mnras/stz2922
Abstract: We present cosmological parameter constraints based on a joint modelling of galaxy–lensing cross-correlations and galaxy clustering measurements in the SDSS, marginalizing over small-scale modelling uncertainties using mock galaxy catalogues, without explicit modelling of galaxy bias.… read more here.
