Primordial non-Gaussianity systematics from redshift mismatch with SPHEREx
Chandra Shekhar Saraf, David Parkinson
The ability to differentiate between different models of inflation through the imprint of primordial non-Gaussianity (PNG) requires stringent constraints on the local PNG parameter…
Cross-correlating the EMU Pilot Survey 1 with CMB lensing: Constraints on cosmology and galaxy bias with harmonic-space power spectra
K. Tanidis, J. Asorey, C. S. Saraf +8
We measured the harmonic-space power spectrum of galaxy clustering auto-correlation from the Evolutionary Map of the Universe Pilot Survey 1 data (EMU PS1) and its cross-correlatio…
Effect of redshift bin mismatch on cross correlation between DESI Legacy Imaging Survey and Planck CMB lensing potential
Chandra Shekhar Saraf, Pawel Bielewicz, Michal Chodorowski
We study the importance of precise modelling of the photometric redshift error distributions on the estimation of parameters from cross correlation measurements and present a worki…
