Finding the distribution of matter using lenses - II: deconvolution-based reconstruction with 3x2pt measurements
Jun-Qian Jiang, Ajoy Dawn, Dhiraj Kumar Hazra +2
We present a deconvolution-based framework for testing scale-dependent departures of the late-time matter power spectrum from a fiducial cosmological model using pt measu…

Finding the distribution of matter using lenses - I: deconvolution-based reconstruction with CMB lensing
Ajoy Dawn, Jun-Qian Jiang, Dhiraj Kumar Hazra +2
The matter power spectrum is one of the primary statistical descriptors of the large-scale distribution of matter in the Universe and provides a powerful probe of cosmic structure…
