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…
The Primordial power spectrum from the largest to smallest CMB scales
Debabrata Chandra, Dhiraj Kumar Hazra, Arman Shafieloo +1
We reconstruct the primordial power spectrum (PPS) across the full range of cosmological scales accessible to Cosmic Microwave Background (CMB) observations. Using the Modified Ric…
Remembering George Smoot
John Berliner, Tom Broadhurst, Martin Bucher +31
George Smoot (1945-2025) was a major figure in observational cosmology, particularly through his role in the precision measurement of the CMB dipole and the discovery of the primor…
Reconstructing inflationary features on large scales using genetic algorithm
Alipriyo Hoory, Dhiraj Kumar Hazra, L. Sriramkumar
[Abridged] A variety of model-dependent as well as model-independent approaches suggest that certain localized features in the primordial scalar power spectrum can lead to a signif…
