Investigating the Origin of CMB Large-Scale Features Using LiteBIRD and CMB-S4
Catherine Petretti, Matteo Braglia, Xingang Chen +2
Several missions following Planck are currently under development, which will provide high-precision measurements of the Cosmic Microwave Background (CMB) anisotropies. Specificall…
Exploring the discrepancy between Planck PR3 and ACT DR4
Dhiraj Kumar Hazra, Benjamin Beringue, Josquin Errard +2
We explore the scales and the extent of disagreement between PR3 and Atacama Cosmology Telescope (ACT) DR4 data. and ACT data have substantial overlap in the temp…
The asymmetry of dawn: evidence for asymmetric reionization histories from a joint analysis of cosmic microwave background and astrophysical data
Daniela Paoletti, Dhiraj Kumar Hazra, Fabio Finelli +1
We show that by jointly fitting cosmic microwave background (CMB) and astrophysical data - a compilation of UV luminosity data from the Hubble Frontier Field and neutral hydrogen d…
Model-independent Reconstruction of UV Luminosity Function and Reionization Epoch
Debabrata Adak, Dhiraj Kumar Hazra, Sourav Mitra +1
We conduct a first comprehensive study of the Luminosity Function (LF) using a non-parametric approach. We use Gaussian Process to fit available luminosity data between redshifts $…
A search for super-imposed oscillations to the primordial power spectrum in Planck and SPT-3G 2018 data
Akhil Antony, Fabio Finelli, Dhiraj Kumar Hazra +2
We search for super-imposed oscillations linearly or logarithmically spaced in Fourier wavenumbers in Planck and South Pole Telescope (SPT-3G) 2018 temperature and polarization…
