Ruling out Strongly Interacting Dark Matter-Dark Radiation Models from Joint Observations of Cosmic Microwave Background and Quasar Absorption Spectra
Atrideb Chatterjee, Sourav Mitra, Amrita Banerjee
The cold dark matter (CDM) paradigm provides a remarkably good description of the Universe's large-scale structure. However, some discrepancies exist between its predictions and ob…
Predictions of the 21cm global signal in the JWST and ALMA era
Atrideb Chatterjee, Pratika Dayal, Valentin Mauerhofer
We calculate the redshift evolution of the global 21cm signal in the first billion years using a semi-analytic galaxy formation model, DELPHI, that jointly tracks the assembly of d…
Warm Dark Matter constraints from the joint analysis of CMB, Lyman-, and global 21 cm data
Atrideb Chatterjee, Tirthankar Roy Choudhury
With the help of our previously built MCMC-based parameter estimation package \texttt{CosmoReionMC}, we investigate in detail the potential of 21 cm global signal, when combined wi…
Non-parametric Reconstruction of Photon Escape Fraction from Reionization
Sourav Mitra, Atrideb Chatterjee
One of the most crucial yet poorly constrained parameters in modelling the ionizing emissivity is the escape fraction of photons from star-forming galaxies. Several theoretical and…
