Disentangling patchy reionization signatures from primordial gravitational waves using CMB -mode and -mode polarization
Divesh Jain, Suvodip Mukherjee, Tirthankar Roy Choudhury
The detection of large angular scale -mode in the Cosmic Microwave Background (CMB) polarization signal will open a direct window into not only the primary CMB anisotropies caus…
A fast method of reionization parameter space exploration using GPR trained SCRIPT
Barun Maity, Aseem Paranjape, Tirthankar Roy Choudhury
Efficient exploration of parameter spaces is crucial to extract physical information about the Epoch of Reionization from various observational probes. To this end, we propose a fa…
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…
Efficient exploration of reionization parameters for the upcoming 21 cm observations using a photon conserving semi-numerical model SCRIPT
Barun Maity, Tirthankar Roy Choudhury
One of the most promising probes to constrain the reionization history of the universe is the power spectrum of neutral hydrogen 21 cm emission fluctuations. The corresponding anal…
A Short Introduction to Reionization Physics
Tirthankar Roy Choudhury
The epoch of reionization probes the state of our universe when the very first stars formed and ionized the hydrogen atoms in the surrounding medium. Since the epoch has not yet be…
A framework to mitigate patchy reionization contamination on the primordial gravitational wave signal
Divesh Jain, Tirthankar Roy Choudhury, Suvodip Mukherjee +1
One of the major goals of future cosmic microwave background (CMB) -mode polarization experiments is the detection of primordial gravitational waves through an unbiased measurem…
