Constraining and distortions in the Cosmic Microwave Background with COBE/FIRAS Data
Somita Dhal, Koustav Konar, R. K. Paul
This paper presents a novel approach to constrain the - and y- distortions in the Cosmic Microwave Background (CMB) using the COBE/FIRAS data. The analysis draws from the concep…

Constraining the dispersion measure redshift relation with simulation-based inference
Koustav Konar, Robert Reischke, Steffen Hagstotz +2
We use the dispersion measure (DM) of localised Fast Radio Bursts (FRBs) to constrain cosmological and host galaxy parameters using simulation-based inference (SBI) for the first t…
