Probing the Baryon Distribution with Fast Radio Bursts
Manisha Caleb, Jéferson A. S. Fortunato, Steffen Hagstotz +12
Baryonic feedback redistributes matter on small to mid cosmological scales, ultimately limiting inferences from Stage IV galaxy surveys. Direct baryon tracers are crucial for recov…
Fast Radio Bursts as Cosmological Probes
Manisha Caleb, Jéferson A. S. Fortunato, Steffen Hagstotz +14
Fast radio bursts (FRBs) are brief, coherent radio pulses of extragalactic origin. They typically last from microseconds to milliseconds and have energies large enough to be visibl…
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…
Investigation on the solar spectrum using Blackbody Radiation Inversion
Koustav Konar, Kingshuk Bose, R. K. Paul
The probability distribution of temperature of a blackbody can be determined from its power spectrum. This technique is called blackbody radiation inversion. In the present paper b…
