Towards a Robust Machine-Learning Pipeline for 21-cm Cosmology Data Analysis I: A Roadmap for Development and Demonstration of Robustness Against PSF Modeling Errors
Madhurima Choudhury, Jonathan C. Pober
The 21-cm signal from the Epoch of Reionization (EoR) is a powerful probe of the evolution of the Universe. However, accurate measurements of the EoR signal from radio interferomet…

Inferring IGM parameters from the redshifted 21-cm Power Spectrum using Artificial Neural Networks
Madhurima Choudhury, Raghunath Ghara, Saleem Zaroubi +8
The high redshift 21-cm signal promises to be a crucial probe of the state of the intergalactic medium (IGM). Understanding the connection between the observed 21-cm power spectrum…

Modeling of Experimentally Observed Two-Dimensional Precursor Solitons in a Dusty Plasma by the forced Kadomtsev-Petviashvili Equation
Ajaz Mir, Pintu Bandyopadhyay, Madhurima Choudhury +2
We compare model solutions of a forced Kadomtsev-Petviashvili (fKP) equation with experimental observations of dust acoustic precursor solitons excited by a supersonically moving c…
