Cosmology with Multi-Wavelength Line Intensity Mapping Synergies in the SKAO Era

Debanjan Sarkar, Suman Majumdar, Chandra Shekhar Murmu +21

Line intensity mapping (LIM) has emerged as a powerful tool for surveying the large-scale structure of the Universe across cosmic time by measuring spatial fluctuations in the cumu…

Cosmology with Intensity Mapping via Statistics Beyond the Power Spectrum in the SKAO Era

Suman Majumdar, Debanjan Sarkar, Leon Noble +38

The cosmological distribution of neutral hydrogen (HI) during the post-reionization era is highly non-Gaussian due to the underlying non-linear structure formation, complex galaxy…

From ANN to BNN: Inferring Reionization Parameters using Uncertainty-aware Emulators of 21-cm Summaries

Yashrajsinh Mahida, Sanjay Kumar Yadav, Suman Majumdar +6

Inferring astrophysical parameters from radio interferometric observations of the redshifted 21-cm signal from the Epoch of Reionization (EoR) is a challenging yet crucial task. Th…
