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…

Probing Reionization up to the Mark: The Marked Power Spectrum to unveil the HI 21-cm signal from the EoR
Vishrut Pandya, Leon Noble, Suman Majumdar +3
The redshifted 21-cm signal from neutral hydrogen (HI) in the intergalactic medium (IGM) is a powerful probe of the Epoch of Reionization (EoR). Owing to the complex growth and mor…
