Modeling the HI-Halo Connection: Evolution, Scatter, and a Halo-based Prescription for 21-cm Mock Catalogs
Mohd Kamran, Gabriella De Lucia, Marta Spinelli +3
The redshifted 21-cm line of neutral hydrogen (HI) is a powerful tracer of large-scale structure, and post-reionization HI intensity mapping is emerging as a competitive cosmologic…
Probing the large-scale structure with 21cm-galaxy cross-bispectrum: Estimates from simulations and forecasts for upcoming cosmological surveys
Leon Noble, Suman Majumdar, Matteo Viel +7
The paper investigates the 21 cm–galaxy cross‑bispectrum using simulated galaxy evolution models and forecasts its detectability with upcoming Euclid‑like galaxy surveys and SKA‑Mi…
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…
The Effect of Large Optical Depths on the Non-Gaussian 21-cm signal from Cosmic Dawn
Iffat Nasreen, Kanan K. Datta, Abinash K. Shaw +6
During the Cosmic Dawn (CD), the HI 21-cm optical depth ( ) in the intergalactic medium can become significantly large. Consequently, the second and higher-order terms of …
