Exploring delaying and heating effects on the 21-cm signature of fuzzy dark matter
Debanjan Sarkar, Jordan Flitter, Ely D. Kovetz
In the fuzzy dark matter (FDM) model, dark matter is composed of ultra-light particles with a de Broglie wavelength of kpc, above which it behaves like cold dark matter (CDM)…
First multi-redshift limits on post-Epoch of Reionization (post-EoR) 21 cm signal from z = 1.96 - 3.58 using uGMRT
Arnab Chakraborty, Abhirup Datta, Nirupam Roy +8
Measurement of fluctuations in diffuse HI 21 cm background radiation from the post-reionization epoch (z < 6) is a promising avenue to probe the large-scale structure of the Univer…
Quantifying the Redshift Space Distortion of the Bispectrum II: Induced Non-Gaussianity at Second Order Perturbation
Arindam Mazumdar, Somnath Bharadwaj, Debanjan Sarkar
The anisotrpy of the redshift space bispectrum , which contains a wealth of cosmological information, is completely quantified using mu…
Quantifying the Redshift Space Distortion of the Bispectrum I: Primordial Non-Gaussianity
Somnath Bharadwaj, Arindam Mazumdar, Debanjan Sarkar
The anisotropy of the redshift space bispectrum contains a wealth of cosmological information. This anisotropy depends on the orientation of three vectors with…
Modelling the post-reionization neutral hydrogen () 21-cm bispectrum
Debanjan Sarkar, Suman Majumdar, Somnath Bharadwaj
Measurements of the post-reionization 21-cm bispectrum using various upcoming intensity mapping experiments hold the potential…
Redshift space distortions of the {\rm HI} 21-cm intensity mapping signal due to the internal motions within galaxies
Debanjan Sarkar, Somnath Bharadwaj
The {\rm HI} 21-cm intensity mapping signal experiences redshift space distortions due to the motion of the galaxies which contain the {\rm HI} as well as the motions of the {\rm H…
