Detecting galaxies in a large H{\sc i}~spectral cube
Abinash Kumar Shaw, Manoj Jagannath, Aishrila Mazumder +4
The upcoming Square Kilometer Array (SKA) is expected to produce humongous amount of data for undertaking H{\sc i}~science. We have developed an MPI-based {\sc Python} pipeline to…
Multi-frequency angular power spectrum of the 21~cm signal from the Epoch of Reionisation using the Murchison Widefield Array
Cathryn M. Trott, Rajesh Mondal, Garrelt Mellema +5
The Multi-frequency Angular Power Spectrum (MAPS) is an alternative to spherically-averaged power spectra, and computes local fluctuations in the angular power spectrum without nee…
Redshifted 21-cm bispectrum: Impact of the source models on the signal and the IGM physics from the Cosmic Dawn
Mohd Kamran, Raghunath Ghara, Suman Majumdar +5
The radiations from the first luminous sources drive the fluctuations in the 21-cm signal at Cosmic Dawn (CD) via two dominant astrophysical processes i.e. the Ly coupling and X…
The multi-frequency angular power spectrum in parameter studies of the cosmic 21-cm signal
Rajesh Mondal, Garrelt Mellema, Steven G. Murray +1
The light-cone effect breaks the periodicity and statistical homogeneity (ergodicity) along the line-of-sight direction of cosmological emission/absorption line surveys. The spheri…
