Constraining exotic dark matter models with the dark ages 21-cm signal
Rajesh Mondal, Rennan Barkana, Anastasia Fialkov
The dark ages 21-cm signal is a powerful tool for precision cosmology and probing new physics. We study two non-standard models: an excess radio background (ERB) model (possibly ge…
POLAR -- I: linking the 21-cm signal from the epoch of reionization to galaxy formation
Qing-Bo Ma, Raghunath Ghara, Benedetta Ciardi +5
To self-consistently model galactic properties, reionization of the intergalactic medium, and the associated 21-cm signal, we have developed the algorithm polar by integrating the…
SKA Science Data Challenge 2: analysis and results
P. Hartley, A. Bonaldi, R. Braun +105
The Square Kilometre Array Observatory (SKAO) will explore the radio sky to new depths in order to conduct transformational science. SKAO data products made available to astronomer…
Interpreting the HI 21-cm cosmology maps through Largest Cluster Statistics -- I: Impact of the synthetic SKA1-Low observations
Saswata Dasgupta, Samit Kumar Pal, Satadru Bag +7
We analyse the evolution of the largest ionized region using the topological and morphological evolution of the redshifted 21-cm signal coming from the neutral hydrogen distributio…
Studying the Multi-frequency Angular Power Spectrum of the Cosmic Dawn 21-cm Signal
Abinash Kumar Shaw, Raghunath Ghara, Saleem Zaroubi +5
The light-cone (LC) anisotropy arises due to cosmic evolution of the cosmic dawn 21-cm signal along the line-of-sight (LoS) axis of the observation volume. The LC effect makes the…
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…
