Observational Constraints on Global 21-cm Signal from the Epoch of Reionization
One of the most promising probes of Cosmic Dawn (CD) and Epoch of Reionization (EoR) is the
rest-frame global 21-cm signal of neutral hydrogen (HI) produced by the intergalactic medium (IGM)
prior to the end of the EoR ...
Morphology and topology of cosmological fields during the Epoch of Reionization
In this thesis we have introduced a real space morphological tool, Contour Minkowski
tensor (CMT) to analyse the 21cm brightness temperature field from EoR. We showed that
the size and shape information of structures ...
