Cosmic dawn (CD) and the epoch of reionization (EoR) are the most important parts of
cosmic history during which the first luminous structures emerged. These first objects heated …

Detecting the cosmic 21-cm signal during the Epoch of Reionization and Cosmic Dawn will
reveal insights into the properties of the first galaxies and advance cosmological parameter …

ABSTRACT The upcoming Square Kilometre Array Observatory will produce images of
neutral hydrogen distribution during the epoch of reionization by observing the …

Enlightening our understanding of the first galaxies responsible for driving reionization
requires detecting the 21-cm signal from neutral hydrogen. Interpreting the wealth of …

The distribution of ionized hydrogen during the epoch of reionization (EoR) has a complex
morphology. We propose to measure the 3D topology of ionized regions using the Betti …

We present measurements of the Minkowski functionals extracted from the SDSS-III BOSS
catalogs. After defining the Minkowski functionals, we describe how an unbiased …

We explore the possibility of constraining model parameters of the Epoch of Reionization
(EoR) from 21cm brightness temperature maps, using a combination of morphological …

We study the topology of the network of ionized and neutral regions that characterized the
intergalactic medium during the Epoch of Reionization. Our analysis uses the formalism of …

High-redshift 21-cm observations will provide crucial insights into the physical processes of
the Epoch of Reionization. Next-generation interferometers such as the Square Kilometer …

Detecting the 21-cm hyperfine transition from neutral hydrogen in the intergalactic medium is
our best probe for understanding the astrophysical processes driving the Epoch of …
