Morphology and topology of cosmological fields during the Epoch of Reionization

Akanksha, K (Indian Institute of Astrophysics, 2020-06)
Morphology of 21cm brightness temperature during the Epoch of Reionization using Contour Minkowski Tensor

Akanksha, K; Pravabati, C; Appleby, S (IOP Publishing, 2019-09)

We use morphological descriptors, Betti numbers and Contour Minkowski Tensor (CMT) on 21cm brightness temperature excursion sets, to study the ionization and heating history of the intergalactic medium (IGM) during and ...
A novel probe of ionized bubble shape and size statistics of the epoch of reionization using the contour Minkowski tensor

Akanksha, K; Pravabati, C; Appleby, S; Park, C (IOP Publishing, 2018-10)

We employ the rank-2 contour Minkowski tensor in two dimensions to probe length and time scales of ionized bubbles during the epoch of reionization. We demonstrate that ionized bubbles are not circular, and hence not ...
Prospects of constraining reionization model parameters using Minkowski tensors and Betti numbers

Akanksha, K; Pravabati, C; Ghara, Raghunath; Appleby, Stephen; Choudhury, T. R (IOP Publishing, 2021-05)

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