Studying the morphology of HI isodensity surfaces during reionization using Shapefinders and percolation analysis
Satadru Bag, Rajesh Mondal, Prakash Sarkar +3
Minkowski functionals and Shapefinders shed light on the connectedness of large-scale structure by determining its topology and morphology. We use a sophisticated code, SURFGEN2, t…
Emulating CDM-like expansion on the Phantom brane
Satadru Bag, Swagat S. Mishra, Varun Sahni
In [Schmidt PRD 80 123003 (2009)], the author suggested that dynamical dark energy (DDE) propagating on the phantom brane could mimick CDM. Schmidt went on to derive a phenomeno…
Versatile parametrization of the perturbation growth rate on the phantom brane
Alexander Viznyuk, Satadru Bag, Yuri Shtanov +1
We derive an analytical expression for the growth rate of matter density perturbations on the phantom brane (which is the normal branch of the Dvali-Gabadadze-Porrati model). This…
The Shape and Size distribution of HII Regions near the percolation transition
Satadru Bag, Rajesh Mondal, Prakash Sarkar +2
Using Shapefinders, which are ratios of Minkowski functionals, we study the morphology of neutral hydrogen (HI) density fields, simulated using semi-numerical technique (inside-out…
