Tracking ionization balance in intergalactic medium and its implications towards metallicity
Bhaskar Arya, Kartick C. Sarkar, Shiv K. Sethi
Ionization balance in the intergalactic medium (IGM) is central to the interpretation of quasar absorption spectra, linking observed ionic columns to the underlying gas density, te…

A trailing lognormal approximation of the Lyman- forest: comparison with full hydrodynamic simulations at
Bhaskar Arya
Lyman-(Ly) forest in the spectra of distant quasars encodes the information of the underlying cosmic density field at smallest scales. The modelling of the upcoming large a…

Playground of Lognormal Seminumerical Simulations of~the~Lyman~ Forest: Thermal History of the Intergalactic Medium
Tomas Ondro, Bhaskar Arya, Rudolf Galis
This study aims to test a potential application of lognormal seminumerical simulations to recover the thermal parameters and Jeans length. This could be suitable for generating lar…
