A Massive Galaxy at the Edge of Feedback-Free Efficiency
K. Aditya, Kartick C. Sarkar
The efficiency with which galaxies convert their available baryonic reservoir into stars sets a fundamental ceiling on stellar mass assembly in the early Universe and encodes the c…
Non-Equilibrium Ionisation in Photoionised Haloes: Implications for Shock Stability and Absorption-Line Signatures
Itai Bromberg, Kartick C. Sarkar, Orly Gnat +1
We investigate the impact of nonequilibrium ionisation (NEI) and the metagalactic radiation-field on the thermal evolution, virial shock stability, and absorption signatures of gas…
Fast modelling of ionization balance in the intergalactic medium: I- implications for the IGM 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…
