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…

On the kinematic and thermodynamic state of clouds in complex wind-multi-cloud environments using a Friends-of-Friends analysis
Andrei Antipov, Wladimir E. Banda-Barragán, Yuval Birnboim +3
We investigate the interaction between a shock-driven hot wind and a cold multi-cloud layer, for conditions commonly found in interstellar and circumgalactic gas. We present a meth…

Intergalactic-Absorption Confounding Circumgalactic Observations
Itai Bromberg, Kartick C. Sarkar, Orly Gnat +1
The origin of warm ions in the circum-galactic medium (CGM) surrounding massive galaxies remains a mystery. In this paper, we argue that a significant fraction of the observed warm…
