Cold Stream Penetration of Virial Shocks: Fragmentation, Coagulation, and Disruption in the Hot Circumgalactic Medium
Zhiyuan Yao, Nir Mandelker, S. Peng Oh
The paper uses 3D hydrodynamic simulations to study how cold gas streams interact with the hot circumgalactic medium of massive halos, identifying regimes of coagulation, fragmenta…
Star Formation Histories and Stellar Dynamics in the Central Galaxies of RX J0820.9+0752, A1835, and PKS 0745-191
Marie-Joëlle Gingras, B. R. McNamara, Alison L. Coil +5
We present Keck Cosmic Web Imager observations of stellar populations in three galaxies lying at the centers of cooling flow clusters. All three host rich molecular gas reservoirs…
Clumps in a Cocoon: Geometry and Mixing Set the Universal X-ray to H Surface Brightness Ratio
Zirui Chen, S. Peng Oh, Drummond B. Fielding +3
Recent observations reveal a universal X-ray to H surface-brightness ratio, , in galactic winds, ram-pressure stripped tails, and clu…
The (Limited) Effect of Viscosity in Multiphase Turbulent Mixing
Tirso Marin-Gilabert, Max Gronke, S. Peng Oh
Multiphase gas can be found in many astrophysical environments, such as galactic outflows, stellar wind bubbles, and the circumgalactic medium, where the interplay between turbulen…
A Dynamical Test for Cooling-Induced Entrainment in a Runaway Supermassive Black Hole Tail
Ish Kaul, S. Peng Oh
Radiative turbulent mixing layers are widely invoked to explain the survival, growth, and entrainment of cold gas in hot astrophysical flows, but quantitative dynamical tests have…
From Clumps to Sheets: Geometry Controls the Temperature PDF of Multi-Phase Gas
Zirui Chen, S. Peng Oh
Temperature probability distribution functions (PDFs) are a compact description of the thermal structure of multi-phase turbulent gas, and are directly linked to observables such a…
