Cold Stream Penetration of Virial Shocks: Fragmentation, Coagulation, and Disruption in the Hot Circumgalactic Medium

Zhiyuan Yao, Nir Mandelker, S. Peng Oh

Cold streams penetrating virial shocks of massive halos along cosmic web filaments are expected to fuel galaxy growth at high redshift, yet the physical processes governing their p…

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 clust…

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…

Beyond the Diffusion Coefficient: Propagators and Memory in Cosmic Ray Transport

Naixin Liang, S. Peng Oh

Cosmic ray (CR) transport is usually modeled with a single diffusion coefficient, but this description captures only the growth of the variance and not the full transport process.…

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…

Probing the Cosmic Web with Fast Radio Bursts. I. Scattering

Sharon Lapiner, Nir Mandelker, Paz Beniamini +1

We study the formation of multiphase gas in the post-accretion-shock regions of cosmic sheets, filaments, and the circumgalactic medium (CGM) of haloes, i.e., cosmic web objects (C…
