Effects of Cloud Geometry and Metallicity on Shattering and Coagulation of Cold Gas, and Implications for Cold Streams Penetrating Virial Shocks
Zhiyuan Yao, Nir Mandelker, S. Peng Oh +2
Theory and observations reveal that the circumgalactic medium (CGM) and the cosmic web at high redshifts are multiphase, with small clouds of cold gas embedded in a hot, diffuse me…
Entrainment of Hot Gas into Cold Streams: The Origin of Excessive Star-formation Rates at Cosmic Noon
Han Aung, Nir Mandelker, Avishai Dekel +3
We explore the evolution of cold streams from the cosmic web that feed galaxies through their shock-heated circumgalactic medium (CGM) at cosmic noon, . In addition to…
Feedback-Free Starbursts at Cosmic Dawn: Observable Predictions for JWST
Zhaozhou Li, Avishai Dekel, Kartick C. Sarkar +4
We extend the analysis of a physical model within the standard cosmology that robustly predicts a high star-formation efficiency (SFE) in massive galaxies at cosmic dawn due to fee…
The Uchuu-UniverseMachine dataset: Galaxies in and around Clusters
Han Aung, Daisuke Nagai, Anatoly Klypin +7
We present the public data release of the Uchuu-UM galaxy catalogues by applying the UniverseMachine algorithm to assign galaxies to the dark matter halos in the Uchuu -body cos…
Instability of Supersonic Cold Streams Feeding Galaxies IV: Survival of Radiatively Cooling Streams
Nir Mandelker, Daisuke Nagai, Han Aung +3
We study the effects of Kelvin Helmholtz Instability (KHI) on the cold streams that feed massive halos at high redshift, generalizing our earlier results to include the effects of…
Kelvin-Helmholtz Instability in Self-Gravitating Streams
Han Aung, Nir Mandelker, Daisuke Nagai +2
Self-gravitating gaseous filaments exist on many astrophysical scales, from sub-pc filaments in the interstellar medium to Mpc scale streams feeding galaxies from the cosmic web. T…
Halo Concentrations and the New Baseline X-ray Luminosity-Temperature and Mass Relations of Galaxy Clusters
Yutaka Fujita, Han Aung
The standard self-similar model of galaxy cluster formation predicts that the X-ray luminosity-temperature (-) relation of galaxy clusters should have been $L_X\propto T_…
Instability of Supersonic Cold Streams Feeding Galaxies III: Kelvin-Helmholtz Instability in Three Dimensions
Nir Mandelker, Daisuke Nagai, Han Aung +3
We study the effects of Kelvin-Helmholtz instability (KHI) on the cold streams that feed high-redshift galaxies through their hot haloes, generalizing our earlier analyses of a 2D…
