The Non-universal Pseudo Phase-Space Density Profiles of Symphony Host Halos
Bocheng Feng, Ethan O. Nadler, S. Peng Oh +1
Cosmological N-body simulations have long suggested that the pseudo phase-space density (PPSD), , of cold dark matter haloes follows the universal relation $ρ/σ^3 \propto r^…
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…
Modeling Emission-Line Surface Brightness in a Multiphase Galactic Wind: An O VI Case Study
Zirui Chen, Zixuan Peng, Kate H. R. Rubin +6
We present a fast and robust analytic framework for predicting surface brightness (SB) of emission lines in galactic winds as a function of radius up to kpc out in the c…
: Self-Sustained Streaming Motions in Multi-Phase MHD
Chaoran Wang, S. Peng Oh, Yan-Fei Jiang +1
Radiative cooling can drive dynamics in multi-phase gas. A dramatic example is hydrodynamic `shattering', the violent, pressure-driven fragmentation of a cooling cloud which falls…
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…
Velocity Structure Correlations between the Nebular, Molecular, and Atmospheric Gases in the Cores of Four Cool Core Clusters
Muzi Li, B. R. McNamara, Alison L. Coil +6
We investigate the velocity structure of nebular gas in the central galaxies of four clusters: Abell 1835, PKS 0745-191, Abell 262, and RXJ0820.9+0752, using data from the Keck Cos…
