How much do turbulence, bulk motions, shocks, and other non-thermal components violate hydrostatic support and bias cluster masses?

Scientific question index
The index lists active nodes only; superseded questions remain as historical pages with successor links.
Which high-redshift galaxy populations and heating or ionization processes shape the cosmic-dawn 21-cm signal, and can present observations distinguish them?
Q-COSMIC-DAWN-IDENTIFIABILITY
How do stellar and AGN feedback couple energy, momentum, and metals to the multiphase ISM/CGM and regulate outflows and recycling?
Q-FEEDBACK-MULTIPHASE-COUPLING
How do feedback and environment set the radial thermodynamic structure and retained hot-baryon fraction of galaxy halos over time?
Q-GALAXY-HOT-HALO-INVENTORY-EVOLUTION
How does the observed hot-baryon distribution across halos differ from that required by the baryon-census and pressure-support budgets?
Q-HOT-BARYON-BUDGET-SUPPORT
How are stellar nucleosynthetic products transported and mixed through the ISM, CGM, and ICM while preserving a recoverable enrichment history?
Q-METAL-TRANSPORT-MIXING
How are high-energy particles accelerated, escaped, and transported through compact sources, galaxies, and diffuse media to produce discriminating non-thermal emission?
Q-NONTHERMAL-PARTICLE-TRANSPORT
How is cold gas transported from halo and galactic scales to SMBHs, and how does feedback close an observable self-regulation cycle?
Q-SMBH-FUELING-FEEDBACK-CYCLE
