Satellite abundance is higher in filaments than the field by factors of 1.9-3.5, but reduced up to 79% after halo mass matching and further suppressed by dark matter tracer choice in IllustrisTNG.
FRB dispersion measures from CHIME/FRB Outrigger constrain gas mass fractions in galaxy groups and clusters, consistent with eROSITA at R500 but with mild tension at R200.
The Sloan basin of attraction is the largest gravitational basin in the local volume, spanning a diameter of ~0.13c with streamlines converging on the Sloan Great Wall, reconstructed from Cosmicflows-4 data.
Review of cosmic ray production and radio emission in galaxy clusters with recommendations for SKA observations of magnetic fields and low-energy particles.
