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.
Simulations show SPHEREx photometry is generally unbiased but source blending drives outliers; with brightness selection, photometric redshifts reach σ_NMAD ≈ 0.003-0.01 and cluster redshifts are recovered to |Δz|/(1+z) < 0.002 at z ≲ 0.5.
