Galaxy cluster counts from eRASS1 plus weak lensing data set the tightest existing upper bounds on ultralight axion relic density Ω_a around 10^{-27} eV (Ω_a < 0.0035) and 10^{-26} eV (Ω_a < 0.0079) at 95% CL.
Joint real and redshift space analysis of CosmicFlows-4++ yields BAO scales of 132±8 h^{-1}Mpc (real) and 139±7 h^{-1}Mpc (redshift) at z=0.07 together with fσ8=0.344±0.105.
