Field-level large-scale structure meets the CMB
CSiBORG–Manticore simulations of the local Universe are compared with CMB thermal Sunyaev–Zel'dovich measurements: the simulations recover galaxy clusters at the right positions and with the right halo masses.

A 1.8% measurement of the Hubble constant from Cepheids alone
A new Cepheid-only distance ladder yields H₀ = 71.7 ± 1.3 km/s/Mpc, reinforcing the Hubble tension without relying on supernovae.
