Cosmicflows-4 Galaxy Distances
Part of the Astronomy Datasets collection on Hugging Face.
The Cosmicflows-4 (CF4) catalog is the most comprehensive compilation of galaxy distances ever assembled. Published by Tully et al. (2023), it contains 55,877 distance measurements derived from eight independent methods, enabling studies of the cosmic distance ladder, large-scale structure, and peculiar velocities of galaxies.
Dataset description
Galaxy distances are fundamental to cosmology. Unlike redshifts, which mix Hubble flow with peculiar velocities, direct distance measurements let us map the true 3D distribution of matter. CF4 consolidates distances from Type Ia supernovae, the Tully-Fisher relation, the fundamental plane, tip of the red giant branch (TRGB), Cepheid period-luminosity, surface brightness fluctuations (SBF), Type II supernovae, and maser observations.
Each entry includes the PGC galaxy identifier, coordinates (equatorial, galactic, supergalactic), CMB-frame velocity, a best-estimate distance modulus, and individual distance moduli from each method where available.
