Updated Nearby Galaxy Catalog with 869 Galaxies within 11 Mpc

An all-sky catalog of 869 nearby galaxies within 11 megaparsecs or with specific radial velocities relative to the Local Group. The catalog, a renewed version of a 2004 work, contains observables like diameters, magnitudes, and fluxes, and derived parameters like masses and environmental indices. This table was created by NASA's HEASARC in June 2013 based on data from the Astronomical Journal.

Use Cases

• Analyzing the Hubble flow and galaxy scaling relations based on distance estimates and radial velocities.
• Studying galaxy structure and star formation using derived parameters like stellar mass, H I mass, and surface brightness.
• Quantifying the local density environment of galaxies using the provided 'tidal index' parameters.
• Investigating the mass distribution within the Local Volume using calculated indicative masses and rotational velocities.

Strengths

• Catalog contains 869 galaxies with individual distance estimates.
• Includes both direct observables and multiple calculated global parameters like masses and environmental indices.
• Explicitly lists 108 dwarf galaxies without measured radial velocities, highlighting data gaps.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known (869), but the number of features per row is unspecified.
• Last updated 2026-03-13 17:50:29.517664; freshness should be verified as the underlying data is from 2013.
