In astrophysics, a BzK galaxy is a galaxy that has been selected as star-forming or passive based on its photometry in the B, z, and K photometric bands.

The selection criteria, as originally defined, are as follows:

  • Star-forming BzK (sBzK) galaxies satisfy: B z K ≡ ( z − K ) A B − ( B − z ) A B ≥ − 0.2
  • Passive BzK (pBzK) galaxies satisfy: B z K < − 0.2 and ( z − K ) A B > 2.5
