BzK galaxy
Appearance
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,[1] are as follows:
- Star-forming BzK (sBzK) galaxies satisfy:
- Passive BzK (pBzK) galaxies satisfy: and
