CO in a Starburst Galaxy at High Z
CO in a HiZ Starburst
From Silk and Spaans ApJ 488, L79 (1997) Fig 2.: Redshift dependence of the CO
emission spectrum for a starburst galaxy containing 3 x 10^5 Orion regions.
The three red lines indicate the range in line intensities resulting from
metallicities equal to 4 and 1/4 times solar. Note the rough constancy
of line luminosity with redshift.
