Description
Carbon Monoxide has proven to be a well-calibrated tracer of
the total molecular gas content in galaxies at low and high
redshift. However, CO observations in galaxies of subsolar
metallicity remain challenging, even in the local universe.
For that reason, the dust mass is often used to infer the
molecular gas in low metallicity systems. I will present
first results of CO and dust measurements in the Lyman Alpha
Reference Sample (LARS), a sample of local Lyman Alpha
emitting starburst galaxies, all of subsolar metallicity.
Using multiple-J CO transitians obtained with APEX and the
IRAM 30m telescope, as well as Herschel/PACS and WISE data
in combination with physical dust models and PDR codes,
properties of the star forming gas could be derived and CO
and dust scaling relations studied.
