Molecular gas in low-metallicity starburst galaxies: Scaling relations and the CO-to-H${}_2$ conversion factor

Ricardo Amorín, C. Muñoz-Tuñón, J. A. L. Aguerri +1

We study the molecular content and the star formation efficiency of 21 Blue Compact Dwarfs (BCDs). We present CO(1-0) and (2-1) observations, further supplemented with additional C…
