The Association of Molecular Gas and Natal Super Star Clusters in Henize 2–10

We present ALMA observations of the dwarf starburst galaxy He 2–10 in combination with previous SMA CO observations to probe the molecular environments of natal super star clusters (SSCs). These observations include the HCO + (1-0), HCN(1-0), HNC(1-0), and CCH(1-0) molecular lines, as well as 88 GHz continuum with a spatial resolution of ##IMG## [http://ej.iop.org/images/0004-637X/853/2/125/apjaa9ff8ieqn1.gif] {$1\buildrel{\prime\prime}\over{.} 7\times 1\buildrel{\prime\prime}\over{.} 6$} . After correcting for the contribution from free–free emission to the 88 GHz continuum flux density (∼60% of the 88 GHz emission), we derive a total gas mass for He 2–10 of ##IMG## [http://ej.iop.org/images/0004-637X/853/2/125/apjaa9ff8ieqn2.gif] {${M}_{\mathrm{gas}}=4\mbox{--}6\times {10}^{8}$} M ⊙ , roughly 5%–20% of the dynamical mass. Based on a principle component analysis, HCO + is found to be the best “genera...
