IR SED and Dust Masses of Sub-solar Metallicity Galaxies at z~2.3

Understand

We present results from ALMA 1.2mm continuum observations of a sample of 27 star-forming galaxies at z=2.1-2.5 from the MOSFIRE Deep Evolution Field (MOSDEF) survey.

• These galaxies have gas-phase metallicity and star-formation rate measurements from Hb, [OIII], Ha, and [NII].
• Using stacks of Spitzer, Herschel, and ALMA photometry (rest-frame ~ 8-400$\mu$m), we examine the IR SED of high-redshift subsolar metallicity (~0.5 $Z_{\odot}$) LIRGs.
• We find that the data agree well with an average SED template of higher luminosity local low-metallicity dwarf galaxies (reduced $\chi^2$ of 1.8).
