Accurate dust temperature determination in a $z=7.13$ galaxy

Abstract

We report ALMA Band 9 continuum observations of the normal, dusty star-forming galaxy A1689-zD1 at $z=7.13$, resulting in a $\sim$4.6$\sigma$ detection at $702$ GHz. For the first time these observations probe the far infrared (FIR) spectrum shortward of the emission peak of a galaxy in the Epoch of Reionization (EoR). Together with ancillary data from earlier works, we derive the dust temperature, $T_{\mathrm{d}}$, and mass, $M_{\mathrm{d}}$, of A1689-zD1 using both traditional modified blackbody spectral energy density fitting, and a new method that relies only on the [CII] $158\mu \mathrm{m}$ line and underlying continuum data. The two methods give $T_{\mathrm{d}}=(42_{-7}^{+13},40_{-7}^{+13}$) K, and $M_{\mathrm{d}}=(1.7_{-0.7}^{+1.3},2.0_{-1.0}^{+1.8})\times 10^7{M}_{\odot }$. Band 9 observations improve the accuracy of the dust temperature (mass) estimate by $\sim 50$% (6 times). The derived temperatures confirm the reported increasing $T_{\mathrm{d}}$-redshift trend between $z=0$ and $8$; the dust mass is consistent with a supernova origin. Although A1689-zD1 is a normal UV-selected galaxy, our results, implying that $\sim$85% of its star formation rate is obscured, underline the non-negligible effects of dust in EoR galaxies.
