- W2754009941 abstract "We aim at constraining the dust mass in high-redshift ($zgtrsim 5$) galaxies using the upper limits obtained by ALMA in combination with the rest-frame UV--optical spectral energy distributions (SEDs). For SED fitting, because of degeneracy between dust extinction and stellar age, we focus on two extremes: continuous star formation (Model A) and instantaneous star formation (Model B). We apply these models to Himiko (as a representative UV-bright object) and a composite SED of $z>5$ Lyman break galaxies (LBGs). For Himiko, Model A requires a significant dust extinction, which leads to a high dust temperature $>70$ K for consistency with the ALMA upper limit. This high dust temperature puts a strong upper limit on the total dust mass $M_mathrm{d}lesssim 2times 10^6$ M$_{odot}$, and the dust mass produced per supernova (SN) $m_mathrm{d,SN}lesssim 0.1$ M$_{odot}$. Such a low $m_mathrm{d,SN}$ suggests significant loss of dust by reverse shock destruction or outflow, and implies that SNe are not the dominant source of dust at high $z$. Model B allows $M_mathrm{d}sim 2times 10^7$ M$_{odot}$ and $m_mathrm{d,SN}sim 0.3$ M$_{odot}$.} We could distinguish between Models A and B if we observe Himiko at {wavelength $<$ 1.2 mm by ALMA. For the LBG sample, we obtain $M_mathrm{d}lesssim 2times 10^6$ M$_{odot}$ for a typical LBG at $z>5$, but this only puts an upper limit for $m_mathrm{d,SN}$ as $sim 2$ M$_{odot}$. This clarifies the importance of observing UV-bright objects (like Himiko) to constrain the dust production by SNe." @default.
