The luminosity ratio of [O\u2009iii] 88 \u03bcm (from previous campaigns) to [C\u2009ii] is 9.3 \u00b1 2.6, indicative of hard interstellar radiation fields and/or a low covering fraction of photodissociation regions. The emission of [C\u2009ii] is cospatial to the 850 \u03bcm dust emission (90 \u03bcm rest frame, from previous campaigns), however the peak [C\u2009ii] emission does not agree with the peak [O\u2009iii] emission, suggesting that the lines originate from different conditions in the interstellar medium. We fail to detect continuum emission at 1.5 mm (160 \u03bcm rest frame) down to 18 \u03bcJy (3\u03c3). This non-detection places a strong limits on the dust spectrum, considering the 137 \u00b1 26 \u03bcJy continuum emission at 850 \u03bcm. This suggests an unusually warm dust component (T \u003e 80 K, 90 per\u2009cent confidence limit), and/or a steep dust-emissivity index (\u03b2dust \u003e 2), compared to galaxy-wide dust emission found at lower redshifts (typically T \u223c 30\u201350 K, \u03b2dust \u223c 1\u20132). If such temperatures are common, this would reduce the required dust mass and relax the dust production problem at the highest redshifts. We therefore warn against the use of only single-wavelength information to derive physical properties, recommend a more thorough examination of dust temperatures in the early Universe, and stress the need for instrumentation that probes the peak of warm dust in the Epoch of Reionization.", "subitem_description_type": "Abstract"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Oxford University Press"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1093/mnras/staa509", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "This article has been accepted for publication in [Monthly Notices of the Royal Astronomical Society] \u00a9: [2020] [authors] Published by Oxford University Press on behalf of the Royal Astronomical Society.
