• W3214962017 abstract "We have obtained 1 and 3 mm spectral scans of ASXDF1100.053.1 using NOEMA. ASXDF1100.053.1 is an unlensed optically dark millimetre-bright SMG with $K_{rm AB}>25.7$ ($2sigma$), which was expected to lie at $z=$5-7 based on its radio-submm photo-$z$. Our data detected line emission due to $^{12}$CO($J=$5-4) and ($J=$6-5), providing a $z_{rm CO}= 5.2383pm0.0005$. Energy-coupled SED modelling indicates properties of $L_{rm IR}=8.3^{+1.5}_{-1.4}times10^{12}$ L$_{odot}$, SFR $=630^{+260}_{-380}$ M$_{odot}$ yr$^{-1}$, $M_{rm dust}=4.4^{+0.4}_{-0.3}times10^{8}$ M$_{odot}$, $M_{rm stellar}=3.5^{+3.6}_{-1.4}times10^{11}$ M$_{odot}$, and $T_{rm dust}=37.4^{+2.3}_{-1.8}$ K. The CO luminosity allows us to estimate a gas mass $M_{rm gas}=3.1pm0.3times10^{10}$ M$_{odot}$, suggesting a gas-to-dust mass ratio of around 70, fairly typical for $zsim2$ SMGs. ASXDF1100.053.1 has $R_{rm e, mm}=1.0^{+0.2}_{-0.1}$ kpc, so its surface $L_{rm IR}$ density $Sigma_{rm IR}$ is $1.2^{+0.1}_{-0.2}times10^{12}$ L$_{odot}$ kpc$^{-2}$. These properties indicate that ASXDF1100.053.1 is a massive dusty star-forming (SF) galaxy with an unusually compact starburst. It lies close to the SF main sequence at $zsim5$, with low $M_{rm gas}$/$M_{rm stellar}=0.09$, SFR/SFR$_{rm MS} (R_{rm SB})=0.6$, and a gas-depletion time $tau_{rm dep}$ of $approx 50$ Myr, modulo assumptions about the stellar initial mass function in such objects. ASXDF1100.053.1 has extreme values of $M_{rm gas}/M_{rm stellar}$, $R_{rm SB}$, and $tau_{rm dep}$ compared to SMGs at $zsim$2-4, and those of ASXDF1100.053.1 are the smallest among SMGs at $z>5$. ASXDF1100.053.1 is likely a late-stage dusty starburst prior to passivisation. The number of $z=$5.1-5.3 unlensed SMGs now suggests a number density $dN/dz=30.4pm19.0$ deg$^{-2}$, barely consistent with the latest cosmological simulations." @default.
