We report new radio observations of SDSS J090122.37+181432.3, a strongly lensed star-forming galaxy at $z=2.26$. We image 1.4 GHz (L-band) and 3 GHz (S-band) continuum using the VLA and 1.2 mm (band 6) continuum with ALMA, in addition to the CO(7-6) and CI(${\rm ^3P_2\rightarrow ^3\!P_1}$) lines, all at $\lesssim1.^{\prime\prime}7$ resolution. Based on the VLA integrated flux densities, we decompose the radio spectrum into its free-free (FF) and non-thermal components. The infrared-radio correlation (IRRC) parameter $q_{\rm TIR}=2.65_{-0.31}^{+0.24}$ is consistent with expectations for star forming galaxies. We obtain radio continuum-derived SFRs that are free of dust extinction, finding $\rm {620}_{-220}^{+280}\,M_\odot\,yr^{-1}$, $\rm {230}_{-160}^{+570}\,M_\odot\,yr^{-1}$, and $\rm {280}_{-120}^{+460}\,M_\odot\,yr^{-1}$ from the FF emission, non-thermal emission, and when accounting for both emission processes, respectively, in agreement with previous results. We estimate the gas mass from the CI(${\rm ^3P_2\rightarrow ^3\!P_1}$) line as $M_{\rm gas}=(1.2\pm0.2)\times10^{11}\,M_\odot$, which is consistent with prior CO(1-0)-derived gas masses. Using our new IR and radio continuum data to map the SFR, we assess the dependence of the Schmidt-Kennicutt relation on choices of SFR and gas tracer for $\sim{\rm kpc}$ scales. The different SFR tracers yield different slopes, with the IR being the steepest, potentially due to highly obscured star formation in J0901. The radio continuum maps have the lowest slopes and overall fidelity for mapping the SFR, despite producing consistent total SFRs. We also find that the Schmidt-Kennicutt relation slope is flattest when using CO(7-6) or CI(${\rm ^3P_2\rightarrow ^3\!P_1}$) to trace gas mass, suggesting that those transitions are not suitable for tracing the bulk molecular gas in galaxies like J0901.

Gas and Star Formation from HD and Dust Emission in a Strongly Lensed Galaxy
高红移星系的分子气体含量是一个非常受欢迎的特性。然而,H $_2$在大多数环境中无法直接观察到,因此其质量通过其他发射线探测(例如,CO、[Cl]、[CII])或通过气体与粉尘的比率。这些方法中的每一种都依赖于几个假设,并且最好并行使用。在这项工作中,我们扩展了一个额外的分子气体示踪高红移的研究,通过观察氘化氢(HD)发射的强透镜$z=5.656$星系SPT 0346 -52与ALMA。虽然没有检测到HD(1-0)发射,但我们能够对$\rm M_{H_2}<6.4\times10^{11} M_{\odot}$的气体质量设定上限。这用于找到$\rmα_{CO}<5.8$ M $_{\odot}$(K km s $^{-1}$ pc $^2$)$^{-1}$的$\rm L'_{CO}$转换因子的极限。此外,我们构建了最完整的光谱能量分布(SED)的这个来源的日期,并将其与一个单一的温度修改的黑体使用嵌套的采样代码MultiNest,产生一个最适合的尘埃质量$\rm M_{dust}=10^{8.92\pm0.02}$ M $_{\odot}$,尘埃温度$78.6\pm0.5$ K,尘埃发射率光谱指数$β=1.81\pm0.03$,和恒星形成率$\rm SFR=3800\pm100$ M $_{\odot}$年$^{-1}$。使用连续通量密度来估计源的总气体质量,我们发现$\rm M_…
