The dearth of high quality spectroscopy of dusty star-forming galaxies (DSFGs) -- the main drivers of the assembly of dust and stellar mass at the peak of activity in the Universe -- greatly hinders our ability to interpret their physical processes and evolutionary pathways. We present JWST/NIRSpec observations from RUBIES of four submillimeter-selected, ALMA-detected DSFGs at cosmic noon, $z\sim2.3-2.7$. While photometry uniformly suggests vigorous ongoing star formation for the entire sample in line with canonical DSFGs, the spectra differ: one source has spectroscopic evidence of an evolved stellar population, indicating a recent transition to a post-starburst phase, while the remainder show strong spectroscopic signatures of ongoing starbursts. All four galaxies are infrared-luminous (log$_{10}$$L_{\rm{IR}}$/L$_{\rm \odot}$ $>12.4$), massive (log$_{10}\,M_\star$/M$_{\rm \odot}$ $>11$), and very dust-obscured ($A_V\sim3-4$ ABmag). Leveraging detections of multiple Balmer and Paschen lines, we derive an optical attenuation curve consistent with Calzetti overall, yet an optical extinction ratio $R_V\sim2.5$, potentially indicating smaller dust grains or differences in star-dust geometry. This case study provides some of the first detailed spectroscopic evidence that the DSFGs encompass a heterogeneous sample spanning a range of star formation properties and evolutionary stages, and illustrates the advantages of synergistic JWST and ALMA analysis of DSFGs.

Exploring the mid-infrared SEDs of six AGN dusty torus models I: synthetic spectra
在远离活动星系核(AGN)的地方,环境温度低于1500-1800 K,尘埃能够存活。因此,有可能存在一个围绕活动星系核的大尘埃结构。这是两篇论文中的第一篇,旨在比较六个尘埃环面模型与可用的SED,即Fritz et al.(2006),Nenkova et al.(2008 B),Hoenig & Kishimoto(2010),Siebenmorgen et al.(2015),Stalevski et al.(2016)和Hoenig & Kishimoto(2017)。在这第一篇论文中,我们使用合成光谱来探索这些模型之间的区别,在何种情况下,他们允许限制环面参数,而我们的第二篇论文分析了最好的模型来描述中红外光谱数据。我们已经产生了合成光谱,从目前的仪器:GTC/CanariCam和斯皮策/IRS和未来的JWST/MIRI和JWST/NIRSpec仪器。我们发现,对于一个合理的亮度(F12 um> 100 mJy),我们实际上可以区分模型之间,除了两对父模型。我们表明,这些模型可以区分的基础上的连续斜率和强度的硅酸盐功能。此外,对于除Hoenig & Kishimoto(2017)之外的所有模型,无论使用何种仪器,其参数都可以限制在15%的误差范围内。然而,当超过50%的环核贡献者被包括在内时,参数估计被破坏。因此,未来的高空间分辨率光谱,如那些预期从JWST将提供足够的覆盖…
