UNCOVER NIRSpec/PRISM Spectroscopy Unveils Evidence of Early Core Formation in a Massive, Centrally Dusty Quiescent Galaxy at $z_{spec}=3.97
We report the spectroscopic confirmation of a massive ($\log(M_\star/M_\odot)=10.34 \pm_{0.07}^{0.06}$), HST-dark ($m_\mathrm{F150W} - m_\mathrm{F444W} = 3.6$) quiescent galaxy at $z_{spec}=3.97$ in the UNCOVER survey. NIRSpec/PRISM spectroscopy and a non-detection in deep ALMA imaging surprisingly...

($\log(M_\star/M_\odot)=10.34 \pm_{0.07}^{0.06}$), HST-dark ($m_\mathrm{F150W}
- m_\mathrm{F444W} = 3.6$) quiescent galaxy at $z_{spec}=3.97$ in the UNCOVER
survey. NIRSpec/PRISM spectroscopy and a non-detection in deep ALMA imaging
surprisingly reveals that the galaxy is consistent with a low ($<$10 $M_\odot \
\mathrm{yr^{-1}}$) star formation rate despite evidence for moderate dust
attenuation. The F444W image is well modeled with a two component \sersic fit
that favors a compact, $r_e\sim200$ pc, $n\sim2.9$ component and a more
extended, $r_e\sim1.6$ kpc, $n\sim1.7$ component. The galaxy exhibits strong
color gradients: the inner regions are significantly redder than the outskirts.
Spectral energy distribution models that reproduce both the red colors and low
star formation rate in the center of UNCOVER 18407 require both significant
($A_v\sim1.4$ mag) dust attenuation and a stellar mass-weighted age of 900 Myr,
implying 50\% of the stars in the core already formed by $z=7.5$. Using
spatially resolved annular mass-to-light measurements enabled by the galaxy's
moderate magnification ($\mu=2.12\pm_{0.01}^{0.05}$) to reconstruct a radial
mass profile from the best-fitting two-component \sersic model, we infer a
total mass-weighted $r_\mathrm{eff} = 0.72 \pm_{0.11}^{0.15}$ kpc and
log$(\Sigma_\mathrm{1 kpc} \ [\mathrm{M_\odot/kpc^2}]) = 9.61
\pm_{0.10}^{0.08}$. The early formation of a dense, low star formation rate,
and dusty core embedded in a less attenuated stellar envelope suggests an
evolutionary link between the earliest-forming massive galaxies and their
elliptical descendants. Furthermore, the disparity between the global,
integrated dust properties and the spatially resolved gradients highlights the
importance of accounting for radially varying stellar populations when
characterizing the early growth of galaxy structure.</description><identifier>DOI: 10.48550/arxiv.2402.05664</identifier><language>eng</language><subject>Physics - Astrophysics of Galaxies</subject><creationdate>2024-02</creationdate><rights>http://creativecommons.org/licenses/by/4.0</rights><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>228,230,780,885</link.rule.ids><linktorsrc>$$Uhttps://arxiv.org/abs/2402.05664$$EView_record_in_Cornell_University$$FView_record_in_$$GCornell_University$$Hfree_for_read</linktorsrc><backlink>$$Uhttps://doi.org/10.48550/arXiv.2402.05664$$DView paper in arXiv$$Hfree_for_read</backlink></links><search><creatorcontrib>Setton, David J</creatorcontrib><creatorcontrib>Khullar, Gourav</creatorcontrib><creatorcontrib>Miller, Tim B</creatorcontrib><creatorcontrib>Bezanson, Rachel</creatorcontrib><creatorcontrib>Greene, Jenny E</creatorcontrib><creatorcontrib>Suess, Katherine A</creatorcontrib><creatorcontrib>Whitaker, Katherine E</creatorcontrib><creatorcontrib>Antwi-Danso, Jacqueline</creatorcontrib><creatorcontrib>Atek, Hakim</creatorcontrib><creatorcontrib>Brammer, Gabriel</creatorcontrib><creatorcontrib>Cutler, Sam E</creatorcontrib><creatorcontrib>Dayal, Pratika</creatorcontrib><creatorcontrib>Feldmann, Robert</creatorcontrib><creatorcontrib>Furtak, Lukas J</creatorcontrib><creatorcontrib>Fujimoto, Seiji</creatorcontrib><creatorcontrib>Glazebrook, Karl</creatorcontrib><creatorcontrib>Goulding, Andy D</creatorcontrib><creatorcontrib>Kokorev, Vasily</creatorcontrib><creatorcontrib>Labbe, Ivo</creatorcontrib><creatorcontrib>Leja, Joel</creatorcontrib><creatorcontrib>Ma, Yilun</creatorcontrib><creatorcontrib>Marchesini, Danilo</creatorcontrib><creatorcontrib>Nanayakkara, Themiya</creatorcontrib><creatorcontrib>Pan, Richard</creatorcontrib><creatorcontrib>Price, Sedona H</creatorcontrib><creatorcontrib>Siegel, Jared C</creatorcontrib><creatorcontrib>Shipley, Heath</creatorcontrib><creatorcontrib>Weaver, John R</creatorcontrib><creatorcontrib>van Dokkum, Pieter</creatorcontrib><creatorcontrib>Wang, Bingjie</creatorcontrib><creatorcontrib>Williams, Christina C</creatorcontrib><title>UNCOVER NIRSpec/PRISM Spectroscopy Unveils Evidence of Early Core Formation in a Massive, Centrally Dusty Quiescent Galaxy at $z_{spec}=3.97</title><description>We report the spectroscopic confirmation of a massive
