The AURORA Survey: An Extraordinarily Mature, Star-forming Galaxy at $z\sim 7$

Understand

We present the properties of a massive, large, dusty, metal-rich, star-forming galaxy at z_spec=6.73.

• GOODSN-100182 was observed with JWST/NIRSpec as part of the AURORA survey, and is also covered by public multi-wavelength HST and JWST imaging.
• While the large stellar mass of GOODSN-100182 (~10^10 M_sun) was indicated prior to JWST, NIRCam rest-optical imaging now reveals the presence of an extended disk (r_eff~1.5 kpc).
• In addition, the NIRSpec R~1000 spectrum of GOODSN-100182 includes the detection of a large suite of rest-optical nebular emission lines ranging in wavelength from [OII]3727 up to [NII]6583.
