Abstract Understanding the rapid formation of supermassive black holes in the early Universe requires insights into stellar mass growth in host galaxies. Here we present NIRSpec rest-frame optical spectra and NIRCam imaging from JWST of two galaxies at z > 6, both hosting moderate-luminosity quasars. These galaxies exhibit Balmer absorption lines, like low-redshift post-starburst galaxies.

Abstract With stunning clarity, the JWST has revealed the Universe’s first billion years. The scientific community is analysing a wealth of JWST imaging and spectroscopic data from that era, and is in the process of rewriting the astronomy textbooks. Here, as a result of the 2024 ISSI Breakthrough Workshop, we provide a snapshot of the great progress made towards understanding the initial chapters of our cosmic history 1.5 years into the JWST science mission.

A SPectroscopic Survey of Biased Halos in the Reionization Era (ASPIRE): JWST Reveals a Filamentary Structure around a z = 6.61 Quasar

Quasars, powered by accreting supermassive black holes (SMBHs) with masses of 108–1010 M⊙, have been observed up to z = 7.6 (Bañados et al. 2018; Yang et al. 2020a; Wang et al. 2021), deep into the epoch of reionization (EoR). How these quasars formed within the first billion years after the Big Bang is one of the most important open questions in astrophysics. Cosmological simulations suggest that billion-solar-mass SMBHs in the EoR formed in massive dark matter halos (e.g., Di Matteo et al.

Detection of stellar light from quasar host galaxies at redshifts above 6 - Nature

Abstract The detection of starlight from the host galaxies of quasars during the reionization epoch (z > 6) has been elusive, even with deep HST observations1,2. The current highest redshift quasar host detected3, at z = 4.5, required the magnifying effect of a foreground lensing galaxy. Low-luminosity quasars4,5,6 from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP)7 mitigate the challenge of detecting their underlying, previously-undetected host galaxies.
