An Estimate of the Impact of Reionization on Supermassive Black Hole Growth
Phoebe R. Upton Sanderbeck, Jarrett L. Johnson, Madeline A. Marshall
The supermassive black holes (SMBHs) that power active galactic nuclei found at were formed during the epoch of reionization. Because reionization is an inhomogeneous proce…
GA-NIFS: JWST discovers an offset AGN 740 million years after the Big Bang
Hannah Übler, Roberto Maiolino, Pablo G. Pérez-González +24
A surprising finding of recent studies is the large number of Active Galactic Nuclei (AGN) associated with moderately massive black holes (), i…
Metal enrichment and evolution in four z > 6.5 quasar sightlines observed with JWST/NIRSpec
L. Christensen, P. Jakobsen, C. Willott +7
We present JWST/NIRSpec R~2700 spectra of four high-redshift quasars: VDES J0020-3653 (z = 6.860), DELS J0411-0907 (z = 6.825), UHS J0439+1634 (z = 6.519) and ULAS J1342+0928 (z =…
GA-NIFS: Black hole and host galaxy properties of two z6.8 quasars from the NIRSpec IFU
Madeline A. Marshall, Michele Perna, Chris J. Willott +20
Integral Field Spectroscopy (IFS) with JWST NIRSpec will significantly improve our understanding of the first quasars, by providing spatially resolved, infrared spectroscopic capab…
