Insights for Early Massive Black Hole Growth from JWST Detection of the [Ne v] λ3427 Emission Line

We use the narrow [Ne v] λ 3427 emission line detected in the recently published JWST spectra of two galaxies, at z  ≃ 6.9 and 5.6, to study the key properties of the active galactic nuclei (AGN) and the supermassive black holes (SMBHs) in their centers. Using a new empirical scaling linking the $\l...
