WebApr 13, 2024 · At similar stellar masses and emission line ratios to the z = 9.51 galaxy, less than 1% of the local galaxies were classified as AGN. If this fraction does not substantially evolve with redshift, it is unlikely that the z = 9.51 galaxy hosts an AGN. WebArchitectural Sheet Metal.

WebSep 1, 1993 · Abundances do not depend significantly on the age of quasars. The nuclear metallicity may be rapidly generated and maintained at approximately time-stationary values. We review two mechanisms proposed for the metallicity enrichment of quasars and, in general, all active galactic nuclei (AGN). WebAccounting for complex density gradients and temperature profiles is critical for reliably estimating the fundamental properties of Hii regions and galaxies. Diffuse ionized gas can raise metallicity estimates, flatten metallicity gradients, and introduce scatter in ionization parameter measurements.
