Jet-clump interactions in quasars

Some high redshift quasars (z∼4) show strong emission lines for C, N, and O, indicating high abundances of these elements. In this context, we have explored the nucleosynthesis that would occur between a high energy particle jet emanating from an Active Galactic Nucleus (AGN) and nearby gas. CNO pro...

Description
Summary:Some high redshift quasars (z∼4) show strong emission lines for C, N, and O, indicating high abundances of these elements. In this context, we have explored the nucleosynthesis that would occur between a high energy particle jet emanating from an Active Galactic Nucleus (AGN) and nearby gas. CNO production proceeds through nuclides which result from collisions between the jet and the gas. Final abundances of the CNO nuclides vary widely over the densities studied, but reach and even exceed solar levels for some combinations of temperature, density, and jet intensity and duration.
