The Nature of Nitrogen Enhanced High Redshift Galaxies
Peixin Zhu, James Trussler, Lisa J. Kewley
Recent JWST observations have revealed a population of high-redshift galaxies () exhibiting unexpectedly bright ultraviolet (UV) nitrogen emission lines. The strong N II…
Only Nitrogen-Enhanced Galaxies Have Detectable UV Nitrogen Emission Lines at High Redshift
Peixin Zhu, Lisa J. Kewley, Tiger Yu-Yang Hsiao +1
The detections of bright UV nitrogen emission lines in some high-redshift galaxies suggest unexpectedly high nitrogen-to-oxygen ratios () compared to loca…
CLASSY XII: Nitrogen Enrichment Shaped by Gas Density and Feedback
Karla Z. Arellano-Córdova, Danielle A. Berg, Matilde Mingozzi +25
We investigate the chemical evolution of N/O using a sample of 45 local star-forming galaxies (SFGs) from the CLASSY survey. This sample spans a wide range of galaxy properties, wi…
A Theoretical Three-Dimensional Diagram to Separate Star Formation, Active Galactic Nuclei, and Shocks in Galaxies
Peixin Zhu, Lisa J. Kewley, Ralph S. Sutherland +1
The excitation sources in galaxies are frequently mixed due to AGN and stellar feedback, including star formation, active galactic nuclei (AGNs), and shock excitation. Disentanglin…
The Cosmic Evolution Early Release Science Survey (CEERS)
Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +96
We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hour Director's Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates e…
Theoretical Diagnostics for Narrow Line Regions of Active Galactic Nuclei
Peixin Zhu, Lisa J. Kewley, Ralph Sutherland
Gas metallicity, ionization parameter, and gas pressure can affect the observed ratios of specific strong emission lines within galaxies. While the theoretical strong lines diagnos…
