Common Excitation Patterns of Star Formation, Active Galactic Nuclei, and Shocks in Seyfert Galaxies
Peixin Zhu, Lisa J. Kewley, Dominika Ł. Król +6
The growth of galaxies and their central supermassive black holes is closely connected, yet the net effect of active galactic nuclei (AGN) feedback on host-galaxy star formation re…
The Small-scale Structures in the Wind of Messier 82
Yucheng Guo, Timothy Heckman, Sanchayeeta Borthakur +10
Small-scale multiphase structure plays a central role in galactic-wind evolution, yet the parsec-scale morphology and excitation of the warm ionised gas remain poorly constrained.…
The Internal Nebular Attenuation Curve of Three-Dimensional Turbulent HII regions
Yifei Jin, Yong Shi, Ralph Sutherland +2
The internal dust attenuation of the Hii region reduces the observed emission-line fluxes. Turbulent density fields within each Hii region change the degree of the line-of-the-sigh…
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…
Strong nebular HeII emission induced by He ionizing photons escaping through the clumpy winds of massive stars
Arpita Roy, Mark R. Krumholz, Stefania Salvadori +8
The origin of nebular HeII-emission in both local and high-redshift galaxies remains an unsolved problem. Various theories have been proposed to explain it, including HeII-ionizati…
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…
A model for the emission line galaxy luminosity function and flux ratios at high-redshifts
Aadarsh Pathak, J. Stuart B. Wyithe, Ralph S. Sutherland +1
We present emision line flux ratio predictions for galaxies at using the MAPPINGS V v5.2.0 photoionization modelling code combined with an analytic…
The mass-metallicity and fundamental metallicity relations in non-AGN and AGN-host galaxies
Song-Lin Li, Kathryn Grasha, Mark R. Krumholz +5
Galaxies' stellar masses, gas-phase oxygen abundances (metallicity), and star formation rates (SFRs) obey a series of empirical correlations, most notably the mass-metallicity rela…
Spatially-Resolved Temperature and Density Structures of Nearby HII regions
Yifei Jin, Ralph Sutherland, Lisa Kewley +1
Photoionization models frequently assume constant temperature or density within HII regions. We investigate this assumption by measuring the detailed temperature and density struct…
