Separating Line Emission from Star Formation, Shocks, and AGN Ionisation in NGC 1068
Joshua J. D'Agostino, Lisa J. Kewley, Brent A. Groves +6
In the optical spectra of galaxies, the separation of line emission from gas ionised by star formation and an AGN, or by star formation and shocks, are very well-understood problem…
Comparison of Theoretical Starburst Photoionisation Models for Optical Diagnostics
Joshua J. D'Agostino, Lisa J. Kewley, Brent Groves +5
We study and compare different examples of stellar evolutionary synthesis input parameters used to produce photoionisation model grids using the MAPPINGS V modelling code. The aim…
The Effects of Diffuse Ionized Gas and Spatial Resolution on Metallicity Gradients: TYPHOON Two-Dimensional Spectrophotometry of M83
Henry Poetrodjojo, Joshua J. D'Agostino, Brent Groves +5
We present a systematic study of the diffuse ionized gas (DIG) in M83 and its effects on the measurement of metallicity gradients at varying resolution scales. Using spectrophotome…
A New Diagnostic to Separate Line Emission from Star Formation, Shocks, and AGN Simultaneously in IFU Data
Joshua J. D'Agostino, Lisa J. Kewley, Brent A. Groves +3
In the optical spectra of galaxies, methods for the separation of line emission arising from star formation and an additional hard component, such as shocks or AGN, is well-underst…
