Spatially resolved direct method metallicity in a high-redshift analogue local galaxy: temperature structure impact on metallicity gradients
Alex J. Cameron, Tiantian Yuan, Michele Trenti +2
We investigate how HII region temperature structure assumptions affect "direct-method" spatially-resolved metallicity observations using multispecies auroral lines in a galaxy from…
Understanding Galaxy Evolution through Emission Lines
Lisa J. Kewley, David C. Nicholls, Ralph S. Sutherland
We review the use of emission-lines for understanding galaxy evolution, focusing on excitation source, metallicity, ionization parameter, ISM pressure and electron density. We show…
Theoretical ISM pressure and electron density diagnostics for local and high-redshift galaxies
Lisa J. Kewley, David C. Nicholls, Ralph S. Sutherland +4
We derive new self-consistent theoretical UV, optical, and IR diagnostics for the ISM pressure and electron density in the ionized nebulae of star-forming galaxies. Our UV diagnost…
Rest-frame UV and optical emission line diagnostics of ionised gas properties: a test case in a star-forming knot of a lensed galaxy at z~1.7
Ayan Acharyya, Lisa J. Kewley, Jane R. Rigby +7
We examine the diagnostic power of rest-frame ultraviolet (UV) nebular emission lines, and compare them to more commonly used rest-frame optical emission lines, using the test case…
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…
Calibrating Interstellar Abundances using SNR Radiative Shocks
Michael A. Dopita, Ivo R. Seitenzahl, Ralph S. Sutherland +4
Using integral field data we extract the optical spectra of shocked interstellar clouds in Kepler's supernova remnant located in the inner regions of our Galaxy, as well as in the…
