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…
A Comparison of Rest-frame Ultraviolet and Optical Emission-Line Diagnostics in the Lensed Galaxy SDSS J1723+3411 at Redshift z=1.3293
J. R. Rigby, Michael Florian, A. Acharyya +13
For the extremely bright lensed galaxy SDSS J1723+3411 at z=1.3293 , we analyze spatially integrated MMT, Keck, and Hubble Space Telescope spectra that fully cover the rest-frame w…
Unravelling the enigmatic ISM conditions in Minkowski's Object
Henry R. M. Zovaro, Robert Sharp, Nicole P. H. Nesvadba +7
Local examples of jet-induced star formation lend valuable insight into its significance in galaxy evolution and can provide important observational constraints for theoretical mod…
Gas-phase metallicity gradients of TNG50 star-forming galaxies
Z. S. Hemler, Paul Torrey, Jia Qi +8
We present the radial gas-phase, mass-weighted metallicity profiles and gradients of the TNG50 star-forming galaxy population measured at redshifts 0--3. We investigate the re…
Oxygen Loss from Simulated Galaxies and the Metal Flow Main Sequence: Predicting the Dependence on Mass and Environment
Philip Taylor, Chiaki Kobayashi, Lisa J. Kewley
We predict the mass fraction of oxygen lost from galaxies in a cosmological simulation as a function of stellar mass and environment at the present day. The distribution with stell…
Spatial Variation in Strong Line Ratios and Physical Conditions in Two Strongly-Lensed Galaxies at z~1.4
Michael K. Florian, Jane R. Rigby, Ayan Acharyya +14
For studies of galaxy formation and evolution, one of the major benefits of the James Webb Space Telescope is that space-based IFUs like those on its NIRSpec and MIRI instruments w…
