Radial gradient in T_e for each of the PHANGS-MUSE galaxies. Red points show T_e determined from auroral line measurements, while black points show T_e measured using the charge-exchange method. Positive slopes show general agreement with the expected flat to negative metallicity gradients reported in these and other nearby galaxies (Pilyugin et al. 2014; Kreckel et al. 2019). A linear fit is shown for each galaxy, with the fit parameters listed in the top of each plot. The gray band indicates the uncertainty in the linear fit, accounting for 600 Κ systematic uncertainty in the T_e measurements.
