We present integrated-light spectra of 8 Young Massive Clusters ( YMCs ) in the metal-rich spiral galaxy NGC 5236 ( M 83 ) .
The observations were taken with the X-Shooter spectrograph on the ESO Very Large Telescope .
Through the use of theoretical isochrones and synthetic integrated-light ( IL ) spectra we derive metallicities and study the radial metallicity gradient observed through these young populations .
For the inner regions of the galaxy we observe a relatively shallow metallicity gradient of - 0.37 \pm 0.29 dex R _ { 25 } ^ { -1 } , agreeing with chemical evolution models with an absence of infall material and a relatively low mass loss due to winds in the inner parts of the disk .
We estimate a central metallicity of [ Z ] = + 0.17 \pm 0.12 dex , finding excellent agreement with that obtained via other methods ( e.g .
blue supergiants and J-band ) .
We infer a metallicity of 12+log ( O/H ) = 8.75 \pm 0.08 dex at R/R _ { 25 } = 0.4 , which fits the stellar mass-metallicity relation ( MZR ) compilation of blue supergiants and IL studies .
