DESCRIPTION:While simulations can model galaxy formation and evolution at 
 high resolutions\, reproducing observations remains challenging. Significa
 nt work has been done towards creating synthetic data cubes from simulatio
 ns\, mimicking the data we obtain from integral field spectrographs. This 
 aligns with a key objective of the MAGPI survey\, an ESO MUSE Large Progra
 m designed to bridge the gap between observations and simulations at lookb
 ack times of 3 - 4 Gyrs (z = 0.3). Combining adaptive optics with MUSE has
  resulted in spatially resolved maps of stellar and ionised gas for hundre
 ds of galaxies beyond z = 0\, which has allowed us to capture radial trend
 s of star formation in galaxies from above to below the star-forming main 
 sequence (SFMS). This investigation reveals that starburst galaxies are sh
 own to evolve from uniformly to centrally enhanced star formation (SF) acr
 oss cosmic time with the most significant evolution at late times. Using m
 ock observations from EAGLE\, IllustrisTNG\, and Magneticum simulations\, 
 we now investigate the internal and external mechanisms shaping the radial
  trends of MAGPI galaxies. A good agreement between observations and simul
 ations is only found for galaxies far below the SFMS\, where we capture ev
 idence for inside-out quenching. The simulations broadly agree between 1 -
  4.5 Re but show varying central suppression within R ~ 1.5 Re for galaxie
 s on and below the SFMS\, attributable to different AGN feedback prescript
 ions. Central galaxies are subject to internal and external mechanisms\, s
 howing increased SF suppression in the centre with increasing halo mass\, 
 indicating AGN feedback. Satellites display increasing suppression in the 
 outskirts as halo mass increases\, indicative of environmental processes. 
 These results demonstrate the power of spatially resolved studies of galax
 ies\; while global properties align\, radial profiles reveal discrepancies
  between observations and simulations and their underlying physics.
