We present new XMM-Newton observations of the supernova remnant N120 in theLMC, and numerical simulations on the evolution of this supernova remnant whichwe compare with the X-ray observations. The supernova remnant N120, togetherwith several HII regions, forms a large nebular complex5D (also called N120)whose shape resembles a semicircular ring. From the XMM-Newton data we generateimages and spectra of this remnant in the energy band between 0.2 to 2.0 keV.The images show that the X-ray emission is brighter towards the east (i.e.,towards the rim of the large nebular complex). The EPIC/MOS1 and MOS2 datareveal a thermal spectrum in soft X-rays. 2D axisymmetric numerical simulationswith the Yguaz\'u-a code were carried out assuming that the remnant isexpanding into an inhomogeneous ISM with an exponential density gradient andshowing that thermal conduction effects are negligible. Simulated X-rayemission maps were obtained from the numerical simulations in order to comparethem with the observations. We find good agreement between the XMM-Newton data,previous optical kinematic data, and the numerical simulations; the simulationsreproduce the observed X-ray luminosity and surface brightness distribution. Wehave also detected more extended diffuse X-ray emission probably due to theN120 large HII complex or superbubble.
