Resumen: Powerful jets in high-mass microquasars are likely to be crossed by dense inhomogeneities (clumps) from the stellar winds, which may lead to particle acceleration and thus nonthermal emission in X-rays and gamma-rays. We characterise a typical clump-jet interaction scenario and compute the contribution to the high-energy emission of these systems. We use hydrodynamical simulations of a single clump-jet interaction and we use this result to compute its non-thermal (synchrotron and inverse Compton) radiation. We present several radiative calculations for a number of clump states, as the clump is disrupted over time, letting different parameters vary (viewing angle, magnetic field). We obtain significant amounts of non-thermal radiation from jet-clump interactions in high-mass microquasars
