The Role of the Synchrotron Component in the Mid-Infrared Spectrum of M 87

We study in detail the mid-infrared (MIR) Spitzer-IRS spectrum of M 87 in the range 5-20 Delta *mm. Thanks to the high sensitivity of our Spitzer-IRS spectra we can disentangle the stellar and nuclear components of this active galaxy. To this end, we have properly subtracted from the M 87 spectrum t...
