SYNCHROTRON-RADIATION FROM QUASI-MONOENERGETIC ELECTRONS - MODELING THE SPECTRUM OF SAGITTARIUS-A

We investigate the spectrum of a quasi-monoenergetic ensemble of relat ivistic electrons, especially for the mildly relativistic case, and di scuss the effect of inclination of the magnetic field on the emissivit y. We apply the exact theoretical description to the spectrum of the r adio source Sgr A which is located at or very close to the dynamical center of our Galaxy. We find that the radio-MIR spectrum can be repro duced well, but that the resulting self-comptonized X-ray flux is much smaller than the observed one.
