Resumen:
In this work we combine SEDs, radio maps and polarizationobservations to understand the emission mechanisms in Cygnus X-1. Ourradiative model indicates that the MeV emission originates in the jet andthat all the very high-energy emission is from hadronic origin. We alsoperformed a synthetic radio map that suggests that our description of themagnetic eld should be improved, since it leads to a very compact emissionregion. In order to choose the most suitable magnetic eld geometry,we investigated the polarization in X-rays and we found that very simplegeometries can explain the high levels of polarization reported by otherauthors.
