Abstract

We present simultaneous observations of the superluminal radio galaxy 3C120 performed with the ASCA and GRO (OSSE) satellites on February-March 1994, as well as an analysis of all the ROSAT archival data. The ASCA spectrum of this object can be described by an absorbed (N_H=1.6e^21 cm^-2) power law with photon index Gamma_ASCA=2 and a very broad sigma>0.8 keV intense iron line (EW>400 eV) at ~ 6 keV. The combined ASCA--OSSE data do not exclude the presence of a narrower (sigma=0.4 keV) and less intense (EW<300 eV) iron line plus a hard component, corresponding either to reflection from an accretion disk or to a flatter power law from a jet. However a single power law plus broad Fe line is preferred from a statistical point of view by the AS...
