We present the first results of BeppoSAX observations of a small sample of low brightness FRI radio galaxies. The flux of all the targets is consistent with a thermal spectrum, as due to the presence of hot intracluster gas or galactic corona. Moreover in three sources a non thermal absorbed spectrum can be present in the MECS spectrum at energies greater than or similar to 7 keV, while for a fourth object a high energy flux has been detected in the PDS instrument at energies greater than or similar to 15 keV. This component could be related to the inner AGN surrounded by an obscuring torus.

Abstract
We present the first results of BeppoSAX observations of a small sample of low brightness FRI radio galaxies. The flux of all the targets is consistent with a thermal spectrum, as due to the presence of hot intracluster gas or galactic corona. Moreover in three sources a non thermal absorbed spectrum can be present in the MECS spectrum at energies greater than or similar to 7 keV, while for a fourth object a high energy flux has been detected in the PDS instrument at energies greater than or similar to 15 keV. This component could be related to the inner AGN surrounded by an obscuring torus.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
