BeppoSAX observation of NGC 3079

Using the BeppoSAX observatory, we have observed a nearby LINER/Seyfert 2 g alaxy, NGC 3079, which is known as an outflow galaxy and a bright H2O maser source. Using the Phoswich Detection System, we have revealed that the NGC 3079 nucleus suffers from a Compton-thick absorption, with a hydrogen colu mn density similar to 10(25) cm(-2). After corrected the absorption, the 2- 10 keV luminosity becomes 10(42)-10(43) ergs s(-1) at a distance of 16 Mpc. It is 2-3 orders of magnitude higher than that observed in the Medium Ener gy Concentrator Spectrometer band (below 10 keV). We also detected a strong Fe K line at 6.4(-0.2)(+0.3) keV with an equivalent width of 2.4(-1.5)(+2. 9) keV, which is consistent with the heavy absorption.
