Abstract

We present the Chandra-LETGS analysis of Mrk 279, a bright Seyfert 1 galaxy. The spectrum shows a variety of features arising from different physical environments in the vicinity of the black hole. We detect three absorption components, located at the redshift of the source. One of them is likely to arise from the host galaxy. An additional component due to absorption by a collisionally ionized gas at z=0 is also observed. Such an absorption can be produced in the outskirts of our Galaxy or in the local group. The emission spectrum is rich in narrow and broad emission features. We tested the hypothesis that the broad emission lines originate in the Broad Line Region (BLR), as studied in the UV band. We find that at least 2 components with different ionization parameters are necessary to simultaneously interpret the broad emission line measured in the UV (by HST-STIS and FUSE) and in the X-rays.
