Title: THE SOFT X-RAY EMISSION LINE SPECTRUM OF MARKARIAN 3
Observer: KAHN
Subject Category: Active Galaxies and Quasars
Seq: 700178 ObsId: 00873
Long-term Plan bin: 14-Mar-2000
ABSTRACT
X-ray spectra of Seyfert II galaxies exhibit discrete spectral features in the soft X-ray band. The line formation mechanisms are not well understood and detailed spectroscopy will provide a wealth of information about the structure of the circumnuclear regions. Mkn 3 is one of the brightest Seyfert II galaxies in soft X-rays and we propose an AXAF observation with the HETGS to obtain high resolution X-ray spectra of the emission-line regions in Mkn 3. Our primary goal is to determine the underlying line emission mechanisms and to constrain the ionization structure of the active nucleus.
