The Collisional and Photoionized Plasma in the Polarized NLS1 galaxy Mrk 1239

Mrk 1239 is a highly polarized NLS1 in the optical band, whose 0.3-3 keV spectrum has remained remarkably consistent over more than two decades of observation. Previous analysis of this object suggested that the soft X-ray band was dominated by emission lines (collisionally and/or photoionized) from the distant host galaxy... Show more
