Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. VII. Reconstruction of Velocity-delay Maps by the Maximum Entropy Method

As one of a series of papers reporting on a large reverberation mapping campaign, we apply the maximum entropy method (MEM) to nine narrow- line Seyfert 1 galaxies with super-Eddington accretion rates observed during 2012-2013 for the velocity-delay maps of their H beta and H gamma emission lines. The maps of six objects are reliably reconstructed using MEM. The maps of H beta and H gamma emission lines of Mrk 335 indicate that the gas of its broad-line region (BLR) is infalling. For Mrk 142, its H beta and H gamma lines show signatures of outflow. The H beta and H gamma maps of Mrk 1044 demonstrate complex kinematics-a virialized motion accompanied by an outflow signature, and the H beta map of IRAS F12397+3333 is consistent with a disk or a spherical shell. The H beta maps of Mrk 486 and MCG +06-26-012 suggest the presence of inflow and outflow, respectively. These super-Eddington accretors show diverse geometry and kinematics. Brief discussions of their BLRs are provided for each individual object.
