Supermassive black holes with high accretion rates in active galactic nuclei. VII. Reconstruction of velocity-delay maps by maximum entropy method

As one of the series of papers reporting on a large reverberation mapping campaign, we apply the maximum entropy method (MEM) to 9 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 6 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 an inflow and outflow, respectively. These super-Eddington accretors show diverse geometry and kinematics. Brief discussions of their BLRs are provided for each individual object.
