Result of the iterative AGN-host deblending for Mrk 1044 in spectral (left) and spatial (right) dimensions. The panel on the left shows the original blended spectrum (black) within a 3″ aperture centered on the QSO position. The AGN emission (red) contains the broad lines, whereas in the host galaxy spectrum (blue) only narrow emission lines are present. The bright point-like AGN emission distributes over the entire FOV of the data cube which is captured by the Hα narrow-band images on the right. Both original (left) and deblended host (right) images share the same color-scaling, which demonstrates the successful deblending.
