Using the integral field spectrograph Tiger, we obtained low to intermediate spectral resolution 3D data cubes of the cD galaxy NGC 1275. This set up allowed us to disentangle the various astrophysical components by individually mapping the galaxy continuum and the low and high velocity emission line systems with a yet unchallenged 0.8" spatial resolution.The low velocity system, which is elongated in an east-west direction similar to that of the molecular gas, exhibits trends in spectral characteristics which are consistent on the west side of the nucleus with photoionization by a varying mixture of nuclear radiation and local emission from hot young stars.The high velocity system is only seen north of the nucleus. We report the first detection of gas with velocities intermediate between the LV and HV systems, which we interpret as the first direct evidence of an interaction between the two velocity systems.
