Scientific paper

New observations of the filaments around NGC 1275 are presented. Absolute intensities of the emission lines in the two velocity systems at 5300 and 8200 km/s are given. The possible sources of ionization and excitation are investigated in detail. The spectra of the high-velocity filaments strongly resemble those of giant H II regions in the outer parts of spiral galaxies. The low-velocity spectra can be equally well explained by collisional ionization in strong shocks or in terms of photoionization by the Seyfert nucleus. Current observations support the hypotheses that (1) the high-velocity system is an infalling spiral galaxy bound to the Perseus cluster, and (2) the low-velocity filaments are condensations in an accretion flow onto NGC 1275
