Re:NGC 5279
NGC 5278-5279. This Markarian system (Mrk 271) exhibits a spectrum with
very bright and broad emission lines in the nucleus. The spectral lines
of both components are inclined in opposite directions, indicating that
they rotate in opposite directions. The rotation curve of the primary
galaxy flattens out, albeit with certain velocity variations. The main
specific feature of this system are strongly noncoincident positions and
radial velocities of the dynamic and photometric centers of both
components (3" and 100 km s^-1^ for NGC 5278 and 6" and 20 km s^-1^ for
NGC 5279, respectively). A detailed photometric analysis of the system
performed by Mazzarella and Boroson (1993) revealed a number of regions
or spots of enhanced brightness and the brightest of them is located in
the satellite. The strong difference between the dynamic and
photometric centers mentioned above may be explained by a similar
inhomogeneity of the photometric properties of the two components. The
latter may be due, in turn, to the interaction between the galaxies.
Numerous determinations of the radial velocities of the component
centers yielded results that show a rather substantial scatter. The
LEDA database gives the velocities of 7558+/-79 and 7580+/-46 km s^-1^
for the primary galaxy and the satellite, respectively. No published
rotation curve could be found in the literature.
