AM 1029-343

Only spirals that have peculiarities in the main body of the galaxy have been placed in Category 12. There are a large number of different kinds of peculiarities shown in the few illustrations given in this photographic section. The comments in Volume I will identify the particular peculiarity placing a galaxy in this Category. On page 12.1 the spiral shows a nuclear region that is rectangular in cross section. The next galaxy AM 1234-415, shows a condensation, presumably of stars, projected onto, or actually in, the bar of a barred spiral. Following this, the barred spiral AM 0421-404 at first sight seems normal; closer inspection however shows that the bar is not straight or symmetrical but slightly curved. The outer distorted ring in AM 1029-343 is of quite high surface brightness. In AM 2001-602 there is a faint outer ring around the bright inner arcs of the galaxy. The succeeding pages show various highly disturbed objects which are just recognizable as possible spiral galaxies.

On page 12.4 we see AM 1843-651 which has a very-high-surface brightness disk and a very low-surface-brightness halo; the following page gives four more examples of this phenomenon. Some miscellaneous objects are found on page 12.6, including AM 0119-341, which has relatively bright, compact condensations in its disk. In AM 1505-253, aside from the straight arrangement of stellar and non-stellar appearing objects, the nucleus inside the ring of spiral structure is relatively small. On the final page illustrating this Category are two dwarf systems; both AM 0311-252 and AM 0510-330 show spiral patterns but no sign of a nucleus.
