2b. E + S Interaction
In this sub-category an E-like galaxy is interacting with another
galaxy which is classifiable as a disk or spiral galaxy. The
sub-category contains some very disrupted pairs shown in the middle of
the section, and spirals with long, open arms at the end. In AM
0228-342 there is a diffuse faint filament on the side of the
north-east galaxy which accounts for its interacting
classification. This object is placed in
Category 8 as well because of
its many apparent companions. The galaxies in AM 2254-364 are
classified as interacting because of the peculiar absorption on the
edge of the south-west member which is presumably due to the influence
of the large E galaxy. Because of this peculiar absorption this object
is also used as an illustration in
Category 14. Object AM 2225-250 is
the same as No. 93 in the
Atlas of Peculiar Galaxies
(Arp 1966).
