The spiral galaxies that are associated with the cluster are typically found in the outskirts, and the lenticular galaxies
, such as NGC 4894, are generally intermediate both in morphology and distance from the cluster core.
And if we leave aside the so-called irregular galaxies, there are the lenticular galaxies
, among which are the very unusual but not-so-rare spindle galaxies.
This leads the astronomers to think that ultimately the galaxies will be dominated by the stellar bulge and become elliptical or lenticular galaxies

: the continuing formation of early-type galaxies," Monthly Notices of the Royal Astronomical Society, vol.
It is known that the Tully-Fisher relation holds for spiral and lenticular galaxies
with the same slope (e.g., ).
It classifies galaxies into two main groups: Ellipticals and spirals, with lenticular galaxies
as a transitional group.

"At this point, we don't know how common these clusters are or if they occur exclusively in lenticular galaxies
, " said Brodie.
might have evolved from spiral galaxies.
have a central bulge but no spiral arms, and are sometimes referred to as "armless spiral galaxies." These galaxies are often orbited by gravitationally bound collections of thousands of older stars, called globular clusters.
, according to NASA, are intermediate-state galaxies that exist somewhere in between the spectrum of elliptical and spiral galaxies, and are characterized by a bulge and a thin stellar disk.
SAURON was specifically designed to study the kinematics and stellar populations of a sample of nearby elliptical and lenticular galaxies
. The application of SAURON to spiral galaxies was restricted to the study of spiral bulges .
