They are located on the upper branch of the Hubble tuning fork diagram, and four examples of them are found in the Coma Berenices, while three can be found in the Virgo cluster.
One explanation for the structure of this type of astronomical object is the Lin-Shu Hypothesis in which quasi-stationary density waves are posited to differentiate it from a similar type. They are located on the upper branch of the Hubble tuning fork diagram, and four examples of them are found in the Coma Berenices, while three can be found in the Virgo cluster. Thought to contain a super massive black hole at their center, their interiors are populated by older Population I stars, while expanses are populated by population II stars such as our sun. FTP, name these types of galaxies, one example of which is the Milky Way.
