The "Death Star" type of this entity was the first example of one striking its companion with a jet of energy.
The "Death Star" type of this entity was the first example of one striking its companion with a jet of energy. Energetic varieties of these include the Pea and LIRG types. The luminosity and rate of rotation of these are related by the Tully-Fisher relation. Dark matter is a solution to a problem stemming from their observed rotation curves. Emissions from the radio variety of these are due to synchrotron emission from their cores, which may be the result of their active nuclei. Objects in their halos include globular clusters, and some of these contain supermassive black holes in their centers. Name these entities, the spiral type of which is exemplified by the Milky Way.
