- For example, there is a very tight relation, called the Tully-Fisher relation, between the rotational velocity of a spiral galaxy and its luminosity.
- All of their stars are thought to be older than about a billion years, in agreement with their offset from the Tully-Fisher relation (see below).
- The clearest support for this theory, however, is their adherence to slightly shifted version of Tully-Fisher relation, discussed above.
- Mergers are also unable to account for the offset from the Tully-Fisher relation without assuming the merged galaxies were quite different from those we see today.
