WebThe Keck rotation velocities define a Tully-Fisher relation (i.e., the correlation of rotation velocity with blue magnitude) which matches to within 0.5 mag that for nearby spirals. Spiral galaxy evolution, over the last half of the age of the universe, has not significantly altered the Tully-Fisher correlation. WebOct 11, 2024 · Spirals in galaxies have long been thought to be caused by gravitational instability in the stellar component of the disk, but discerning the precise mechanism had proved elusive. Tidal interactions, and perhaps bars, may provoke some spiral responses, but spirals in many galaxies must be self-excited.
