The luminosity (\(L\)) of a spiral galaxy is proportional to its rotational velocity (v) to the fourth power: \[ L\propto v^4 \nonumber \] The relationship is called the Tully-Fisher relation. By using spectral …
WebFisher equation. Then 1 B' = (1 + r)(l + p) where p is the expected inflation rate. This is equivalent to ^(TT^F-1 (3) which is in essence the Fisher relation, i = r + p + rp (4) where the cross-product term rp is usually ignored,1 and where ¿is the nominal rate with B' equal to (1 + i)"1. For B and B' to be equal, it would have to be the case
