This page lists the total luminosity of the Milky Way Galaxy to be $4\times10^{10}$ $L_{sol}$, and $L_{sol}=3.86 \times10^{33}$ ergs.sec$^{-1}$; this gives a total luminosity for the MW of $1.54\times10^{44}$ ergs.sec$^{-1}$.
But Seyfert galaxies can have luminosities of $\sim 10^{40} - 10^{42}$ ergs.sec$^{-1}$, and this is due to the high luminosity of the galactic core of a Seyfert.
Since the MW doesn't have an active SMBH, does this mean that the MW is particularly bright due to a high luminosity stellar population? Or am I missing something?
