Structural Analogs of the Milky Way Galaxy: Stellar Populations in the
  Boxy Bulges of NGC 4565 and NGC 5746
  We present NGC 4565 and NGC 5746 as structural analogs of our Milky Way. All
three are giant, SBb - SBbc galaxies with two pseudobulges, i. e., a compact,
disky, star-forming pseudobulge embedded in a vertically thick, "red and dead",
boxy pseudobulge that really is a bar seen almost end-on. The stars in the boxy
bulge of our Milky Way are old and enhanced in alpha elements, indicating that
star formation finished within ~ 1 Gyr of when it started. Here, we present
Hobby-Eberly Telescope spectroscopy of the boxy pseudobulges of NGC 4565 and
NGC 5746 and show that they also are made of old and alpha-element-enhanced
stars. Evidently it is not rare that the formation of stars that now live in
bars finished quickly and early, even in galaxies of intermediate Hubble types
whose disks still form stars now. Comparison of structural component parameters
leads us to suggest that NGC 4565 and NGC 5746 are suitable analogs of the
Milky Way, because they show signatures of similar evolution processes.
