Abstract

In its first part, this paper summarizes recent work on the mass andshape of the Galactic dark halo. The second part presents a review ofthe large-scale structure of the Milky Way, and of the evidence thatthe inner Galaxy is dominated by baryonic matter. This is brieflycompared with the predictions of ΛCDM and MOND. Finally, asummary is given of bulge formation from clumpy, gas-rich disks, aprocess which may give rise to old, disk-like, α-rich bulgessimilar to the Galactic bulge.
