  • A new idea is proposed for the origin of bulges in spiral galaxies. Numerical simulations of protogalactic collapse suggest strongly that galactic bulges have been assembled from massive clumps formed in galactic disks in their early evolutionary phase. These clumps result from the gravitational instability of the gas-rich disks of young galaxies. Owing to dynamical frictions, those massive clumps, individual masses of which can be as large as ~109 M?, are able to spiral toward the galactic… CONTINUE READING
