Galactic structure Bar serves cosmic scorpion

Abstract: Many galaxies have intensely bright nuclei, perhaps containing massive black holes. To be so luminous, these nuclei must have a supply of gas to use as fuel, either for accretion or nuclear burning. In certain types of spiral galaxy the gas may get driven into the centre by tides from large bar-shaped structures. This idea is bolstered by a striking new image of a scorpion-like galaxy, where star-forming regions extend in a spiral right into the galactic core.
