Bottom’s Dream and the Amplification of Filamentary Gas Structures and Stellar Spiral Arms

Theories of spiral structure traditionally separate into tight-winding Lin–Shu spiral density waves and the swing-amplified material patterns of Goldreich & Lynden-Bell and Julian & Toomre. In this paper we consolidate these two types of spirals into a unified description, treating density w...
