Galactic disks evolve secularly through transient, self-quenching spiral episodes excited non-resonantly by mild gradients (cavernae), with high-multiplicity spirals dominating in cold disks and lower-multiplicity ones in warmer disks as heating efficiency changes.

Nexae in caverna: the secular evolution of disks via collectively excited, transient spiral structure
Galactic disks evolve secularly through transient, self-quenching spiral episodes excited non-resonantly by mild gradients (cavernae), with high-multiplicity spirals dominating in cold disks and lower-multiplicity ones in warmer disks as heating efficiency changes.
