A minimum-hypothesis explanation for the Radcliffe Wave:
  Kelvin-Helmholtz instability
  It is suggested that the wavelike character of the recently discovered
2.7-kiloparsec spatially and kinematically coherent complex of interstellar
clouds in the solar neighborhood--the Radcliffe Wave--may be the result of a
Kelvin-Helmholtz instability arising at the interface between the Galactic disk
and non-corotating halo.
