ABSTRACT:The FIR, H I, radio continuum, and soft X-rays in the area of the North Celestial Pole (NCP) Loop are described.
Various expansion models are
considered and it is found that a cylindrical expansion best matches H I radial
velocities.
The expansion velocity is found to be about 20 km/s.
The NCP Loop is
believed to be a massive expanding mantle of a cylindrical cavity in the galactic
H I disk.
