The Physical Universe: An Introduction to Astronomy
The Galactic halo contains stars of large random velocities, and these stars are
less tightly bound to the Galaxy than the stars in the central bulge. It is not known
whether there is a smooth transition from the stars in the central bulge to the stars
...

The Formation of the Milky Way
This vertical structure may explain certain puzzling observations of the galactic
halo, such as conflicting c/a values for the shape of the halo, and unusual velocity
dispersions and/or distributions near the galactic poles. These results are in ...

Planetary Nebulae in Our Galaxy and Beyond (IAU S234)
But only 13 are known to be Galactic halo objects. Halo PNe are characterized by
their height above the Galactic plane, peculiar velocity compared to the Galactic
rotation curve of the disk components and also their low metallicity. These halo ...

halo may be derived by optical means are the extreme population II objects such
as RR Lyrae variables with periods longer than 004 days, the sub-dwarfs,

Galactic and Intergalactic Magnetic Fields
The observed X-ray emission implies halo gas densities of the order of 10~3/cm3
at 106 - 107 °K. The X-ray emission is sufficiently intense that the cooling times of
the galactic halo are small compared to the Hubble time, raising the question ...
