galactic latitude

[gə′lak·tik ′lad·ə‚tüd]
(astronomy)
Angular distance north or south of the galactic equator; the arc of a great circle through the galactic poles, between the galactic equator and a point on the celestial sphere, measured northward or southward from the galactic equator through 90° and labeled N or S to indicate the direction of measurement.

The map looks above (top) and below (bottom) the plane of the Milky Way, centered on the galactic pole, with larger circles representing lower galactic latitudes. The black box (bottom) shows where BICEP2 looked for gravitational waves.
The first detections of dust-correlated AME originate from CMB experiments measuring the sky at high Galactic latitudes, and thus authors have often calculated the dust "emissivity" in terms of the radio brightness relative to a dust template map.
Specific papers address such issues as the radiative equilibrium of a planetary nebula, faint white stars at low galactic latitudes, the diffusion of photons through a scattering medium in connection with application to some astrophysical problems, a point light sources in a turbid medium, the problem of fluctuations of the brightness of the Milky Way, and the distribution of ozone in the Earth's atmosphere.
This galactic cirrus--twisted clouds of interstellar dust particles at high galactic latitudes first observed in the far infrared in 1983-84 by the Infrared Astronomy Satellite (IRAS)--glows in the dim red region of the spectrum.
The maps showed the re-emitted thermal radiation of dust grains heated by starlight from the galactic disk; they also helped researchers measure the amount of light extinction or interstellar reddening at high galactic latitudes. Interstellar dust absorbs and scatters blue light preferentially, allowing red light to pass with less interference.
Blanco, who noticed that the area contains five times the usual concentration (at similar galactic latitudes) of stars brighter than 9th magnitude of spectral type A0.
(Some of these are distant super-giants, but most are closer and less luminous.) Of the 23 brightest stars, 18 are at galactic latitudes of 25 [degrees] or less.
