GALEX Diffuse UV Background

9. Maps of the Sky, showing GALEX targets

 9.01
First, here are the GALEX Team Planned Observations (green), together with the TD-1 stars (black). Notice how GALEX stays away from the galactic plane! That is because of the dangers posed by bright stars.
 9.02
Next,the GALEX Team Planned Observations (black, now), together with (red) our Voyager targets. This map shows South Galactic Pole regions most clearly; but...
 9.03
... here we see the same information, but with the North Galactic Pole regions centered.
 9.04
Those maps are part of what we used to create our Cycle 1 and Cycle 2 proposals. Here is a summary of "who won what" in the two cycles of competition (with JHU and STScI programs in red).
 9.05
Here is a table giving information on all of the targets that we proposed in Cycles 1 and 2. (This table can be used with the maps that follow, to see exactly where we have chosen to look, in terms of dust environment.)
 9.06
First, for the Southern Galactic Hemisphere, here is a Schlegel et al. histo-eqalized dust map showing those of our proposed GALEX targets that are in the southern galactic hemisphere, together with (black rectangles) the Voyager slit position for all our Voyager observations. Then, here is the same map, but with the dust E(B_V) map shown on a logarithmic scale.
 9.07
Second, for the Northern Galactic Hemisphere, here is a Schlegel et al. histo-eqalized dust map showing those of our proposed GALEX targets that are in the northern galactic hemisphere, together with (black rectangles) the Voyager slit position for all our Voyager observations. Then, here is the same map, but with the dust E(B_V) map shown on a logarithmic scale.
 9.08
In the preceding maps, pay special attention to our Target Seven. Notice that it is at fairly high galactic latitude, BUT it has LOTS OF DUST. This is the target that is going to reveal whether or not the background radiation we see is extragalactic.

In the Next Section we will return to the question of what exactly it is that we are detecting: in particular, could it just be the instrumentally-scattered light of bright stars in the field?
