论文摘要
我们已经使用了Voyager和Galex观测值来绘制银河赤道附近的弥漫性银河光。我们发现，大多数观测值相对较弱，表面亮度少于5,000个光子单元。这很重要，因为许多紫外线望远镜在低银河纬度上没有观察到，因为担心会出现明亮的弥散发射。我们的数据与星际尘埃的排放一致，反照率（$ a $）为0.2-0.3，相位功能（$ g $）$ <0.7 $ <0.7 $ $ <0.7 $； $ 0.2 <a <0.5; g <0.8 $1500Å; $ 0.4 <a <0.6; g <0.4 $2300Å。
We have used Voyager and Galex observations to map the diffuse Galactic light near the Galactic equator. We find that most of the observations are relatively faint with surface brightnesses of less than 5,000 photon units. This is important because many ultraviolet telescopes have not observed at low Galactic latitudes because of the fear of a bright diffuse emission. Our data are consistent with emission from interstellar dust grains with albedo ($a$) of 0.2 -- 0.3 and phase function ($g$) $ < 0.7$ at 1100 Å; $0.2 < a < 0.5; g < 0.8$ at 1500 Å; and $0.4 < a < 0.6; g < 0.4$ at 2300 Å.
