Lab Exercise 9
X-Ray Sources
Read Section 9.9 and answer Question 18 with this
figure.
Figure 9.18: Uhuru X-ray sources. The first X-Ray satellite, Uhuru, produced
this map of x-ray point sources in the 1970's. (Uhuru is a Swahili word meaning
"Freedom") The size of the dots represent how bright the sources are in
x-rays. Is there only one distribution of X-rays or are there two distributions?
