With roughly 200 scientists, 200 technicians, observers, engineers, and programmers, and 200 administrative support staff members, the Harvard-Smithsonian Center for Astrophysics (CfA) has the potential to be imposing and impersonal...
...within this casual setting, scientists are taking on some serious scientific challenges. The CfA's facilities include labs, machine shops, fully networked VAX and Sun computers, and the 60,000 volume astronomical library...
...delighted to have been chosen to develop this center," said Dr. Irwin I. Shapiro, director of the Harvard-Smithsonian Center for Astrophyics (CFA), in a news release dated March 25. "Especially because the broad range of astrophysical research already in progress at the CFA provides the potential for important interdisciplinary collaborations." The observatory is a member of the CFA...
...scientists, AXAF will offer two advances over current x-ray telescopes. According to Harvey Tananbaum, associate director at CFA, the new telescope "will be able to take sharper pictures, detecting fainter, more distant sources." Also, AXAF will remain in orbit for 15 years, in contrast to current telescopes, which function for only a year...
...meantime, the CfA study will go on, and other mapping efforts are in the works. "Big as it is," Geller explains, "our survey area compared with the visible universe is like Rhode Island compared with the surface of the earth." The bubbles and walls could be isolated phenomena. But, notes Geller: "Every survey ever done has contained structures as big as the survey could contain." If that trend continues, then there are larger objects yet to be found, which will give theorists even worse headaches. "These surveys test in the most acute way our conceptions of how structure developed...
