Proposal Title: Galaxy observations by the ''Hands on the Universe'' undergraduate class at
UW­Madison
ABSTRACT:
''Hands on the Universe'' is a lab­based class for non­science majors at UW­Madison. We have 5 class sections,
each with about 20 students. The final class lab (planned for early Dec 2011) explores the Hubble flow by obtaining
computer­simulated optical observations of galaxies. We would like to request 5 hours of Arecibo time to conduct
remotely complementary radio observations. We plan to use ON/OFF observing method and target bright galaxies
which need a few minutes of integration time. We will ftp data files and run them through a data reduction
pipeline, producing galaxy spectra essentially in real time. Students will then measure the recessional velocity for
each galaxy and add these ''real observations'' to their Hubble graphs of simulated galaxies. We have experience in
conduction remote observations with students and this to be highly motivational and exciting exercise for students.
