•Old: HW#2 returned.
Some small issues, but overall I am pretty happy with the effort.
–Discuss assumptions in first problem, different data,
inclination
–For the Coma problems, more thought into discussions,
about all the assumptions,
the dark matter, stars, gas, etc.
–Pretty nice overall.
–Discuss the pros/cons of the galaxy spectrum modeling as
currently implemented. Also, what of the redshift
business?
•
•New: for several problems you will need to run a galaxy
simulator described in the
hand-out from Caroll & Ostlie’s appendix H. There is a Windows based implementation that can be downloaded
from http://tnewton.solarbotics.net/galaxy.html which you should get and verify ASAP.
I will demonstrate in class.
–Also, five parts to a scientific article.
