Astrophysics Seminar meets in room 358 VAN on Tuesdays from 12:30 pm - 1:30 pm.
The format is either Astrophysics Journal club or a research presentation. Journal club papers for the current week are listed at VoxCharta (select University of Iowa). Everyone is encouraged to briefly review the selected papers before seminar. Moderators are expected to provide cookies.

A Deep Chandra View of M51 (K. D. Kuntz, Johns Hopkins University)
Chandra has made deep studies of four nearby galaxies; M101, M33, M83, and, most recently, M51. In each case the study is relatively uniform out to the D25 radius. Given the failing soft response, it is unlikely that comparable studies of other galaxies will be made with Chandra. I will review the recent point-source population study of M51 where I argue that the concept of universal luminosity functions needs to be reconsidered. I will then use our data from M101, M83 and M51 to address what I think we are beginning to learn about the diffuse X-ray emission from normal late-type spiral galaxies.
