December 2 Karen Byrum (HEP) Astro-particle physics: new initiatives at Argonne

There has been tremendous growth in interest in astrophysics at Argonne over last several years, and this effort spans several divisions. Examples of current research include:
  • studies of presolar grains recovered from meteorites in MSD
  • HEP division participation in the Dark Energy Survey
  • measurements of nuclear masses, reaction rates, level widths, decay rates in PHY
  • theoretical studies of reaction properties of nuclei in PHY
  • theoretical work on properties of neutron star and strange star matter in PHY
  • constraints on dark matter in HEP
  • HEP efforts relating to Pierre Auger cosmic ray observatory
  • work on the VERITAS telescope for gamma-ray astronomy in HEP
  • efforts in nova and supernova simulation involving MCS
This list is not complete, but it gives an indication of the large amount and wide range of astrophysics activity at Argonne.

The purpose of these talks is get people together from across Argonne who are working in these and related areas, and encourage communication. We learn about relations between our research efforts, educate each other, and keep each other up to date on the latest news.

The format is informal, conducted over lunch, with a half-hour to one-hour presentation each time. Most speakers are from Argonne or the University of Chicago, but we also have talks from visitors to the lab and university. So as not to add much to the seminar load, meetings are held monthly, on the first Thursday of each month.
