| Abstract |
The recent discovery by Fesen et al. [1] of the remnant of S Andromedae, the historic supernova of 1885 observed a mere 16\textacutedbl from the nuclear center of M31, brings to two the number of supernovae whose ejecta have been observed successfully in absorption: SN 1006 (Type Ia; Wu et al. [2]; Fesen et al. [3]; Hamilton and Fesen [4]) and now SN 1885 (Type I peculiar; de Vaucouleurs and Corwin [5]). In the discovery image, SN 1885 appears as an unresolved spot of Fe I absorption silhouetted against the starry blaze of M31 s bulge. From the observed absorption contrast, Fesen et al. [1] estimate that SN 1885 has an Fe I diameter of 0.3\textacutedbl, corresponding to an expansion velocity of \textpm5,000 km s—1. |

The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
