Late Time Spectrum of SN 1987A
| Author | |
| Abstract |
At late times (200 days), when the photosphere of continuum emission has disappeared from the envelope, the radiation of the supernova 1987A is powered by $\gamma$-rays resulting from 56Co decays. The spectrum formation at such a late time is a highly non-linear process (XU [1]). The $\gamma$-ray photons first lose their energy due to Compton scattering and photoelectric absorption, generating non-thermal energetic electrons. These energetic electrons are then slowed down by Coulomb scattering or ionizing and exciting different ions in the envelope. The ions will recombine and de-excite, radiating away their energy in infrared (IR), optical and primarily ultraviolet (UV) wavebands. |

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.
