| "Loop I, one of elephants in the gamma-ray sky" |
| Seminar Title | The MESSIER surveyor: lifting the veil on the ultra-low surface brightness universe | | | | | Speaker: | Dr. HUANG Xiaoyuan | | | | | Affiliation: | (Bohr Institute) | | | | | When | Wednesday morning, Apr. 25, 10:30 a.m | | | | | Where: | Room 311, No.3 building , Xianlin campus (PMO, CAS) | | | Welcome to Attend | | | | | ( PMO Academic Committee & Academic Circulating committee) | | | Abstract: Loop I is one of bright extended sources in the gamma-ray sky. The origin of Loop I is still an unresolved question. We analyze 9 years of the Fermi LAT pass 8 data to study the morphology and spectrum of Loop I and compare with observations in other wavelength. We also use a leptonic model to make a broadband fitting and compare the required spectrum with local measurement. The local source scenario with betatron acceleration may be excluded. |
