Description
J2004+3252 is an extended source (~2° extension) listed in the 1LHAASO catalog. Based on four years of LHAASO observations, we decompose this complex region into three distinct sub-sources. One of them, J1959+3518, is spatially coincident with Cygnus X-1. For J1958+3017, we identify associated CO and HI gas distributions, along with two SNRs in its vicinity. Additionally, the third sub-source, J2010+3245, is surrounded by CO and HI and hosts the young stellar cluster FSR 0189.
In this presentation, we will compare the performance of the multi-source template fitting with the single extended-source template. Besides, we will show the fitting results with the optimized cut condition that improve the analysis significance. Furthermore, we will discuss the multi-wavelength study of the region to explore the possible physical origins and emission mechanisms of these sub-sources.
