摘要:

我们在附近的不规则星系NGC 2366中探测到67个HII区和两个光学超新星遗迹(SNR)候选者。通过将[SII]/H $α$比率标准应用于保加利亚罗真国家天文台2米RCC望远镜的观测,检测了SNR候选者。本文报道了NGC 2366星系中两个视场内探测到的天体的坐标、直径、H $α$和[SII]通量。使用档案XMM-牛顿观测,我们建议可能的X射线对应的两个光学SNR候选人。此外,我们放弃了两个以前的无线电信噪比候选人在这个星系的分类,因为它们似乎是背景星系。

英文摘要:

We present detection of 67 HII regions and two optical supernova remnant (SNR) candidates in the nearby irregular galaxy NGC 2366. The SNR candidates were detected by applying [SII]/H$α$ ratio criterion to observations made with the 2-m RCC telescope at Rozhen National Astronomical Observatory in Bulgaria. In this paper we report coordinates, diameters, H$α$ and [SII] fluxes for detected objects across the two fields of view in NGC 2366 galaxy. Using archival XMM-Newton observations we suggest possible X-ray counterparts of two optical SNR candidates. Also, we discard classification of two previous radio SNR candidates in this galaxy, since they appear to be background galaxies.
