Abstract

We present detection of 64 H II regions, three superbubbles and two optical supernova remnant (SNR) candidates in the nearby irregular galaxy NGC 2366. The SNR candidates were detected by applying [S II]/H? 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? and [S II] fluxes for detected objects across the two fields of view in the 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.

通过窄带Hα和[SII]滤光片对附近星系NGC 2366的光学观测。超新星残余状态

我们在附近的不规则星系NGC 2366中探测到64个H II区域、三个超级气泡和两个光学超新星遗迹（SNR）候选者。通过应用[S II]/H？与保加利亚罗镇国家天文台2米RCC望远镜观测结果的比值标准。在本文中，我们报告了坐标，直径，H？以及在NGC 2366星系的两个视场中被探测物体的[S II]通量。使用档案XMM-Newton观测，我们提出了两种光学SNR候选者的可能X射线对应物。此外，我们放弃了对该星系中先前两个无线电SNR候选者的分类，因为它们似乎是背景星系。
