|Title:||Optical observations of the nearby galaxy NGC 2366 through narrowband Hα and [Sii] filters. Supernova remnants status||Journal:||Serbian Astronomical Journal||Issue:||198||First page:||13||Last page:||23||Issue Date:||1-Jan-2019||Rank:||M23||ISSN:||1450-698X||DOI:||10.2298/SAJ190131003V||Abstract:||
We present detection of 64 Hii 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]/Hα 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, Hα 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.
