Optical Observations of the Nearby Galaxy NGC 2366 Through Narrowband H_alpha and [SII] Filters. Supernova Remnants Status

Vučetić, M. M.; Onić, D.; Petrov, N. +2 more

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 [SII]Hα ratio criterion to observations made with the 2-m RCC telescope at Rozhen National Astronomical Observatory in Bulgaria. In this paper we report …

ASCA and XMM-Newton Observations of the Galactic Supernova Remnant G311.5-0.3

Filipović, M. D.; Maxted, N.; Wong, G. F. +4 more

We present an analysis of X-ray observations made with ASCA and XMM-Newton of the Galactic supernova remnant (SNR) G311.5-0.3. Prior infrared and radio observations of this SNR have revealed a shell-like morphology at both wavelengths. The spectral index of the radio emission is consistent with synchrotron emission, while the infrared colors are c…

Multifrequency Radio Observations of SNR J0536-6735 (N 59B) with Associated Pulsar

Bozzetto, L. M.; Stupar, M.; Crawford, E. J. +2 more

We present a study of new Australian Telescope Compact Array (ATCA) observations of supernova remnant, SNR J0536-6735. This remnant appears to follow a shell morphology with a diameter of D=36×29 pc (with 1 pc uncertainty in each direction). There is an embedded HII region on the northern limb of the remnant which made various analysis and measure…
