Detection of optical emission from the supernova remnant G7.7-3.7
V. Domček, J. V. Hernández Santisteban, A. Chiotellis +6
We present the first optical study of the supernova remnant (SNR) G7.7-3.7, with the aim of determining its evolutionary phase since it has been suggested to be the remnant of SN 3…
Host galaxy magnitude of OJ 287 from its colours at minimum light
Mauri J. Valtonen, Lankeswar Dey, S. Zola +54
OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…
The Supernova Remnant Populations of the galaxies NGC 45, NGC 55, NGC 1313, NGC 7793: Luminosity and Excitation Functions
M. Kopsacheili, A. Zezas, I. Leonidaki +1
We present a systematic study of the Supernova Remnant (SNR) populations in the nearby galaxies NGC 45, NGC 55, NGC 1313, and NGC 7793 based on deep Ha and [S II] imaging. We find…
Discovery of optical candidate supernova remnants in Sagittarius
J. Alikakos, P. Boumis, P. E. Christopoulou +1
During an [O III] survey for planetary nebulae, we identified a region in Sagittarius containing several candidate Supernova Remnants and obtained deep optical narrow-band images a…
A new candidate supernova remnant G 70.5+1.9
F. Mavromatakis, P. Boumis, J. Meaburn +1
A compact complex of line emission filaments in the galactic plane has the appearance of those expected of an evolved supernova remnant though non-thermal radio and X-ray emission…
Discovery of optical emission from the supernova remnant G 32.8-0.1 (Kes 78)
P. Boumis, E. M. Xilouris, J. Alikakos +4
Deep optical CCD images of the supernova remnant G 32.8-0.1 were obtained where filamentary and diffuse emission was discovered. The images were acquired in the emission lines of H…
