New Planetary Nebulae in the Galactic Bulge region with l>0deg - I. Discovery method and first results
Panayotis Boumis, Euthimios V. Paleologou, Fotis Mavromatakis +1
We present the first results of an [O III] 5007 A interference filter survey for Planetary Nebulae (PNe) in the Galactic bulge. Covering (at first) the 66 per cent of the survey ar…
Optical observations of the supernova remnant G 69.4+1.2
Fotis Mavromatakis, Panayotis Boumis, Euthimios V. Paleologou
We performed deep optical observations of the area of the new supernova remnant G 69.4+1.2 in the emission lines of [O III], Halpha+[N II] and [S II]. The low ionization images rev…
First optical light from the supernova remnant G 17.4-2.3
P. Boumis, F. Mavromatakis, E. V. Paleologou
Deep optical CCD images of the supernova remnant G 17.4-2.3 were obtained and faint emission has been discovered. The images, taken in the emission lines of Halpha+[N II], [S II] a…
The peculiar supernova remnant CTB 80
F. Mavromatakis, J. Ventura, E. V. Paleologou +1
Deep CCD exposures of the peculiar supernova remnant CTB 80 in the light of major optical lines have been obtained. These images reveal significant shock heated emission in the are…
The supernova remnants G67.7+1.8, G31.5-0.6 and G49.2-0.7
F. Mavromatakis, J. Papamastorakis, J. Ventura +3
Wide field CCD observations of three, less known, supernova remnants. Filamentary and diffuse emission is discovered from the supernova remnant G67.7+1.8. Emission can also be seen…
Are spiral galaxies optically thin or thick?
E. M. Xilouris, Y. I. Byun, N. D. Kylafis +2
The opacity of spiral galaxies is examined by modelling the dust and stellar content of individual galaxies. The model is applied to five late-type spiral galaxies (NGC 4013, IC 25…
