New Planetary Nebulae in the Northern Galactic Plane
Panayotis Boumis, Myfanwy Bryce
We present deep Halpha+[N II] CCD images of selected new Planetary Nebulae (PNe) discovered through an [O III] 5007 A emission line survey in the Galactic Bulge region with l > 0 d…
Multi-wavelength study of the G 82.2+5.3 supernova remnant
F. Mavromatakis, B. Aschenbach, P. Boumis +1
We present the first CCD flux-calibrated images of the snr G 82.2+5.3 in major optical emission lines. The [O III] 5007 line provides the first direct evidence of optical emission…
The faint supernova remnant G 34.7-0.4 (W44)
Fotis Mavromatakis, Panayotis Boumis, Christos D. Goudis
Flux calibrated images of the known supernova remnant G 34.7-0.4 in basic optical emission lines are presented. The low ionization images show a relatively flat flux distribution.…
