First optical detection from the supernova remnant G 15.1-1.6
P. Boumis, J. Alikakos, P. E. Christopoulou +3
Deep optical CCD images of the supernova remnant G 15.1-1.6 were obtained and filamentary and diffuse emission has been discovered. The images, taken in the emission lines of Halph…
The global kinematics of the Dumbbell planetary nebula (NGC 6853, M27, PN G060.8-03.6)
J. Meaburn, P. Boumis, P. E. Christopoulou +3
Spatially resolved profiles of the HeII 6560 A, Halpha and [N II] 6548 & 6584 A nebular emission lines have been obtained in two orthogonal long cuts over the Dumbbell planetary ne…
Deep Halpha imagery of the Eridanus shells
P. Boumis, C. Dickinson, J. Meaburn +5
A deep \ha image of interlocking filamentary arcs of nebulosity has been obtained with a wide-field ( 30\degree diameter) narrow-band filter camera combined with a CCD as…
Evidence for an outflow from the Seyfert galaxy NGC 4051
P. E. Christopoulou, A. J. Holloway, W. Steffen +6
New observations using narrow band imaging, long-slit spectroscopy and MERLIN observations of the nuclear region of the Seyfert galaxy NGC~4051 have been made. An edge brightened,…
