The X-ray variability and the near-IR to X-ray spectral energy distribution of four low luminosity Seyfert 1 galaxies
I. E. Papadakis, Z. Ioannou, W. Brinkmann +1
We present the results from a study of the X-ray variability and the near-IR to X-ray spectral energy distribution of four low-luminosity, Seyfert 1 galaxies. We compared their var…
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 distribution of the ISM in the Milky Way A three-dimensional large-scale model
A. Misiriotis, E. M. Xilouris, J. Papamastorakis +2
We use the COBE/DIRBE (1.2, 2.2, 60, 100, 140, and 240 m) maps and the COBE/FIRAS spectra (for the wavelength range 100 - 1000 m) to constrain a model for the spatial distrib…
New Planetary Nebulae in the Galactic Bulge region with l>0deg - II
P. Boumis, S. Akras, E. M. Xilouris +4
The presentation of new results from an [O III] 5007 A survey in a search for planetary nebulae (PNe) in the galactic bulge is continued. A total of 60 objects, including 19 new PN…
B and I-band optical micro-variability observations of the BL Lac objects S5 2007+777 and 3C371
E. M. Xilouris, I. E. Papadakis, P. Boumis +5
We have observed S5 2007+777 and 3C371 in the B and I bands for 13 and 8 nights, respectively, during various observing runs in 2001, 2002 and 2004. The observations resulted in al…
Deep optical observations of the supernova remnants G 126.2+1.6, G 59.8+1.2 and G 54.4-0.3
P. Boumis, F. Mavromatakis, E. M. Xilouris +3
Optical CCD imaging and spectroscopic observations of three supernova remnants are presented. Optical emission from G 54.4-0.3 and G 59.8+1.2 is detected for the first time, while…
