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…
Is the Galactic submillimeter dust emissivity underestimated?
K. M. Dasyra, E. M. Xilouris, A. Misiriotis +1
We present detailed modeling of the spectral energy distribution (SED) of the spiral galaxies NGC 891, NGC 4013, and NGC 5907 in the far-infrared and submm wavelengths. The model t…
The faint supernova remnant G 116.5+1.1 and the detection of a new candidate remnant
F. Mavromatakis, P. Boumis, E. M. Xilouris +2
The extended supernova remnant G 116.5+1.1 was observed in the optical emission lines of Halpha+[N II], [S II] and [O III]; deep long-slit spectra were also obtained. The morpholog…
Modelling the dust content of spiral galaxies: More dust mass vs. enhanced dust grain emissivity
K. M. Dasyra, E. M. Xilouris, A. Misiriotis +1
We present detailed modelling of the spectral energy distribution (SED) of the spiral galaxies NGC 891, NGC 4013, and NGC 5907 in the far-infrared (FIR) and sub-millimeter (submm)…
Dust in a merging galaxy sequence: the SCUBA view
A. Georgakakis, E. M. Xilouris, A. Misiriotis +1
We investigate the cold and warm dust properties during galaxy interactions using a merging galaxy sample ordered into a chronological sequence from pre- to post-mergers. Our sampl…
