Normal galaxies in the XMM-Newton fields. X-rays as a star formation indicator
E. Rovilos, I. Georgantopoulos, P. Tzanavaris +4
Context: We use the first XMM serendipitous source catalogue (1XMM) to compile a sample of normal X-ray galaxies Aims: We seek to expand the database of X-ray selected normal galax…
Abundant dust found in intergalactic space
E. Xilouris, P. Alton, J. Alikakos +3
Galactic dust constitutes approximately half of the elements more massive than helium produced in stellar nucleosynthesis. Notwithstanding the formation of dust grains in the dense…
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…
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…
Local and Large scale Environment of Seyfert Galaxies
E. Koulouridis, M. Plionis, V. Chavushyan +3
We present a three-dimensional study of the local (<100 h^-1} kpc) and the large scale (<1 h^{-1} Mpc) environment of the two main types of Seyfert AGN galaxies. For this purpose w…
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…
