The thermal and non-thermal gaseous halo of NGC5775
R. Tuellmann, R. -J. Dettmar, M. Soida +2
In this letter we present first results from spectroscopic observations of Diffuse Ionized Gas (DIG) in the halo of NGC5775 obtained with FORS1 attached to UT1/Antu of the Very Lar…

Spectroscopy of diffuse ionized gas in halos of selected edge-on galaxies
R. Tuellmann, R. -J. Dettmar
In order to examine the excitation and ionization mechanism of extraplanar diffuse ionized gas (DIG) we have obtained optical longslit spectra of seven edge-on spiral galaxies. In…

Extraplanar diffuse ionized gas in a small sample of nearby edge-on galaxies
J. Rossa, R. -J. Dettmar
We present narrowband H-alpha imaging data of a small survey of nearby edge-on spiral galaxies, aiming at the detection of `extraplanar' diffuse ionized gas (DIG). A few of our stu…
