SOAP and the Interstellar Froth
R. Tuellmann, M. R. Rosa, R. -J. Dettmar
We investigate, whether the alleged failure of standard photoionization codes of the Diffuse Ionized Gas (DIG) is simply caused by geometrical effects and the insufficient treatmen…

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…
