Spectral characteristics of water megamaser galaxies II: ESO 103-G035, TXS 2226-184, and IC 1481
Nicola Bennert, Hartmut Schulz, Christian Henkel
Long-slit optical emission-line spectra of the H2O megamaser galaxies ESO 103-G03, TXS 2226-184, and IC 1481 are evaluated in order to look for characteristics typical for water-me…
Winds and Outflows in Starburst Galaxies and AGN
Stefanie Komossa, Guenther Hasinger, Hartmut Schulz
Winds and outflows in starburst galaxies and AGN provide important information on the physics of the "central engine", the presence and evolution of (nuclear) starbursts, and the m…
Rotation and outflow in the central kiloparsec of the water megamaser galaxies IC 2560, NGC 1386, NGC 1052, and Mrk 1210
H. Schulz, C. Henkel
Optical emission-line profiles were evaluated in order to explore the structure of galactic nuclei containing H2O megamaser sources. Galactic rotation and outflow of narrow-line ga…
Size and Structure of the Narrow-Line Region of Quasars
Nicola Bennert, Heino Falcke, Hartmut Schulz +2
We have observed the narrow-line regions (NLRs) of the seven brightest radio-quiet PG (or BQS) quasars (z < 0.5) with the Wide Field and Planetary Camera 2 on board the Hubble Spac…
Incompatibility of a comoving Ly-alpha forest with supernova-Ia luminosity distances
Jens Thomas, Hartmut Schulz
Recently Perlmutter et al. suggested a positive value of Einstein's cosmological constant Lambda on the basis of luminosity distances from type-Ia supernovae. However, Lambda world…
Classification of multifluid CP world models
Jens Thomas, Hartmut Schulz
Various classification schemes exist for homogeneous and isotropic (CP) world models, which include pressureless matter (so-called dust) and Einstein's cosmological constant Lambda…
