Dark matter scaling relations and the assembly epoch of Coma early-type galaxies
J. Thomas, R. P. Saglia, R. Bender +5
Axisymmetric, orbit-based dynamical models are used to derive dark matter scaling relations for Coma early-type galaxies. From faint to bright galaxies halo core-radii and asymptot…
Dynamical modelling of luminous and dark matter in 17 Coma early-type galaxies
J. Thomas, R. P. Saglia, R. Bender +5
Dynamical models for 17 Coma early-type galaxies are presented. The galaxy sample consists of flattened, rotating as well as non-rotating early-types including cD and S0 galaxies w…
The Star-Forming Torus and Stellar Dynamical Black Hole Mass in the Seyfert 1 Nucleus of NGC3227
R. Davies, J. Thomas, R. Genzel +7
We report R~4300 VLT SINFONI adaptive optics integral field K-band spectroscopy of the nucleus of the Seyfert 1 galaxy NGC3227 at a spatial resolution of 0.085" (7pc). We present t…
SINFONI's take on Star Formation, Molecular Gas, and Black Hole Masses in AGN
R. Davies, R. Genzel, L. Tacconi +3
We present some preliminary (half-way) results on our adaptive optics spectroscopic survey of AGN at spatial scales down to 0.085arcsec. Most of the data were obtained with SINFONI…
HST STIS spectroscopy of the triple nucleus of M31: two nested disks in Keplerian rotation around a Supermassive Black Hole
Ralf Bender, John Kormendy, Gary Bower +12
We present HST spectroscopy of the nucleus of M31 obtained with STIS. Spectra taken around the CaT lines at 8500 see only the red giants in the double bright- ness peaks P1 and P2.…
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…
