On the Formation of cD Galaxies and their Parent Clusters
H. M. Tovmassian, H. Andernach
In order to study the mechanism of formation of cD galaxies we search for possible dependencies between the K-band luminosity of cDs and the parameters of their host clusters which…
Relation between activity, morphology and environment for a large sample of SDSS galaxies
R. A. Ortega-Minakata, J. P. Torres-Papaqui, H. Andernach +2
We apply a stellar population synthesis code to the spectra of a large sample of SDSS galaxies to classify these according to their activity (using emission-line diagnostic diagram…
Preparing old and recent radio source tables for the VO age: Current status
H. Andernach
Independent of established data centers, and partly for my own research, I have been collecting the tabular data from nearly 1500 articles concerned with radio sources. Optical cha…
The Cluster M/L and the Value of Omega_m
H. Andernach, M. Plionis, O. L'opez-Cruz +2
From an up-to-date compilation of ACO cluster redshifts and velocity dispersions we extract a homogeneous sample of 459 clusters with robust velocity dispersion. Using the virial t…
