The CaT strength in Seyfert nuclei revisited: analyzing young stars and non-stellar light contributions to the spectra

L. R. Vega, N. V. Asari, R. Cid Fernandes +4

In a former paper (Garcia-Rissmann et al. 2005; hereafter Paper I), we have presented spectra of 64 active, 9 normal and 5 Starburst galaxies in the region around the near-IR Calci…

Fossil Groups in the Millennium Simulation. Evolution of the Brightest Galaxies

Eugenia Diaz-Gimenez, Hernan Muriel, Claudia Mendes de Oliveira

We create a catalogue of simulated fossil groups and study their properties, in particular the merging histories of their first-ranked galaxies. We compare the simulated fossil gro…

On the relationship between environment and galaxy properties in clusters of galaxies

Hector J. Martinez, Valeria Coenda, Hernan Muriel

We study the correlation between different properties of bright (L>L*) galaxies in clusters and the environment in the Sloan Digital Sky Survey (SDSS). Samples of clusters of galax…

Compact groups from the Millennium Simulations: I. Their Nature and the completeness of the Hickson sample

Eugenia Diaz-Gimenez, Gary Mamon

We identify compact groups of galaxies (CGs) within mock galaxy catalogues from the Millennium Simulation at z=0 with three semi-analytic models (SAMs) of galaxy formation. CGs are…

Stability and mode analysis of solar coronal loops using thermodynamic irreversible energy principles II. Modes in twisted non--isothermal magnetic field configurations

A. Costa, R. Gonzalez

We study the stability and the modes of non -- isothermal coronal loop models with different intensity values of the equilibrium twisted magnetic field.We use an energy principle o…

An MHD Gadget for cosmological simulations

K. Dolag, F. A. Stasyszyn

Various radio observations have showed that the hot atmospheres of galaxy clusters are magnetized. However, our understanding of the origin of these magnetic fields, their implicat…
