CO luminosity functions for far-infrared- and B-band-selected galaxies and the first estimate for Omega(H I+H2)
surveys molecules
2014/12/24
We derive a nonparametric CO luminosity function using an FIR- and an optical B-band-selected sample of the galaxies included in the FCRAO Extragalactic CO Survey. The FIR-selected sample is defined u...
The influence of Omega(b) on high-redshift structure
formation large scale structure of the Universe
2014/12/24
We analyze high-redshift structure in three hydrodynamic simulations that have identical initial conditions and cosmological parameters and differ only in the value of the baryon density parameter, Ωb...
Manganese evolution in Omega Centauri: a clue to the cluster formation mechanisms?
nuclear reactions nucleosynthesis abundances – galaxies: evolution – globular clusters: individual: ω Centauri
2011/10/18
We model the evolution of manganese relative to iron in the progenitor system of the globular cluster Omega Centauri by means of a self-consistent chemical evolution model. We use stellar yields that ...

2011/10/20
We measured temperatures, gravities, and masses for a large sample of blue horizontal branch stars in omega Centauri, comparing the results with theoretical expectations for canonical and He-enriched ...
Catastrophic quenching in alpha-Omega dynamos revisited
Catastrophic quenching alpha-Omega revisited
2011/9/27
At large magnetic Reynolds numbers, magnetic helicity evolution plays an important role in astrophysical large-scale dynamos. The recognition of this fact led to the development of the dynamical alpha...
