The ACS Virgo Cluster Survey X. Half-light radii of globular clusters in early-type galaxies: environmental dependencies and a standard ruler for distance estimation
(Astrophysical Journal, 2005-12-01)
We have measured half-light radii, rh, for thousands of globular clusters (GCs) belonging to the one hundred early-type galaxies observed in the ACS Virgo Cluster Survey and the elliptical galaxy NGC 4697. An analysis of ...
The nature of the HE0450-2958 system
(Blackwell Publishing, 2005-11-10)
Magain et al. (2005) argued that the host galaxy of the quasar in HE0450-2958 is substantially under-luminous given the likely mass of its nuclear black hole. Using kinematical information from the spectra of the quasar ...
Interaction of supermassive black holes with their stellar and dark matter environments
(Springer, 2005-06-22)
While supermassive black holes probably gained most of their mass via accretion
of gas, the galactic nuclei in which they are currently situated are dominated
by stars. This article reviews recent theoretical work on the ...
Dark matter dynamics and indirect detection
(Modern Physics Letters A, 2005-05-10)
Non-baryonic, or “dark”, matter is believed to be a major component of the total mass
budget of the universe. We review the candidates for particle dark matter and discuss
the prospects for direct detection (via interaction ...
