Large-Scale Structure at z~2.5
G. M. Williger, C. Hazard, J. A. Baldwin +1
We have made a statistically complete, unbiased survey of C IV systems toward a region of high QSO density near the South Galactic Pole using 25 lines of sight spanning …
High Resolution Observations of the QSO BR1202-0725: Deuterium and Ionic Abundances at Redshifts Above z=4
E. J. Wampler, G. M. Williger, J. A. Baldwin +3
We present results from 12 km/s resolution echelle spectroscopy of the bright QSO BR1202-0725. A preliminary analysis shows that high metallicity narrow line absorption c…
The Single-Degenerate Scenario for Type Ia SNe in Cosmic Perspective
R. Canal, P. Ruiz-Lapuente, A. Burkert
The occurrence and properties of Type Ia supernovae (SNe Ia) in single-degenerate binary systems (white dwarf [WD] + nondegenerate companion) is examined for galaxies of different…
Constraints on massive black holes as dark matter candidates using Galactic globular clusters
Ralf Klessen, Andreas Burkert
This work considers the idea of massive black holes being the constituents of the Galactic dark matter halo. It constrains the maximum black hole mass to $\mbh \sil 5 \times 10^4 \…
Fragmentation in a centrally condensed protostar
Andi Burkert, Peter Bodenheimer
Hydrodynamical calculations in three space dimensions of the collapse of an isothermal, centrally condensed, rotating 1 M\sol protostellar cloud are presented. A numerical algorith…
The Structure of Dark Matter Haloes in Dwarf Galaxies
A. Burkert
Recent observations indicate that dark matter haloes have flat central density profiles. Cosmological simulations with non-baryonic dark matter predict however self similar haloes…
