The Spatial Distribution of the Galactic First Stars I: High-Resolution N-body Approach
Evan Scannapieco, Daisuke Kawata, Chris B. Brook +3
We study the spatial distribution of Galactic metal-free stars by combining an extremely high-resolution (7.8 X 10^5 solar masses per particle) Cold Dark Matter N-body simulation o…
Revision of VLT/UVES constraints on a varying fine-structure constant
Michael T. Murphy, John K. Webb, Victor V. Flambaum
We critically review the current null results on a varying fine-structure constant, alpha, derived from VLT/UVES quasar absorption spectra, focusing primarily on the many-multiplet…
Intracluster light and the extended stellar envelopes of cD galaxies: An analytical description
Marc S. Seigar, Alister W. Graham, Helmut Jerjen
We have analysed deep R-band images, down to a limiting surface brightness of 26.5 R-mag arcsec (equivalent to ~28 B-mag arcsec), of 5 cD galaxies to determine the sh…
Field Deployment of Prototype Antenna Tiles for the Mileura Widefield Array--Low Frequency Demonstrator
Judd D. Bowman, David G. Barnes, Frank H. Briggs +22
Experiments were performed with prototype antenna tiles for the Mileura Widefield Array--Low Frequency Demonstrator (MWA-LFD) to better understand the widefield, wideband propertie…
Two Disk Components from a Gas Rich Disk-Disk Merger
Chris Brook, Simon Richard, Daisuke Kawata +2
We employ N-body, smoothed particle hydrodynamical simulations, including detailed treatment of chemical enrichment, to follow a gas-rich merger which results in a galaxy with disk…
Absence of HI in the Bootes Dwarf Spheroidal Galaxy
Jeremy Bailin, Alyson Ford
Neutral hydrogen observations towards the Bootes dwarf spheroidal galaxy, a very low luminosity metal-poor Galactic satellite, were obtained using the Parkes Radio Telescope. We do…
