Luminosity functions of LMXBs in Centaurus A: globular clusters versus the field
R. Voss, M. Gilfanov, G. R. Sivakoff +16
We study the X-ray luminosity function (XLF) of low mass X-ray binaries (LMXB) in the nearby early-type galaxy Centaurus A, concentrating primarily on two aspects of binary populat…
Cepheid Calibrations of Modern Type Ia Supernovae:Implications for the Hubble Constant
Adam G. Riess, Lucas Macri, Weidong Li +9
This is the first of two papers reporting measurements from a program to determine the Hubble constant to 5% precision from a refurbished distance ladder. We present new observatio…
The Anisotropic Spatial Distribution of Hypervelocity Stars
Warren R. Brown, Margaret J. Geller, Scott J. Kenyon +1
We study the distribution of angular positions and angular separations of unbound hypervelocity stars (HVSs). HVSs are spatially anisotropic at the 3-sigma level. The spatial aniso…
Hypervelocity Stars and the Galactic Center
Warren R. Brown
A summary of the current knowledge on hypervelocity stars (HVSs). HVSs are fascinating because their properties are linked to Sgr A* and the stellar environment of the Galactic Cen…
HVS7: a chemically peculiar hyper-velocity star
N. Przybilla, M. F. Nieva, A. Tillich +3
Context: Hyper-velocity stars are suggested to originate from the dynamical interaction of binary stars with the supermassive black hole in the Galactic centre (GC), which accelera…
MMT Extremely Metal Poor Galaxy Survey I. An Efficient Technique to Identify Metal Poor Galaxies
Warren R. Brown, Lisa J. Kewley, Margaret J. Geller
We demonstrate a successful strategy for identifying extremely metal poor galaxies. Our preliminary survey of 24 candidates contains 10 metal poor galaxies of which 4 have 12+log(O…
