The Inner Structure of LambdaCDM Halos III: Universality and Asymptotic Slopes
Julio F. Navarro, Eric Hayashi, Chris Power +6
We investigate the mass profile of LambdaCDM halos using a suite of numerical simulations spanning five decades in halo mass, from dwarf galaxies to rich galaxy clusters. Our analy…
The Inner Structure of LCDM Halos II: Halo Mass Profiles and LSB Rotation Curves
E. Hayashi, J. F. Navarro, C. Power +6
We use a set of high-resolution cosmological N-body simulations to investigate the inner mass profile of galaxy-sized cold dark matter (CDM) halos. These simulations extend the tho…
Optical identification of the companion to PSR J1911-5958A, the pulsar binary in the outskirts of NGC 6752
C. G. Bassa, F. Verbunt, M. H. van Kerkwijk +1
We report on the identification of the optical counterpart of the binary millisecond pulsar PSR J1911-5958A, located in the outskirts of the globular cluster NGC 6752. At the posit…
Accurate Internal Proper Motions of Globular Clusters
L. R. Bedin, G. Piotto, J. Anderson +1
We have undertaken a long term program to measure high precision proper motions of nearby Galactic globular cluster (GC) stars using multi-epoch observations with the WFPC2 and the…
Chandra and XMM-Newton observations of the first quasars: X-rays from the age of cosmic enlightenment
C. Vignali, W. N. Brandt, D. P. Schneider +6
We report on Chandra and XMM-Newton observations of a sample of 13 quasars at z~4.7-5.4 mostly taken from the Sloan Digital Sky Survey (SDSS). The present sample complements previo…
