Revisiting hypervelocity stars after Gaia DR2
Douglas Boubert, James Guillochon, Keith Hawkins +3
Hypervelocity stars are intriguing rare objects traveling at speeds large enough to be unbound from the Milky Way. Several mechanisms have been proposed for producing them, includi…
Modelling Shock Heating in Cluster Mergers: I. Moving Beyond the Spherical Accretion Model
Ian G. McCarthy, Richard G. Bower, Michael L. Balogh +6
(Abridged) The thermal history of the intracluster medium (ICM) is complex. Heat input from cluster mergers, AGN, and galaxy winds offsets and may even halt the cooling of the ICM.…
The Hamburg/ESO R-process Enhanced Star survey (HERES) III. HE 0338-3945 and the formation of the r+s stars
K. Jonsell, P. S. Barklem, B. Gustafsson +4
We have derived abundances of 33 elements and upper limits for 6 additional elements for the metal-poor ([Fe/H] = -2.42) turn-off star HE 0338-3945 from high-quality VLT-UVES spect…
An analytic investigation of the scatter in the integrated X-ray properties of galaxy groups and clusters
Michael L. Balogh, Arif Babul, G. Mark Voit +4
(Abridged) We revisit the scaling relationships between the dark matter mass and observed X-ray luminosity and temperature of galaxy clusters and groups in the local Universe. Spec…
The Metallicity Distribution Function of the Halo of the Milky Way
Timothy C. Beers, Norbert Christlieb, John E. Norris +8
We report on the distribution of metallicities, [Fe/H], for very metal-poor stars in the halo of the Galaxy. Although the primary information on the nature of the Metallicity Distr…
High Redshift X-Ray Selected Quasars: CXOCY J125304.0-090737 joins the club
F. J. Castander, E. Treister, T. J. Maccarone +4
We present a new X-ray selected high redshift quasar CXOCY J125304.0-090737 at z=4.179, discovered by the Calan-Yale Deep Extragalactic Research (CYDER) Survey. This quasar is the…
