Coulomb crystals in the harmonic lattice approximation

D. A. Baiko, D. G. Yakovlev, H. E. De Witt +1

The dynamic structure factor and the two-particle distribution function of ions in a Coulomb crystal are obtained in a closed analytic form u…

The Nose-hoover thermostated Lorentz gas

K. Rateitschak, R. Klages, W. G. Hoover

We apply the Nose-Hoover thermostat and three variations of it, which control different combinations of velocity moments, to the periodic Lorentz gas. Switching on an external elec…

The FIRST Bright Quasar Survey. II. 60 Nights and 1200 Spectra Later

R. L. White, R. H. Becker, M. D. Gregg +11

We have used the VLA FIRST survey and the APM catalog of the POSS-I plates as the basis for constructing a new radio-selected sample of optically bright quasars. This is the first…

An X-Ray Spectroscopic Study of the SMC X-1/Sk 160 System

Patrick S. Wojdowski, George W. Clark, Timothy R. Kallman

We have investigated the composition and distribution of the wind of Sk 160, the supergiant companion of the X-ray star SMC X-1, by comparing an X-ray spectrum of the source, obtai…

Evidence for the Hierarchical Formation of the Galactic Spheroid

Patrick Cote, Ronald O. Marzke, Michael J. West +1

The possibility that the Galactic spheroid was assembled from numerous chemically-distinct, proto-Galactic fragments is investigated using a Monte-Carlo technique designed to simul…

Clump Distance to the Magellanic Clouds and Anomalous Colors in the Galactic Bulge

Piotr Popowski

I demonstrate that the two unexpected results in the local Universe: 1) anomalous intrinsic (V-I)_0 colors of the clump giants and RR Lyrae stars in the Galactic center, and 2) ver…
