The Distance and Interstellar Sight Line to Gx 339 – 4
The distance to the black hole binary GX 339–4 remains a topic of debate. We examine high-resolution optical spectra of the Na D lines resolving the velocity structure along the line of sight. We find this to be complex, with at least nine components, mostly blue-shifted, spanning a velocity range of nearly 200 km s −1. The presence of components with a large blue-shift rules out a nearby locat...
متن کاملLine-of-Sight Reddening Predictions: Zero Points, Accuracies, the Interstellar Medium, and the Stellar Populations of Elliptical Galaxies
Revised (B-V)0-Mg2 data for 402 elliptical galaxies are presented which are used to test reddening predictions. These reddening predictions can also tell us both what the intrinsic errors are in this relationship among gE galaxy stellar populations, as well as details of nearby structure in the interstellar medium (ISM) of our Galaxy and of the intrinsic errors in reddening predictions. Using l...
متن کاملLine-of-Sight Percolation
Given ω ≥ 1, let Z2(ω) be the graph with vertex set Z 2 in which two vertices are joined if they agree in one coordinate and differ by at most ω in the other. (Thus Z2(1) is precisely Z .) Let pc(ω) be the critical probability for site percolation in Z2(ω). Extending recent results of Frieze, Kleinberg, Ravi and Debany, we show that limω→∞ ωpc(ω) = log(3/2). We also prove analogues of this resu...
متن کاملTwo Lines of Sight with Exceedingly Anomalous Uv Interstellar Extinction
Low resolution IUE data obtained towards HD 62542, a B5 V star in a line of sight associated with a dark cloud in the Gum Nebula region near & Pup (OS Iaf) and y Vel (WC8 + 09 I), yields an extinction curve with an extremely broad and weak W extinction bump and the highest far-UV extinction yet obseaved in the Milky Way, reaching a value of E(1200-V)/E(B-v)p115. The weak bump is very similar to...
