Two 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...
متن کاملDust obscuration studies along quasar sight lines using simulated galaxies
We use the results of a set of three–dimensional SPH–Treecode simulations which model the formation and early evolution of disk galaxies, including the generation of heavy elements by star formation, to investigate the effects of dust absorption in quasar absorption line systems. Using a simple prescription for the production of dust, we have compared the column density, zinc abundance and opti...
متن کاملObservations of Rotationally Resolved C3 in Translucent Sight Lines
The rotationally resolved spectrum of the A1 u X 1 g 000–000 transition of C3, centered at 4051.6 Å, has been observed along 10 translucent lines of sight. To interpret these spectra, a new method for the determination of column densities and analysis of excitation profiles involving the simulation and fitting of observed spectra has been developed. The populations of lower rotational levels (J...
متن کاملStatistics and characteristics of MgII absorbers along GRB lines of sight observed with VLT-UVES
We analyse the properties of Mg ii absorption systems detected along the sightlines toward GRBs using a sample of 10 GRB afterglow spectra obtained with VLT-UVES over the past six years. The signal-to-noise ratio is sufficiently high that we can extend previous studies to smaller equivalent widths (typically Wr > 0.3 Å). Over a pathlength of ∆z ∼ 14, we detect 9 intervening Mg ii systems with W...
متن کاملProbing the Intergalactic Medium with the Lyα forest along multiple lines of sight to distant QSOs
We present an effective implementation of analytical calculations of the Lyα opacity distribution of the Intergalactic Medium (IGM) along multiple lines of sight (LOS) to distant quasars in a cosmological setting. The method assumes that the distribution of neutral hydrogen follows that of an underlying dark matter density field and that the density distribution is a (local) lognormal distribut...
