ABSTRACT A study of gas-phase element abundances reported in the literature for 17
different elements sampled over 243 sight lines in the local part of our Galaxy reveals that …

The model of a Local Hot Bubble has been widely accepted as providing a framework that
can explain the ubiquitous presence of the soft X-ray background diffuse emission. We …

Using high-resolution ultraviolet spectra of 16 low-z QSOs obtained with the E140M echelle
mode of the Space Telescope Imaging Spectrograph, we study the physical conditions and …

The signature of 60Fe in deep-sea crusts indicates that one or more supernovae exploded
in the solar neighbourhood about 2.2 million years ago,,,. Recent isotopic analysis is …

We use spherically symmetric hydrodynamic simulations to study the dynamical evolution
and internal structure of superbubbles (SBs) driven by clustered supernovae (SNe), focusing …

Aims. We present new high resolution (R> 50 000) absorption measurements of the NaI
doublet (5889-5895 Å) along 482 nearby sight-lines, in addition to 807 new measurements …

We report on the observed properties of the plasma revealed through high signal-to-noise
observations of 54 intervening O vi absorption systems containing 85 O vi and 133 H i …

We present the first results from our NASA Keck Observatory Database of Ionized Absorbers
toward Quasars (KODIAQ) survey which aims to characterize the properties of the highly …

To probe the distribution and physical characteristics of interstellar gas at temperatures
T\approx 3\times 10^{5} K in the disk of the Milky Way, we have used the Far Ultraviolet …

We present a new unbiased search and analysis of all B stars in the solar neighbourhood
(within a volume of 400 pc diameter) using the Arivel data base to track down the remains of …
