FUSE Observations of Interstellar and Intergalactic Absorption Toward the X-ray Bright BL Lac Object Mrk 421
B. D. Savage, B. P. Wakker, A. J. Fox +1
High-quality Far-Ultraviolet Spectroscopic Explorer (FUSE) observations at 20 km /s resolution of interstellar and intergalactic absorption from 910 to 1187 A are presented for the…
Searching for the Missing Baryons in the Warm-hot Intergalactic Medium
P. Richter, B. D. Savage, T. M. Tripp +1
We discuss physical properties and the baryonic content of the Warm-hot Intergalactic Medium (WHIM) at low redshifts. Cosmological simulations predict that the WHIM contains a larg…
Exploring Hot Gas in the Galactic Halo and High Velocity Clouds
Kenneth R. Sembach, Bart P. Wakker, Blair D. Savage +1
In the five years since its launch, the Far Ultraviolet Spectroscopic Explorer has given the astronomical community a marvelous glimpse into the realm of previously unexplored regi…
High-velocity OVI in and near the Milky Way
Bart P. Wakker, Blair. D. Savage, Kenneth R. Sembach +2
The Far Ultraviolet Spectroscopic Explorer (FUSE) has observed over three hundred fifty sightlines to extragalactic targets. About one hundred fifty of these are of sufficient qual…
Physical Properties and Baryonic Content of Low-Redshift Intergalactic Ly-alpha and O VI Absorption Systems: The PG1116+215 Sight Line
Kenneth R. Sembach, Todd M. Tripp, Blair D. Savage +1
We present HST and FUSE observations of the intergalactic absorption toward PG1116+215 in the 900-3000 A spectral region. We detect 25 Ly-alpha absorbers at rest-frame equivalent w…
C II Radiative Cooling of the Diffuse Gas in the Milky Way
N. Lehner, B. P. Wakker, B. D. Savage
The heating and cooling of the interstellar medium allow the gas in the ISM to coexist at very different temperatures in thermal pressure equilibrium. The heating cannot be directl…
