Neutral Clouds Within the Local X-ray Plasma
Abstract
We present new results based on the analysis of ROSAT PSPC observations towards nearby neutral clouds. These clouds are detectable as deep soft X-ray absorption features within the 1/4 keV energy band. Towards one of these clouds, optical absorption line measurements determine an upper distance limit of D <= 60 pc. The presented data suggest that this filament is only a part of a much more extended local-cloud structure. Here we demonstrate that we most probably detected a local neutral atomic hydrogen ``wall'' in the direction of a low-velocity arc.
