Abstract (from CDS):

The North Galactic Pole Rift (NGPR) is one of the few distinct neutral hydrogen clouds at high Galactic latitudes that have well-defined distances. It is located at the edge of the Local Cavity (LC) and provides an important test case for understanding the Local Hot Bubble (LHB), the presumed location for the hot diffuse plasma responsible for much of the observed keV emission originating in the solar neighborhood. Using data from the ROSAT All-Sky Survey and the Planck reddening map, we find the path length within the LC (LHB plus Complex of Local Interstellar Clouds) to be 98±27 pc, in excellent agreement with the distance to the NGPR of 98±6 pc. In addition, we examine another 14 directions that are distributed over the sky where the LC wall is apparently optically thick at keV. We find that the data in these directions are also consistent with the LHB model and a uniform emissivity plasma filling most of the LC.
