MBM16\: Is the Galactic Halo Really MissingquestionMark

MBM16 is a dense molecular cloud at high Galactic latitude (l170,b38,d6095pc) whose absorption of the Xray background has been used to measure thestrength of the Galactic halo. Liu et al. has recently claimed that thebackground Xray emission towards MBM16 is not consistent with a significantGalactic halo and suggested that previous halo measurements using the nearbyMBM12 and MBM20 clouds are wrong. However, ROSAT measurements of these clouds dosuggest significant halo emission. Using a new observation strategy, we proposean observation of MBM16 that will measure the halo emission, settle thisapparent disagreement, and avoid the complication of solar wind chargeexchange. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
