Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We studied the hot gas in the Galactic halo in the direction of a blazer PKS 2155-304 (z = 0.117). This is the second direction for combined analysis using high resolution X-ray absorption/emission data. Absorption features of O(sub VII) and O(sub VIII) are measured with Chandra LETGS. Suzaku observations of the vicinity of PKS 2155-304 allows us to study emission lines (O(sub VII) , O(sub VIII) , N(sub VII) and N(sub EIX) ). We performed a joint analysis of emission and absorption data assuming a vertically exponential galactic disk. The gas temperature and density at the Galactic plane are determined to be 3.2(+0.7,-0.6) x 10(exp 6) K and 1.3(+0.4,-0.6) x 10(exp -3) cm(exp -3) and the scale heights of the gas temperature and density 2.2(+4.4,-2.1) kpc and 5.1(+3.9,-4.7) kpc, respectively., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574038, レポート番号: JAXA-SP-09-008E}, pages = {104--105}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Line-of-sight spatial extent of warm-hot medium in the direction of PKS 2155-304}, volume = {JAXA-SP-09-008E}, year = {2010} }
