Subject: SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION            
  Title: QUEST FOR THE ORIGIN OF THE GALACTIC DIFFUSE X-RAYS WITH ASCA AND XTE           


Abstract:
 In spite that the Galactic diffuse X-ray emission is the most energetic constituent
 in the interstellar space, its origin, probably diffuse in nature, is still unknown.
 ASCA spectra exhibited numerous emission lines expected from thermal plasmas, and
 more importantly, there was an indication that the plasma becomes cooler going far
 from the Galactic plane. This suggests the thermal plasma is dynamic and
 continuously outflowing from the Galactic plane. We propose three pointings at l=0
 toward the positive latitudinal direction, where we will carry out scanning
 observations with XTE. By combining ASCA and XTE data, we will study spectral variations parpendicular to the Galactic plane.
