SUMMARY OF SEQUENCE NUMBER 970473
Title: ORIGIN OF THE GALACTIC RIDGE X-RAY EMISSION
Observer: EBISAWA
Subject Category: Diffuse Emission and Surveys
Seq: 970473 ObsId: 01523
Long-term Plan bin: 22-Feb-2000
ABSTRACT
Origin of the Galactic Ridge X-ray Emission (GRXE) is unknown yet. The most controversial issue is if GRXE is truly diffuse emission or composed of numerous point sources. The first imaging observation of GRXE above 2 keV with ASCA could not clearly answer to this question, being limited by the ASCA XRT spatial resolution (HPD~3 arcmin). With AXAF, having much superior spatial resolution, we will be unambiguously give the answer, being able to detect point sources with a luminosity of ~4x10^{32} erg s^{-1} at 10 kpc. If GRXE is truly diffuse emission, the interstellar magnetic reconnection is proposed as a mechanism to heat and confine the hot plasma. We may observe diffuse X-rays distribute along locally intensified magnetic fields, as observed in the Solar flares.
