Correlating few keV Energetic Neutral Atoms with soft x-rays
Abstract
The discovery of a bright 'ribbon' of Energetic Neutral Atom (ENA) emission by the Interstellar Boundary Explorer (IBEX) was both unexpected and exciting. Although there are a number of theories about the origin of this structure, none of them fully work, and the ribbon is still a puzzle. The ribbon is brightest at a few keV, which begs the question of whether it is visible in photons. Under a Science Innovation Fund grant at GSFC, we have performed detailed numeric correlation of the energetic data from IBEX and soft x-rays from ROSAT and present preliminary results from this study including upper limits on x-ray emission associated with the ENA ribbon. Figure 1: Energetic neutral atom emission map from IBEX in galactic coordinates. The energy range is 0.9 - 1.5 keV.
