An Xmm-newton Observation of the Local Bubble Using a Shadowing Filament in the Southern Galactic Hemisphere

Abstract

We present an analysis of the X-ray spectrum of the Local Bubble, obtained by simultaneously analyzing spectra from two XMM-Newton pointings on and off an absorbing filament in the Southern galactic hemisphere (b ≈ −45◦). We use the difference in the Galactic column density in these two directions to deduce the contributions of the unabsorbed foreground… (More)
