eROSITA ISM investigation via X-ray shadowing

Not scheduled




Dr Michael Freyberg (MPE)


Since the ROSAT era X-ray shadows cast by opaque molecular cloud onto distant soft X-ray emission are an useful tool to disentangle the 3d-structure along the line-of-sight, when comparing on-cloud and off-cloud spectra.
Here we report on initial X-ray shadowing results obtained from data taken during the eROSITA pointed observation phase, before the start of the all-sky surveys.
We outline the analysis procedure (in particular background handling) and compare our findings with corresponding observations from the ROSAT all-sky survey and from XMM-Newton.
