NuSTAR observation of GRO J1744-28 at low mass accretion rate
O. König, F. Fürst, P. Kretschmar +8
We present the spectral analysis of the LMXB GRO J1744-28 using 29 ks of NuSTAR data taken in 2017 February at a low luminosity of erg/s (3-50 keV). The c…

High-Precision Determination of Oxygen-K Transition Energy Excludes Incongruent Motion of Interstellar Oxygen
M. A. Leutenegger, S. Kühn, P. Micke +25
We demonstrate a widely applicable technique to absolutely calibrate the energy scale of x-ray spectra with experimentally well-known and accurately calculable transitions of highl…

Observation of strong two-electron--one-photon transitions in few-electron ion
Moto Togawa, Steffen Kühn, Chintan Shah +22
We resonantly excite the series of O and O up to principal quantum number with monochromatic x rays, producing -shell holes, and observe their relaxatio…
