Radiative electron capture as a tunable source of highly linearly polarized x-rays
M. Vockert, G. Weber, H. Bräuning +27
The radiative electron capture (REC) into the K shell of bare Xe ions colliding with a hydrogen gas target has been investigated. In this study, the degree of linear polarization o…
Observation of Non-Exponential Orbital Electron Capture Decays of Hydrogen-Like Pr and Pm Ions
Yu. A. Litvinov, F. Bosch, N. Winckler +37
We report on time-modulated two-body weak decays observed in the orbital electron capture of hydrogen-like Pr and Pm ions coasting in an ion storage…
Particle hydrodynamics with tessellation techniques
S. Hess, V. Springel
Lagrangian smoothed particle hydrodynamics (SPH) is a well-established approach to model fluids in astrophysical problems, thanks to its geometric flexibility and ability to automa…
The XMM-SSC survey of hard-spectrum XMM-Newton sources 1: optically bright sources
M. J. Page, I. Lehmann, Th. Boller +15
We present optical and X-ray data for a sample of serendipitous XMM-Newton sources that are selected to have 0.5-2 keV vs 2-4.5 keV X-ray hardness ratios which are harder than the…
Measurement of the $β^+$ and orbital electron-capture decay rates in fully-ionized, hydrogen-like, and helium-like Pr ions
Yu. A. Litvinov, F. Bosch, H. Geissel +39
We report on the first measurement of the $β^+$- and orbital electron capture decay rates of Pr nuclei with the most simple electron configurations: bare nuclei, hydrogen-…
Imaging Jupiter's radiation belts down to 127 MHz with LOFAR
J. N. Girard, P. Zarka, C. Tasse +71
Context. Observing Jupiter's synchrotron emission from the Earth remains today the sole method to scrutinize the distribution and dynamical behavior of the ultra energetic electron…
