Laboratory measurements compellingly support charge-exchange mechanism for the 'dark matter' 3.5 keV X-ray line
Chintan Shah, Stepan Dobrodey, Sven Bernitt +4
The reported observations of an unidentified X-ray line feature at 3.5 keV have driven a lively discussion about its possible dark matter origin. Motivated by this, we have m…
Strong higher-order resonant contributions to x-ray line polarization in hot plasmas
Chintan Shah, Pedro Amaro, Rene Steinbrügge +6
We studied angular distributions of x rays emitted in resonant recombination of highly charged iron and krypton ions, resolving dielectronic, trielectronic, and quadruelectronic ch…
Polarization measurement of dielectronic recombination transitions in highly charged krypton ions
Chintan Shah, Holger Jörg, Sven Bernitt +10
We report linear polarization measurements of x rays emitted due to dielectronic recombination into highly charged krypton ions. The ions in the He-like through O-like charge state…
