Iron He-triplet signatures of shocks in the hottest galaxy clusters. Z/W line ratio, line broadening, and electron-ion temperature equilibration
Eugene Churazov, Yuri Ralchenko, Ildar I. Khabibullin +5
A merger of clusters naturally drives shocks with Mach number in the intra-cluster medium (ICM). This process creates several distinct signatures, including…

Puzzling Isotonic Odd-Even Staggering of Charge Radii in Deformed Rare Earth Nuclei
Endre Takacs, Hunter Staiger, Steven A. Blundell +16
The nuclear charge radius is a fundamental observable that encodes key aspects of nuclear structure, deformation, and pairing. Isotonic (constant neutron number) systematics in the…

Extreme Ultraviolet Spectroscopy of Highly Charged Lu and Yb Ions for Nuclear Charge Radius Determination
Hunter Staiger, Endre Takacs, Steven A. Blundell +16
We report a high-precision determination of the natural-abundance-averaged nuclear charge-radius difference between Yb and Lu using extreme ultraviolet (EUV) spectroscopy of highly…
