Coulomb crystallization of xenon highly charged ions in a laser-cooled Ca+ matrix
Leonid Prokhorov, Aaron A. Smith, Mingyao Xu +17
We report on the sympathetic cooling and Coulomb crystallization of xenon highly charged ions (HCIs) with laser-cooled Ca ions. The HCIs are produced in a compact electron beam…

A "Black Hole Star" Reveals the Remarkable Gas-Enshrouded Hearts of the Little Red Dots
Rohan P. Naidu, Jorryt Matthee, Harley Katz +48
The physical processes that led to the formation of billion solar mass black holes within the first 700 million years of cosmic time remain a puzzle. Several theoretical scenarios…
