Query: Experimental observation of the geostrophic turbulence regime of rapidly
  rotating convection   The competition between turbulent convection and global rotation in planetary
and stellar interiors governs the transport of heat and tracers, as well as
magnetic-field generation. These objects operate in dynamical regimes ranging
from weakly rotating convection to the `geostrophic turbulence' regime of
rapidly rotating convection. However, the latter regime has remained elusive in
the laboratory, despite a worldwide effort to design ever-taller rotating
convection cells over the last decade. Building on a recent experimental
approach where convection is driven radiatively, we report heat transport
measurements in quantitative agreement with this scaling regime, the
experimental scaling-law being validated against direct numerical simulations
(DNS) of the idealized setup. The scaling exponent from both experiments and
DNS agrees well with the geostrophic turbulence prediction. The prefactor of
the scaling-law is greater than the one diagnosed in previous idealized
numerical studies, pointing to an unexpected sensitivity of the heat transport
efficiency to the precise distribution of heat sources and sinks, which greatly
varies from planets to stars.
