Query: Constraints on new physics from radiative $B$ decays   A new phase for the measurements of radiative decay modes in $b \to s$
transitions has started with new measurements of exclusive modes by LHCb and
with Belle-II showing distinctive promises in both inclusive and exclusive
channels. After critically reviewing the hadronic uncertainties in exclusive
radiative decays, we analyze the impact of recent measurements of the branching
ratio and mass-eigenstate rate asymmetry in $B_s\to\phi\gamma$ and of the
angular distribution of $B\to K^*e^+e^-$ at low $q^2$ on new physics in the
$b\to s\gamma$ transition.
