Query: Shining X-rays on asymptotically safe quantum gravity   Asymptotically safe quantum gravity is a promising candidate scenario to
provide a UV extension for the effective quantum field theory of Einstein's
gravity. The theory has its foundations on the very successful framework of
quantum field theory, which has been extensively tested for electromagnetic and
nuclear interactions. However, observational tests of asymptotically safe
quantum gravity are more challenging. Recently, a rotating black hole metric
inspired by asymptotically safe quantum gravity has been proposed, and this
opens the possibility of astrophysical tests of the theory. In the present
paper, we show the capabilities of X-ray reflection spectroscopy to constrain
the inverse dimensionless fixed-point value $\gamma$ from the analysis of a
Suzaku observation of the X-ray binary GRS 1915+105. We compare these
constraints with those obtained from black hole imaging.
