Query: Binary Pulsars as probes for Spin-2 Ultralight Dark Matter   Binary pulsars can be excellent probes of ultra-light dark matter. We
consider the scenario where the latter is represented by a spin-2 field. The
coherent oscillations of the dark matter field perturb the dynamics of binary
systems, leading to secular effects for masses that resonate with the binary
systems. For the range $10^{-23}$eV $\lesssim m \lesssim 10^{-17}$eV we show
that current timing data could potentially constrain the universal coupling
strength of dark matter to ordinary matter at the level of $\alpha \simeq
10^{-5}$.
