Abstract We calculate the elliptic flow of bottomonia produced in Pb $$$$\,+\,$$$$ $+$ Pb collisions at $$$$\sqrt{s_{\mathrm{NN}}}=5.02$$$$ $\sqrt{s_{\mathrm{NN}}}=5.02$  TeV. We consider temperature-dependent decay widths for the anisotropic escape of various bottomonium states and observe that the transverse momentum dependence of bottomonia elliptic flow provides a tomographic information about the QGP fireball at different stages of its evolution. For the space-time evolution of the fireball, we employ simulation results from the 3 + 1 D quasiparticle anisotropic hydrodynamic model. We find that our results for transverse momentum dependence of bottomonia elliptic flow are in reasonable agreement with experimental results from the ALICE and CMS collaborations.
