This talk focuses on how such corrections may appear in observable quantities, including quasinormal modes, null geodesics, black hole shadows, periodic orbits, and gravitational waves. Particular attention is given to how small changes in the underlying geometry can modify orbital dynamics and leave imprints on the phase and amplitude of gravitational-wave signals. These signatures may provide a way to test noncommutative effects through future gravitational-wave observations.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"<p>Ciclo de Col\u00f3quios 2026.2 Col\u00f3quio #01 &#8220;How Can We Trace Noncommutativity?
