Gravitational Wave Signatures from Periodic Orbits around a Non--commutative Schwarzschild Black Hole
Non-commutative corrections move periodic orbits inward, lower the energy needed for a given orbit shape, and generate gravitational waves with phase shifts plus higher amplitude; a bound Θ/M² < 0.014 is extracted from the S2 star's periastron advance.

Gravitational emissions and light curves of quasi-periodic orbits in Schwarzschild spacetime embedded in a Dehnen-type dark matter halo
Dark matter halo parameters amplify the scale of closed timelike orbits in Schwarzschild spacetime, inducing phase lags in gravitational waves while light curves retain distinguishable peaks for certain orbital features.
