Kerr-MOG accretion disk spectra are softer than Kerr at fixed spin due to outward ISCO shift from the fifth-force parameter α, with an observational upper limit α < 0.044 from LMC X-1 data.
Derives partial-wave scalar absorption in Klein-Gordon separable Johannsen spacetimes and identifies finite-frequency spectra as a probe of radial propagation sectors beyond area law and null capture.
