Improved analysis of time delays between radio wavelengths and X-ray of Sgr A* flares in the shock oscillation model
Researchers improved a shock oscillation model for Sgr A* by adding Compton scattering to predict time delays between radio and X-ray flares. The model successfully predicted specific delay times between different flare types, showing good agreement with observations. This suggests the delays are caused by sound waves traveling through the accretion flow.
