Within the pseudo‐complex general relativity (GR), a simulation of accretion disks for SgrA* is performed at the frequency of 250 GHz as used by the Event Horizon Telescope. Differences from the standard theory of GR are pointed out, such as the presence of a dark ring followed by an inner bright ring. In the second part, the interpretation of the source of the gravitational wave event GW150914, observed a year ago, is reanalyzed. Further comments are made on the observation of pulsations in NGC7793 P13.
