Black Hole Imaging as GR tests |
|
Abstract |
Einstein's General Relativity (GR) invented 100 years ago successfully describes gravitation. An algebraic extension of GR to pseudo-complex (pc) variables has been proposed, called pseudo-complex General Relativity (pc-GR). We have performed ray-tracing simulations based on the pc-GR theory and standard GR for Sgr A* for different accretion scenarios and viewing angles for the observer. The simulated pc-GR images are clearly different from GR ray-tracing images. This provides the strongest test of GR theories. In addition we have simulated Fe K line profiles for both theories. As pc-GR discs are brighter, the integrated line flux is larger in pc-GR. The line profiles are clearly different from standard GR. This offers a second robust measurement to test pc-GR versus GR. |
