摘 要 (Abstract): Recently the Event Horizon Telescope has presented a ring-like emission structure of M87 and our galactic center Sgr A* at 1.3mm with unprecedented angular resolutions. These images are consistent with the size and shape of the lensed photon orbit encircling the “shadow” of a supermassive black hole.  In this talk, I would like to overview the theoretical interpretation of EHT results of M87 and Sgr A* and discuss the possibility of the alternatives to a black hole for the central compact object.
