Testing a class of non-Kerr metrics with hot spots orbiting SgrA
Dan Liu, Zilong Li, Cosimo Bambi
SgrA, the supermassive black hole candidate at the Galactic Center, exhibits flares in the X-ray, NIR, and sub-mm bands that may be interpreted within a hot spot model. Light c…
Distinguishing black holes and wormholes with orbiting hot spots
Zilong Li, Cosimo Bambi
The supermassive black hole candidates at the center of every normal galaxy might be wormholes created in the early Universe and connecting either two different regions of our Univ…
Constraints on the spacetime geometry around 10 stellar-mass black hole candidates from the disk's thermal spectrum
Lingyao Kong, Zilong Li, Cosimo Bambi
In a previous paper, one of us has described a code to compute the thermal spectrum of geometrically thin and optically thick accretion disks around generic stationary and axisymme…
Constraining the spin and the deformation parameters from the black hole shadow
Naoki Tsukamoto, Zilong Li, Cosimo Bambi
Within 5-10 years, very-long baseline interferometry (VLBI) facilities will be able to directly image the accretion flow around SgrA, the super-massive black hole candidate at…
Testing the nature of the supermassive black hole candidate in SgrA* with light curves and images of hot spots
Zilong Li, Lingyao Kong, Cosimo Bambi
General relativity makes clear predictions about the spacetime geometry around black holes. In the near future, new facilities will have the capability to explore the metric around…
