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…
Attempt to explain black hole spin in X-ray binaries with new physics
Cosimo Bambi
It is widely believed that the spin of black holes in X-ray binaries is mainly natal. A significant spin-up from accretion is not possible. If the secondary has a low mass, the bla…
High energy collision of two particles in wormhole spacetimes
Naoki Tsukamoto, Cosimo Bambi
We study the collision of two particles in the Teo wormhole spacetime, in which the wormhole is stationary and axisymmetric. We show that a non-rotating Teo wormhole cannot be a pa…
Constraining the Cardoso-Pani-Rico metric with future observations of SgrA
Cosimo Bambi
SgrA, the supermassive black hole candidate at the center of our Galaxy, seems to be one of the most promising object to test the Kerr black hole hypothesis with near future ob…
Note on the Cardoso-Pani-Rico parametrization to test the Kerr black hole hypothesis
Cosimo Bambi
The construction of a generic parametrization to describe the spacetime geometry around astrophysical black hole candidates is an important step to test the Kerr black hole hypothe…
Note on the effect of a massive accretion disk in the measurements of black hole spins
Cosimo Bambi, Daniele Malafarina, Naoki Tsukamoto
The spin measurement of black holes has important implications in physics and astrophysics. Regardless of the specific technique to estimate the black hole spin, all the current ap…
