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…
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…
Can we observationally test the weak cosmic censorship conjecture?
Lingyao Kong, Daniele Malafarina, Cosimo Bambi
In general relativity, gravitational collapse of matter fields ends with the formation of a spacetime singularity, where the matter density becomes infinite and standard physics br…
Gravitational blueshift from a collapsing object
Lingyao Kong, Daniele Malafarina, Cosimo Bambi
We discuss a counterintuitive phenomenon of classical general relativity, in which a significant fraction of the radiation emitted by a collapsing object and detected by a distant…
