Testing Black Holes with Interstellar Missions: II. Flyby Probes
Yi Fan, Cosimo Bambi, Leda Gao +2
Recently, we demonstrated that while an interstellar mission to the nearest black hole remains highly speculative and extraordinarily challenging, it is not entirely implausible wi…
Testing non-circular black hole spacetime with X-ray reflection
Leda Gao, Swarnim Shashank, Cosimo Bambi
X-ray reflection spectroscopy is a powerful tool for testing the Kerr hypothesis and probing the strong gravity regime around accreting black holes. Most tests of General Relativit…
Testing Black Holes with Interstellar Missions: I. Orbiting Probes
Leda Gao, Cosimo Bambi, Yi Fan +3
Recently, we showed that the possibility of an interstellar mission to the closest black hole, while highly speculative and extremely challenging, is not completely unrealistic wit…
Searching for Isolated Black Hole Candidates within 15 pc of the Solar System in Gaia DR3
Abdurakhmon Nosirov, Cosimo Bambi, Leda Gao +4
Theoretical models predict that the Galaxy hosts - black holes formed from the complete gravitational collapse of heavy stars and that most of these black holes are iso…
