We review the recent noticeable progresses in black hole physics focusing on the up-coming super-collider, the LHC. We discuss the classical formation of black holes by particle collision, the greybody factors for higher dimensional rotating black holes, the deep implications of black hole physics to the ‘energy-distance’ relation, the security issues of the LHC associated with black hole forma...

We explicitly compute the causal structure of the Schwarzschild black hole spacetime, by providing an algorithm to decide if any pair of events is causally related. The primary motivation for this study comes from discrete quantum gravity, in particular the causal set approach, in which the fundamental variables can be thought of as the causal ordering of randomly selected events in spacetime. ...

In models with large extra dimensions, particle collisions with center-of-mass energy larger than the fundamental gravitational scale can generate nonperturbative gravitational objects. Since cosmic rays have been observed with energies above 108 TeV, gravitational effects in the TeV energy range can, in principle, be observed by ultrahigh energy cosmic ray detectors. We consider the interactio...

Signatures of black hole events at CERN’s Large Hadron Collider are discussed. Event simulations are carried out with the Fortran Monte Carlo generator CATFISH. Inelasticity effects, exact field emissivities, color and charge conservation, corrections to semiclassical black hole evaporation, gravitational energy loss at formation and possibility of a black hole remnant are included in the analy...

ABSTRACT Stars can be tidally destroyed or swallowed by supermassive black hole binaries (SMBHBs). Using a large number of few-body simulations, we investigate the enhancement and suppression full partial disruption direct capture events hard SMBHBs with wide ranges key parameters, i.e. primary BH mass ($M_{\rm BH, 1}= 10^{5}{-}10^{8}\, {\rm M}_{\odot }$), binary ratio (10?3–1), semimajor axis ...

If MACHOs are black holes of mass ∼0.5 M,, they must have been formed in the early universe when the temperature was ∼1 GeV. We estimate that in this case in our Galaxy’s halo out to ∼ 50 kpc there exist ∼5 # black hole binaries the coalescence times of which are comparable to the age of the universe, so that the 8 10 coalescence rate will be ∼ events yr per galaxy. This suggests that we can ex...
