The third law of black hole thermodynamics and the mass-to-charge ratio of scalar fields
Shahar Hod, Tsvi Piran
Kehle and Unger have recently shown that self-gravitating charged classical scalar fields can collapse to form extremal Reissner-Nordström (eRN) black holes in finite time, thus vi…
The third law of black hole thermodynamics: Quantum versus classical considerations
Shahar Hod, Tsvi Piran
Kehle and Unger have recently shown that, under suitable conditions, a massless charged classical scalar field can produce an extremal black hole in finite time. This result appear…
Superdiffusion at the Galactic Centre
Pau Amaro Seoane, Kostas Tzanavaris, Reinhard Genzel +14
Tracking S-star cluster orbits around Sgr A* calibrates orbital transport models for space-borne gravitational wave detectors. Standard kinetic theories model this cluster via loca…
Stellar rotation of S301 as a macroscopic gyroscope to test general relativity
Pau Amaro Seoane, Xian Chen, Alejandro Torres-Orjuela +16
Stellar trajectories around the Galactic Center provide a testing environment for general relativity. The intrinsic rotation of these stars evolves under covariant transport in cur…
S301 and friends: Measuring the spin of Sgr A*
T. Piran, P. Amaro-Seoane, B. Aytac +15
The discovery of S301 (GRAVITY Collaboration et al., 2026) with pericenter distance rp= 280rg and eccentricity e=0.9825, opens the prospect of measuring the spin parameter of Sgr A…
The Origin of the Magnetic Flux Driving TDE Jets
Nimrod Tripto, Julian Krolik, Tsvi Piran
Tidal Disruption Events (TDEs) occur when a star approaches a black hole closely enough to be torn apart by tidal forces, after which the stellar debris begins to orbit the black h…
