Radiation reaction in weakly magnetized black holes: can the tail term be ignored in the strong field regime?
João S. Santos, Vitor Cardoso, José Natário
We study radiation from charged particles in circular motion around a Schwarzschild black hole immersed in an asymptotically uniform magnetic field. In curved space, the radiation…
Comment on "The Tully-Fisher law and dark matter effects derived via modified symmetries" by Arraut Ivan
L. Filipe O. Costa, F. Frutos-Alfaro, José Natário +1
It has been claimed in I. Arraut, 2023 EPL 144 29003 [arXiv:2311.05652] that General Relativity can generate effects equivalent to dark matter, based on a "new modified symmetry th…
Relativistic effects cannot explain galactic dynamics
L. Filipe O. Costa, José Natário
It has been suggested in recent literature that nonlinear and/or gravitomagnetic general relativistic effects can play a leading role in galactic dynamics, partially or totally rep…
Spherically symmetric elastic bodies in general relativity
Artur Alho, José Natário, Paolo Pani +1
The purpose of this review it to present a renewed perspective of the problem of self-gravitating elastic bodies under spherical symmetry. It is also a companion to the papers [Phy…
Scale invariant elastic stars in General Relativity
Artur Alho, José Natário, Paolo Pani +1
We present a model of relativistic elastic stars featuring scale invariance. This implies a linear mass-radius relation and the absence of a maximum mass. The most compact spherica…
Message in a bottle: energy extraction from bouncing geometries
Vitor Cardoso, João L. Costa, José Natário +1
Quantum gravity phenomenology suggests the interesting possibility that black holes are not eternal. Collapse could be halted by some unknown mechanism, or Hawking radiation might…
Reference frames in General Relativity and the galactic rotation curves
L. Filipe O. Costa, José Natário, F. Frutos-Alfaro +1
The physical interpretation of the exact solutions of the Einstein field equations is, in general, a challenging task, part of the difficulties lying in the significance of the coo…
Electromagnetic radiation reaction and energy extraction from black holes: The tail term cannot be ignored
João S. Santos, Vitor Cardoso, José Natário
We study electromagnetic radiation reaction in curved space and the dynamics of radiating charged particles. The equation of motion for such particles is the DeWitt-Brehme equation…
