Prior to the development of Special Relativity, no restrictions were imposed on the velocity of the motion of particles and material bodies, as well as on energy transfer and signal propagation. At the end of the 19th century and the beginning of the 20th century, it was shown that a charge that moves at a velocity faster than the speed of light in an ...

Superluminal motion in astronomy
European Journal of Physics, 2001Several examples of `intrinsic-type' superluminal motion in astronomy are taken. A simple signal-delay transformation is devised and shown to be sufficient to explain the superluminal effect as resulting from differential signal delay across an expanding source. The distinction between relativistic motion and relativistic kinematics is made.

Superluminal Motion and Polarization in Blazars
Chinese Journal of Astronomy and Astrophysics, 2004A relativistic beaming model has been successfully used to explain the observed properties of active galactic nuclei (AGNs). In this model there are two emission components, a boosted one and an unbeamed one, shown up in the radio band as the core and lobe components.

Temporal Parts and Superluminal Motion
Philosophical Papers, 2003Hud Hudson has recently suggested a scenario intended to show that, assuming the doctrine of temporal parts and a sufficiently liberal view of composition, there are material objects that move faster than light. I accept Hudson's conditional but contend that his modus ponens is less plausible than the corresponding modus tollens.

Emission accompanying superluminal motion of light
Journal of Soviet Laser Research, 1990We hope that we have succeeded in demonstrating the great scientific interest that attaches to superluminal motions of charges and to investigation of the radiation accompanying these motions. An extensive literature on superluminal motion is on hand even now.

Superluminal motion in compact radio sources
Publications of the Astronomical Society of the Pacific, 1980The observations of radio sources whose components appear to move superluminally are now sufficient to eliminate certain theoretical models. However, a number of models might be still relevant. The models which involve relativistic bulk motions of the radio components seem to provide the most likely explanation of apparent superluminal motion.

5 Superluminal Motion and Superluminal Causation
2005AbstractThis chapter shows that once one adopts certain principles of composition and decomposition, a popular view of persistence, and a highly-intuitive sufficient condition for motion, one can show that there are many material objects that move much faster than light.

Superluminal motions in special relativity
Mysteries, puzzles, and paradoxes in quantum mechanics, 1999Some recent experiments, performed at Berkeley, Cologne, Florence and Vienna led to the claim that something seems to travel with a speed larger than the speed c of light in vacuum. Various other experimental results seem to point in the same direction: For instance, localized wavelet-type solutions of Maxwell equations have been found, both ...

Superluminal motion and the acceleration model
Chinese Astronomy and Astrophysics, 1997Abstract A relativistic beaming model with acceleration is used to analyze the optical magnitudes and radio flux densities of 48 superluminal sources. The results not only support the beaming model but also indicate that the acceleration model is reasonable.
