“…Observations of this quasar [249][250][251][252][253][254][255][256][257][258][259][260][261][262], which is at a distance of 3 billion of light years, showed that it con sists of two radio sources of different intensities that are receding from each other such that, according to estimates of [254,255,261,262], the velocity of their separation exceeds the speed of light by an order of magnitude. Several different explanations of this phe nomenon have been put forward.…”

“…For example, in [251,261] (see also review [252]), it was suggested that the motion of objects consisting of real tachyons is being observed. (It is interesting to note that hypothe ses of this kind are considered to the present day [253].) The authors of [259] even developed a theory of superluminal magnetic dipole radiation created by charged particles moving with ultrarelativistic veloci ties in the magnetic field of the quasar.…”

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 optical medium, in particular, in vacuum, gives rise to impact radiation, which later was termed the Vavilov-Cherenkov radiation. Shortly after the development of Special Relativity, some researchers considered the possibility of superluminal motion. In 1923, the Soviet physicist L.Ya. Strum sug gested the existence of tachyons, which, however, have not been discovered yet. Superluminal motions can occur only for images, e.g., for so called "light spots," which were considered in 1972 by V.L. Ginzburg and B.M. Bolotovskii. These spots can move with a superluminal phase velocity but are incapable of transferring energy and information. Nevertheless, these light spots may induce quite real generation of microwave radi ation in closed waveguides and create the Vavilov-Cherenkov radiation in vacuum. In this work, we consider various paradoxes, illusions, and artifacts associated with superluminal motion.

“…1 does not imply a low redshift, as there is no intergalactic absorption of the tachyon flux. Tachyonic γ-rays are not attenuated by cosmic background photons, as tachyons and photons can only indirectly interact via matter fields [28,29,31].…”

“…The electron temperature can be inferred from the exponential cutoff, β = m/(kT ) or kT [keV] ≈ 511/β. We consider ultra-relativistic multi-component plasmas in the collisionless regime [27], in stationary non-equilibrium described by power law densities [28,29].…”

Evidence for superluminal radiation in γ-ray burst (GRB) spectra is pointed out. The spectral maps of GRB 941017, GRB 990123, and GRB 990104 are analyzed. The superluminal radiation modes are generated by the shock-heated ultra-relativistic source plasma. The tachyonic radiation field is a real Proca field with negative mass-square, coupled to the electron gas by a frequency-dependent fine-structure constant. At GeV energies, the coupling constant approaches a limit value, so that the radiation field is minimally coupled to the electron current. In the soft γ-ray band, the interaction with the GRB plasma becomes nonlocal, due to the varying coupling strength depending on the energy of the radiated modes. The spectral fitting with tachyonic flux densities generated by nonlocal plasma currents is explained. Estimates of the tachyonic luminosity, temperature, and internal energy of the electronic source plasma are obtained from the spectral fits.

Evidence for superluminal radiation from TeV blazars is pointed out. Spectral fits of the BL Lacertae objects W Comae, 1ES 2344 + 514, PG 1553 + 113, and 1ES 0806 + 524 are performed with tachyonic γ-ray cascades generated by the thermal electron plasma in the galactic nuclei. The transversal and longitudinal radiation components as well as the thermodynamic parameters of the ultra-relativistic electron populations are extracted from the spectral maps based on EGRET, VERITAS, MAGIC, and HESS flux data. An extended spectral plateau typical for tachyonic γ-ray spectra emerges in the MeV and low GeV range, terminating in exponential decay without a power law crossover. Thermal tachyonic cascade spectra are also predicted for Fermi blazars. By comparing to other TeV γ-ray sources such as Galactic supernova remnants and pulsar wind nebulae as well as active galactic nuclei, the curvature in the high-energy spectral slopes of BL Lacertae objects is shown to be intrinsic, i.e. uncorrelated with distance.
