Blazars are believed to be an active galaxy with a relativistic jet that is pointed in the direction of the Earth.

A black hole that is accreting infalling matter can become active, emitting a strong wind through a collimated relativistic jet.

In both classes of source, the variable emission is believed to originate in a relativistic jet oriented close to the line of sight.

Polarization with coincident orientation has been observed in radio, infrared, and optical light being emitted from the large-scale jet ; these emissions are therefore almost certainly synchrotron in nature, radiation that is created by a jet of charged particles moving at relativistic speeds.

German-American astronomer Walter Baade found that the light from this jet is plane polarized, which suggested that the energy was being generated by the acceleration of electrons moving at relativistic velocities in a magnetic field.

A ' p ' suffix indicates a peculiar galaxy that does not fit cleanly into the classification scheme ; in this case, the peculiarity is caused by the presence of a relativistic jet emerging from the core.

Blazars are AGN with a relativistic jet that is pointing in the general direction of the Earth.

The observed emission from a blazar is greatly enhanced by relativistic effects in the jet, a process termed relativistic beaming.

A simple model of beaming however, illustrates the basic relativistic effects connecting the luminosity emitted in the rest frame of the jet, S < sub > e </ sub > and the luminosity observed on Earth, S < sub > o </ sub >.

The jet which is not approaching Earth will appear dimmer because of the same relativistic effects.

Alternate explanations for the relativistic jet / unified scheme approach which have been proposed include gravitational microlensing and coherent emission from the relativistic jet.

In the unified scheme of radio-loud active galactic nuclei, the observed nuclear phenomenology of BL Lacs is interpreted as being due to the effects of the relativistic jet that is closely aligned to the line of sight of the observer.

* Heber Curtis discovers a relativistic jet of matter emerging from Elliptical Galaxy M87.

A relativistic jet which extracts energy from the vicinity of what is believed to be a supermassive black hole at the center of the galaxy is responsible for emissions in the X-ray and radio wavelengths.

This is much larger than the observed size of 37 μas and so suggests that the Sagittarius A * radio emissions are not centered on the hole but arise from a bright spot in the region around the black hole, close to the event horizon, possibly in the accretion disc or a relativistic jet of material ejected from the disc.

Consequently, the jet bundle is now recognized as the correct domain for a geometrical covariant field theory and much work is done in general relativistic formulations of fields using this approach.

In mid 1979 a team led by David Roberts at the VLA ( Very Large Array ) near Socorro, New Mexico / USA discovered a relativistic jet emerging from quasar A with no corresponding equivalent in quasar B.

At first glance, the first paper seemed to point out a contradiction between the electrodynamic theory and the relativistic one concerning the calculation of the electromagnetic masses.

It turns out that such inconsistencies arise from relativistic wavefunctions having a probabilistic interpretation in position space, as probability conservation is not a relativistically covariant concept.

Finally, gravitational redshifts are a relativistic effect observed in electromagnetic radiation moving out of gravitational fields.

If the particles become fast enough that relativistic effects become important, the beam becomes out of phase with the oscillating electric field, and cannot receive any additional acceleration.

The infall of this material into a black hole drives a pair of relativistic jets out along the rotational axis, which pummel through the stellar envelope and eventually break through the stellar surface and radiate as gamma rays.

In 1996, Partha Ghose had presented a relativistic quantum mechanical description of spin-0 and spin-1 bosons starting from the Duffin – Kemmer – Petiau equation, setting out Bohmian trajectories for massive bosons and for massless bosons, thus also for photons.

Ununtrium has not yet been confirmed to be a poor metal and, due to relativistic effects, might not turn out to be one.

Only by separating out the positive and negative frequency parts does the equation describe a relativistic wavefunction.

From analysis of relativistic beaming effects, the jets of FRII sources are known to remain relativistic ( with speeds of at least 0. 5c ) out to the ends of the lobes.

His general relativistic theory of the Post-Newtonian reference frames which he had worked out along with Victor A. Brumberg, was adopted in 2000 by the resolutions of the International Astronomical Union as a standard for reduction of ground-based astronomical observation.

Many equations in relativistic physics appear far simpler when expressed in geometric units, because all appearances of G or c drop out.

In a nuclear reaction, the mass of the atoms that come out is less than the mass of the atoms that go in, and the difference in mass shows up as heat and light which has the same relativistic mass as the difference ( and also the same invariant mass in the center of mass frame of the system ).

However, in such a situation, although the container's total relativistic energy and total momenta increase, these energy and momentum increases subtract out in the invariant mass definition, so that the moving container's invariant mass will be calculated as the same value as if it were measured at rest, on a scale.

By contrast, MacIntyre is concerned with reclaiming various forms of moral rationality and argumentation that claim neither ultimate finality nor incorrigible certainty ( the mistaken project of the Enlightenment ), but nevertheless do not simply bottom out into relativistic or emotivist denials of any moral rationality whatsoever ( according to him, the mistaken conclusion of Nietzsche, Sartre and Stevenson ).

The central cluster galaxy contains a massive network of spectral line emitting filaments, which appear to be being dragged out by rising bubbles of relativistic plasma generated by the central active galactic nucleus.

* Sins of a Solar Empire, where starships go ' out of phase ' with the universe reducing the effect of relativistic mass.

) The probability of producing the resonance at a given energy E is proportional to f ( E ), so that a plot of the production rate of the unstable particle as a function of energy traces out the shape of the relativistic Breit – Wigner distribution.

However, since the aliens have no concept of the passage of time, they aren't realizing that each time they return their host — Trevor — home, they are returning him 10 years later each time ( due to the effects of relativistic time dilation ), putting him further out of touch with everything he loves.

So he pointed out the group characteristics of the transformation, and he corrected Lorentz's formulas for the transformations of charge density and current density ( which implicitly contained the relativistic velocity-addition formula, which he elaborated in May in a letter to Lorentz ).

Like energy and momentum, the invariant mass of isolated systems cannot be changed so long as the system remains totally closed ( no mass or energy allowed in or out ), because the total relativistic energy of the system remains constant so long as nothing can enter or leave it.

They may similarly be produced in regions like the center of the Milky Way and other galaxies, where very energetic celestial events occur ( principally the interaction of relativistic jets with the interstellar medium ).

We also note that a two-body Dirac equation composed of a Dirac operator for each of the two point particles interacting via the Coulomb interaction can be exactly separated in the ( relativistic ) center of momentum frame and the resulting ground state eigenvalue has been obtained very accurately using the Finite element methods of J. Shertzer.

The invariant mass is the relativistic mass of the system when viewed in the center of momentum frame.

In inertial reference frames other than the rest frame or center of mass frame, the equation E = mc² remains true if the energy is the relativistic energy and the mass the relativistic mass.

As seen from the center of momentum frame, the relativistic mass is also the invariant mass, as discussed above ( just as the relativistic energy of a single particle is the same as its rest energy, when seen from its rest frame ).

For other frames, the relativistic mass ( of a body or system of bodies ) includes a contribution from the " net " kinetic energy of the body ( the kinetic energy of the center of mass of the body ), and is larger the faster the body moves.

The invariant mass is calculated excluding the kinetic energy of the system as a whole ( calculated using the single velocity of the box, which is to say the velocity of the box's center of mass ), while the relativistic mass is calculated including invariant mass PLUS the kinetic energy of the system which is calculated from the velocity of the center of mass.

The relativistic mass is the mass of the system as it would be measured on a scale, but in some cases ( such as the box above ) this fact remains true only because the system on average must be at rest to be weighed ( it must have zero net momentum, which is to say, the measurement is in its center of momentum frame ).

In general, relativistic and rest masses are equal only in systems which have no net momentum and the system center of mass is at rest ; otherwise they may be different.

For compound objects ( made of many smaller objects, some of which may be moving ) and sets of unbound objects ( some of which may also be moving ), only the center of mass of the system is required to be at rest, for the object's relativistic mass to be equal to its rest mass.

This mass is the invariant mass, which is equal to the total relativistic energy of the container ( including the kinetic energy of the gas ) only when it is measured in the center of momentum frame.

In relativistic quantum field theory, a stable bound state of n particles with masses m < sub > 1 </ sub >, ..., m < sub > n </ sub > shows up as a pole in the S-matrix with a center of mass energy which is less than m < sub > 1 </ sub >+...+ m < sub > n </ sub >.
