Quasars below a certain redshift will not show the Gunn-Peterson trough ( though they may show the Lyman-alpha forest ), while quasars emitting light prior to reionization will feature a Gunn-Peterson trough.

Quasars also show ' forbidden ' spectral emission lines which were previously only seen in hot gaseous nebulae of low density, which would be too diffuse to both generate the observed power and fit within a deep gravitational well.

Quasars also happen to have relatively uniform spectral features, regardless of position in sky or distance from Earth.

( Quasars are also associated with an accreting compact object, but are thought to be merely a particular variety of AGN.

Quasars are believed to be powered by accretion of material into supermassive black holes in the nuclei of distant galaxies, making these luminous versions of the general class of objects known as active galaxies.

Quasars ( short for " quasi-stellar radio source ") were one of the first point-like radio sources to be discovered.

* Quasars have been photographed since the late 19th centuries although they were not known to be unusual objects until the 1960s.

Celestial objects like Quasars, super dense objects that lie far from Earth, emit electromagnetic waves in its full spectrum including radio waves.

* Quasars ( objects the size of the solar system and as luminous as a hundred modern galaxies, so distant that they date from the early years of the universe );

* Quasars ( objects the size of the solar system and as luminous as a hundred modern galaxies, so distant that they date from the early years of the universe );

Quasars are extremely luminous and were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, that were point-like, similar to stars, rather than extended sources similar to galaxies.

Bell and D. McDiarmid, reported: " Six Peaks Visible in the Redshift Distribution of 46, 400 SDSS Quasars Agree with the Preferred Redshifts Predicted by the Decreasing Intrinsic Redshift Model ".

Quasars are a good candidate source because they are highly efficient at converting mass to energy, and emit a great deal of light above the threshold for ionizing hydrogen.

Quasars show a very high redshift, which is an effect of the expansion of the universe between the quasar and the Earth.

Due to the high frequency used, the chances finding gravitational lenses increases as the relative number of compact core objects ( e. g. Quasars ) are higher ( Sadler et al.

Quasars were originally ' quasi-stellar ' in optical images, and so had optical luminosities that were greater than that of their host galaxy.

* Arp, Halton C., Quasars, Redshifts and Controversies.

Quasars are not radio stars.

Quasars release an extraordinary amount of energy, meaning they are among the brightest objects in the universe.

Quasars ' extreme red shift led us to conclude that they are distant active galactic nuclei.

Recognizing that the Rule of Law is `` a dynamic concept which should be employed not only to safeguard the civil and political rights of the individual in a free society '', the Congress asserted that it also included the responsibility `` to establish social, economic, educational and cultural conditions under which his legitimate aspirations and dignity may be realized ''.

The answers derived by these means may determine not only the temporal organization of the dance but also its spatial design, special slips designating the location on the stage where the movement is to be performed.

Yet, after Rousseau had given the social contract a new twist with his notion of the General Will, the same philosophy, it may be said, became the idea source of the French Revolution also.

That, however, may also bring the police, if the thinking does not meet with social approval.

He and also Mr. Cowley and Mr. Warren have fallen to the temptation which besets many of us to read into our authors -- Nathaniel Hawthorne, for example, and Herman Melville -- protests against modernism, material progress, and science which are genuine protests of our own but may not have been theirs.

He may also consider ideas.

We may also recognize cases in which the poets have influenced the philosophers and even indirectly the scientists.

We may further grant to those of her ( Poetry's ) defenders who are lovers of poetry and yet not poets, the permission to speak in prose on her behalf: let them show not only that she is pleasant but also useful to States and to human life, and we will listen in a kindly spirit ; ;

A slow and painful trend toward unification has taken hold, a trend which may at any time be arrested and reversed but which may also lead to a binding federation of Europe.

The defect of these proposals is in their attempt to outrun history and their assumption that because something may be desirable it is also possible.

Perhaps, as Mr. Freeman says, American agriculture may stop the Communists, but it is also swindling the American taxpayer.

and also that they may have 5 legislative days in which to extend their remarks.

An outdoor, aboveground fallout shelter also may be built with concrete blocks.

No corporation engaged in commerce shall acquire, directly or indirectly, the whole or any part of the stock or other share capital of another corporation engaged also in commerce, where the effect of such acquisition may be to substantially lessen competition between the corporation whose stock is so acquired and the corporation making the acquisition, or to restrain such commerce in any section or community, or tend to create a monopoly of any line of commerce.

The return for a decedent may also serve as a claim for refund of an overpayment of tax.

If your child is under 19 or is a student you may also claim an exemption for him if he qualifies as your dependent, even though he earns $600 or more.

Since you contributed more than half of his support, you may also claim an exemption for him on your return.

While this may well be true in general, I believe it is also important to keep in mind that some recent developments suggest that over the next year or so military electronics may be one of the most strongly growing areas in an economy which is not expanding rapidly in other directions.

Outboard motors, insurance, and boat repairs may also be financed in the same way as boats.

Boatyards which also provide some of the above facilities may rightfully be called marinas.

It may be true that pool lighting dramatizes an evening scene, but lights also attract all the insect life for miles around.

A site may also be attractive just through the beauty of its trees and shrubs.

It may also work in one other way -- by licensing its system patents and supplying the meters, letting the oil company or even the builder install the facilities.
