Abstract : with the theory of vacuum phase - transition and the special theory of relativity , and adding two simple hypotheses that are not contradictory to the theories now available , the paper deduces a kind of energy fomula that gives a probable interpretation of some quasars “ energy mechanism that far exeeds the energy of nuclear 文摘:利用真空相變理論和狹義相對論,加上兩個與現有理論不相矛盾的簡單假設,導出了一種能量計算式,對某些類星體遠比核能強大的能源機制提出了一種可能的解釋 |

According to nasa , ever since quasars were first discovered in 1963 “ astronomers have been trying to crack the mystery of how these compact dynamos of light and other radiation , which lie at the outer reaches of the universe , produce so much energy 自從恒星狀球體在1963年被首次發現,天文學家就開始試圖弄清這些位于宇宙外部區域的類星體是如何持續產生強大、耀眼的光亮的。 |

Glast telescope : on october 7 , the gamma - ray large area space telescope will launch into orbit and begin to observe our universe ' s most fascinating phenomena , including black holes , quasars and neutron stars 格拉斯特天文望遠鏡: 10月7日,伽瑪射線大區域太空望遠鏡( glast )將發射升空,用以觀察宇宙中最迷人的現象,包括黑洞、類星體和中子星。 |
|
Indeed the introduction of this theory in the 1970s removed a major objection to the belief that quasars were distant galaxies - namely , that no physical mechanism could generate that much energy 的確這個理論的在1970年代內引進脫離了一主要缺陷來相信類星體是遙遠的星系-即,沒有物理機制可以產生那麼多能量。 |
|
Thus , we conclude that they radiate enormous amount of energy , even larger than those active galaxies nearby . quasar is probably also the supermassive black hole at the center of a young galaxy 我們可以肯定它們所發出的能量非常驚人,甚至比附近的活動星系更厲害,它們可能是中心有特大質量黑洞的年青星系。 |
|
The latest chandra results suggest that such collisions may cause extreme black hole and galaxy growth in the early universe , setting the stage for the birth of quasars 天文學家相信,星系的中心存在有一個質量很高的超級黑洞,而現今的星系,主要是由古代時星系間的碰撞而演化到今天的模樣。 |
|
In an age of increasing specialization , she maintains a broad range of interests , from interstellar gas to quasars to dark matter , spanning both observation and theory 在這個各領域越來越講究專精的年代,她仍保持廣泛的研究興趣,從星際氣體到類星體到暗物質,并且橫跨了觀測與理論的研究。 |
|
Also , vsop cannot frequently change observing object , hence it cannot supply more observations to many quasars , which are required for geodesy and geodynamics Vsop還不適合于頻繁改變觀測對象,所以無法提供針對多個射電源的觀測量,而這正是大地測量和地球動力學所需要的。 |
|
“ we can also try to determine whether the same physical laws applied in the distant past because we see quasars as they were long ago , “ he said “同時我們可以確認相同的物理定律是否適用于遠古時期,因為我們所看見的是很久以前的類星體, ”他說。 |
|
Candidates for more massive black holes were first provided by the active galactic nuclei and quasars , discovered by radioastronomers in the 1960s 活躍的銀河核和類星體首先提供了更多質量龐大的黑洞候選者,在1960年無線天文學家發現了它們。 |
|
We needed high - precision laboratory measurements against which to compare the quasar spectra , so we persuaded experimenters to undertake them 我們需要有實驗室中的高精密量測,以比較類星體的光譜,因此我們勸說了實驗學家從事此項實驗。 |
|
Ironically , scientists used to know more about the spectra of quasars billions of light - years away than about the spectra of samples here on earth 諷刺的是,相較于地球上的光譜樣本,科學家反而更了解位在數十億光年遠處的類星體光譜。 |
|
The quasar image scooted 1 , 300 microarcseconds across the sky ? with a 50 - microarcsecond skew , just as expected from relativistic effects 類星體在天上的影像掃過了1300微弧秒,再加上50微弧秒的歪曲,正和相對論所預期的效應一樣。 |
|
The most powerful such object is a quasar , which emits a huge amount of radio , infrared , ultraviolet , x - ray , and gamma - ray energy 這種物體多數是一個發射巨大能量(包括射電、紅外線、紫外線、 x射線和伽瑪射線在內)的類星體。 |
|
To do this , it will examine what happens to the beams coming from faint , distant quasars as they pass through the cosmic web 因此,該儀器需要觀測昏暗遙遠的類星體所發出的光線在穿過“宇宙網”時所發生的情況。 |
|
Last september they put their plan into action when jupiter passed close to the line of sight between earth and a quasar 去年9月,當木星接近一條從某個類星體射向地球的光線路徑時,他們便開始將計畫付諸行動。 |
|
The name comes from the fact that the first quasars identified emit mostly radio energy and look much like stars 這個名字實際上來自首個被確認的類星體,它所發射的絕大部分是射電能并且看上去很像恒星。 |
|
The project is now approaching the halfway point in its goal of measuring one million galaxy and quasar redshifts 這個計畫的目標是量取100萬個星系與類星體的紅移,現在已將達成目標的一半。 |
|
Quasars are no larger than our solar system but outshine galaxies of hundreds of billions of stars 這些恒星狀球體并不比我們的太陽系大,但是它卻比擁有數十億星體的星系還要亮很多。 |
