我們計算了由引力波輻射引起雙星系統的角動量損失的演化模型，發現雙星系統還是經歷循環演化，不過循環的周期變短，且雙星系統的每一個循環處在半接狀態的時間與處在相接狀態的時間之比變小。Instead of a single wave swooping around the galaxy, multiple waves can travel inward and outward
除了單一波動猛撲星系外，也有多重波動向內外擴散。Because the jets lie close to m106 ' s disk, the cocoon generates shock waves and heat the gas in the disk to millions of degrees, causing it to radiate brightly in x - rays and other wavelengths
由於噴流靠近m106的星系盤，繭狀結構會產生激波，將盤中的氣體加熱的幾百萬度，使其在x射線及其他波段上發出明亮的輻射。Direct hits between stars are extremely rare when galaxies collide, but huge gas clouds can crash into each other at high speeds, creating shock waves that heat the clouds and the surrounding gas to millions of degrees
當星系相撞時，恆星之間的對撞非常少，但巨大的氣體雲團會以高速互相沖擊，產生激波，並將雲團和周圍的氣體加熱到幾百萬度。In the closeup view on the lower left, also color coded by x - ray energies, the point sources have been taken out to emphasize the hot gas clouds in the central regions of the antennae
在左下的放大圖中（仍按x射線波段的著色法表示） ，點源已被扣除，這樣就可以突出觸角星系中心區域的熱氣體雲。Tegmark is an expert in analyzing the cosmic microwave background and galaxy clustering
鐵馬克是分析宇宙微波背景輻射與星系團的專家。For examples, observation of the gravitational lens phenomenon and the scattering phenomenon produced by microwave background radiation and hot plasmas from galaxies clusters
，例如利用引力透鏡現象及微波背景輻射與星系團的熱等離子體造成的散射現象等等。With the advancement of detector technology, astronomers now can exploit observations in different wavelengths to study astronomical objects. for example, the ultraviolet image of m81 in picture can be used to locate the very hot o type and b type stars in that galaxy
隨著探測器技術的日益改進，天文學家已可利用不同波段來觀測宇宙，例如利用m81的紫外線照片圖b尋找星系內的熾熱o型和b型恆星。The corotation circle acts as an interface that can either reflect or transmit these waves, allowing them to gain energy at the expense of the global rotational kinetic energy of the galaxy
共同旋轉圈的作用，像個可以反射或透射這些波的介面，讓它們轉換星系整體的轉動動能為自身的能量。Images from three of nasa ' s great observatories were combined to create this spectacular, multiwavelength view of the starburst galaxy m82
結合來自nasa的3架大天文臺的照片，得出了這張壯觀的星爆星系m82多波段圖象。They focus on submillimeter galaxies, so called because astronomers see them in light with a wavelength a bit shorter than one millimeter
他們鎖定的是次毫米星系，之所以這樣稱呼，是因為天文學家是在比毫米稍短的波長中看到它們的。In visible ( shown in gold ) and infrared ( red ) light, two prominent arms emanate from the bright nucleus and spiral outward
在可見光（以金黃色表示）和紅外（以紅色表示）波段，兩條突出的旋臂從星系核區伸出，並螺旋向外延展。By analyzing data from xmm - newton, spitzer, and chandra, scientists have confirmed earlier suspicions that the ghostly arms represent regions of gas that are being violently heated by shock waves
在可見光（以金黃色表示）和紅外（以紅色表示）波段，兩條突出的旋臂從星系核區伸出，並螺旋向外延展。When stars ' ellipses rotate at widely different speeds, the galaxy has no wave structure
當恆星畫出的橢圓彼此間繞轉速率差異甚大時，星系不會出現波動結構。And astronomers, in fact, have seen evidence of spiral - wave patterns in accretion disks in some binary systems
事實上天文學家已在一些雙星系統的吸積盤中，看見螺旋波圖樣的證據。Another possibility is that large - scale spiral waves in the disk, similar to the spiral arms observed in galaxies, hasten the inflow of matter
另一個可能性是，類似星系旋臂的大尺度螺旋波，加劇了物質的向內流動。First, the structure of the second generation ctdrs isl was discussed in this paper, the characteristic of coverage in the second generation ctdrs by the characteristic of orbit and the simulation model of isl was analyzed then the effect of the isl establishing process analyzed. second, the discussing and analyzing focus on the characteristic of signal during the establishing isl process, establishing the orbit model, the technology of doppler frequency shift capturing and tracking sequence and the effect of background noise, then the theory analyzing the parameters we have just mentioned, and this will support the reference for the implement of project. the simulation and test of the isl of ctdrs and analyzing from theoretical basis to implement of simulation were mainly focused in this paper
其中討論了二代中繼星捕獲跟蹤系統星間鏈路的模擬方案的組成結構，利用軌道特性對二代中繼衛星系統的覆蓋特性進行分析，搭建了星間鏈路的模擬模型，其中包括中繼衛星和用戶衛星在內的軌道模型、星間鏈路模型、用戶星信號調制模型等，並對星間鏈路建立過程的影響進行分析;重點針對星間鏈路建立過程的信號特性，軌道模塊的建立、多普勒頻移技術、背景噪聲影響、載波的捕獲與跟蹤技術等進行了實際參數的設計與理論分析。This image combines data from four different observatories : the chandra x - ray observatory ( purple ) ; the galaxy evolution explorer satellite ( ultraviolet / blue ) ; the hubble space telescope ( visible / green ) ; the spitzer space telescope ( infrared / red )
這張照片是使用4架軌道天文臺的數據合成的：錢德拉x射線天文臺（紫） 、星系演化探測器（紫外波段，藍色） 、哈勃太空望遠鏡（可見光波段，綠色）以及斯必澤太空望遠鏡（紅外波段，紅色） 。分享友人
