The Fermi Space Telescope is so sensitive to these gamma ray bursts that it doesn't even need to be positioned right over a thunderstorm to detect the TGFs.
费米太空望远镜对这些伽马射线脉冲很灵敏,以至于它甚至不需要调整位置对准雷暴的正上方,就能来探测TGF信号。
The Fermi Space Telescope found hints in 2009 of the telltale pattern associated with positrons in terrestrial gamma rays stemming from lightning storms.
费米太空望远镜在2009年就曾发现这一与正电子有关的特征现象的线索,地点正是在源于雷暴的地表伽马射线中。
The Hubble Space Telescope captured this image of a gamma ray explosion on January 23, 1999.
哈勃望远镜捕捉到的这张照片显示的是1999年1月23日伽马射线爆炸的景象。
But how can terrestrial gamma rays reach Fermi's orbit in space?
但地表伽马射线如何能到达太空中安放费米镜的卫星呢?
Astronomers keep discovering new noisemakers in space: colliding black holes, glitching pulsars, gamma ray bursts.
天文学家仍然致力于寻找太空中新的声源:黑洞碰撞,脉冲星干扰,伽马射线爆破。
PSR J0357 was originally discovered by the Fermi Gamma Ray Space Telescope in 2009.
PS r J 0357最初是通过费米·伽玛射线太空望远镜(Fermi Gamma Ray Space Telescope)于2009年发现的。
The awesome power of those quakes can blast gamma rays into space, leading scientists to suspect that the stars' crusts must be very hard to break.
那些震动的强大力量到将会朝太空发出伽马射线释,让科学家们怀疑这些星球的地壳一定很难打破。
I often work in gamma 1.0 space actually, but this time I decided to work in gamma 2.2 using Linear work Flow.
在平时工作中我实际上都是使用伽马1.0,但是这一次我决定使用伽马2.2的线性工作流程。
But one of the strangest things in space is the mystery of Gamma Ray Bursts.
但是宇宙中最奇怪的东西之一是伽玛射线爆发之谜。
The Hubble Space Telescope captured this image of a gamma ray explosion on January 23, 1999. At the time it was the most powerful explosion ever recorded.
哈勃望远镜捕捉到的这张照片显示的是1999年1月23日伽马射线爆炸的景象。这是当时人们纪录过的最大规模的一次伽马射线爆炸。
We use EGS4 code to simulate the electron-gamma shower of high-energy electrons in a medium, optimize target thickness, and analyze positron distributions in phase space.
首先使用程序包EGS4 ,对高能电子在介质中的电磁级联过程进行了模拟,优化了靶厚度,讨论了影响打靶产额的因素。
