相对论天文学
Relativistic Astronomy
摘要：
“突破摄星”的目标是在未来向附近的恒星系统发送近光速相机。由于相对论效应，反相对论照相机自然地用作光谱仪、透镜和宽视场照相机。我们证明了这一点，通过模拟的光学波段图像的附近星系M51在休息帧的trans-relativistic相机。我们认为，使用跨相对论照相机观测天体可以使人们以一种特殊的方式研究天体，并对狭义相对论的原理进行独特的检验。我们概述了几个例子，trans-relativistic相机可能对天体物理学做出重要贡献，并建议突破Starshot相机可以在任何方向发射，作为一个独特的天文观测台。
英文摘要：
The "Breakthrough Starshot" aims at sending near-speed-of-light cameras to nearby stellar systems in the future. Due to the relativistic effects, a trans-relativistic camera naturally serves as a spectrograph, a lens, and a wide-field camera. We demonstrate this through a simulation of the optical-band image of the nearby galaxy M51 in the rest frame of the trans-relativistic camera. We suggest that observing celestial objects using a trans-relativistic camera may allow one to study the astronomical objects in a special way, and to perform unique tests on the principles of special relativity. We outline several examples that trans-relativistic cameras may make important contributions to astrophysics and suggest that the Breakthrough Starshot cameras may be launched in any direction to serve as a unique astronomical observatory.
