论文摘要
采用了一种新方法来推导Schwarzschild黑洞的红移和阴影，该黑洞在DE Sitter中自由移动，如一个共同移动的远程观察者所记录的。该方法是男子气概的代数，重点是在de sitter等轴测图下的转换，将适当的共同移动框架与观察者的框架相关联。因此，人们提取了具有奇特速度的黑洞的红移和阴影的一般表达，但它们的表达太扩展了，以至于在这里写下。因此，仅在计算机\ cite {comp}上以代数代码给出完整结果的同时，仅显示一些特定情况和直观的扩展。
A new method is applied for deriving the redshift and shadow of a Schwarzschild black hole moving freely in the de Sitter expanding universe as recorded by a co-moving remote observer. This method is manly algebraic focusing on the transformation of the conserved quantities under the de Sitter isometry relating the black hole proper co-moving frame to observer's one. Hereby one extracts the general expressions of the redshifts and shadows of the black holes having peculiar velocities but their expressions are too extended to be written down here. Therefore, only some particular cases and intuitive expansions are presented while the complete results are given in an algebraic code on computer \cite{Comp}.
