论文摘要
我们提出了一种相对论的引力理论，导致了经过修改的牛顿动力学，该范式解释了观察到的通用银河加速度量表和相关现象学。我们讨论了导致其构建的现象学要求，并证明了其与线性宇宙学量表上观察到的宇宙微波背景和物质功率谱。我们表明，它的作用扩展到二阶的，没有鬼魂的不稳定性，并讨论了它在更基本的理论中的可能嵌入。
We propose a relativistic gravitational theory leading to modified Newtonian dynamics, a paradigm that explains the observed universal galactic acceleration scale and related phenomenology. We discuss phenomenological requirements leading to its construction and demonstrate its agreement with the observed cosmic microwave background and matter power spectra on linear cosmological scales. We show that its action expanded to second order is free of ghost instabilities and discuss its possible embedding in a more fundamental theory.
