MOND标度下的冷暗物质
Cold Dark Matter with MOND Scaling
摘要:
我们提供了一个全息的双重描述Milgrom的缩放与银河系的旋转曲线。我们的论点是基于最近熵的牛顿运动定律的重新解释。我们提出了一个二元性之间的冷暗物质和修改的牛顿动力学(MOND)。我们介绍了MONDian暗物质的概念,并讨论了它的一些唯象意义。在星系团和宇宙学的尺度上,MONDian的暗物质会表现为冷的暗物质,但在银河系尺度上,MONDian的暗物质会表现为MOND。
英文摘要:
We provide a holographic dual description of Milgrom's scaling associated with galactic rotation curves. Our argument is based on the recent entropic reinterpretation of Newton's laws of motion. We propose a duality between cold dark matter and modified Newtonian dynamics (MOND). We introduce the concept of MONDian dark matter, and discuss some of its phenomenological implications. At cluster as well as cosmological scales, the MONDian dark matter would behave as cold dark matter, but at the galactic scale, the MONDian dark matter would act as MOND.
