非相对论扩展引力及其在不同天体物理尺度上的应用
Non-relativistic Extended Gravity and its applications across different astrophysical scales
摘要:
使用量纲分析技术,我们提出了一个扩展的牛顿引力理论的假设下,Milgrom的加速度常数是一个基本量的性质。引力收敛于牛顿引力,并在两个不同的质量和长度制度的MOND类描述。它表明,修改的力部门(而不是在动力学的MOND)是更方便,可以重现和预测不同的现象通常归因于暗物质在非相对论水平。
英文摘要:
Using dimensional analysis techniques we present an extension of Newton's gravitational theory built under the assumption that Milgrom's acceleration constant is a fundamental quantity of nature. The gravitational force converges to Newton's gravity and to a MOND-like description in two different mass and length regimes. It is shown that a modification on the force sector (and not in the dynamical one as MOND does) is more convenient and can reproduce and predict different phenomena usually ascribed to dark matter at the non-relativistic level.
