标题： Constraint on reconstructed f(R) gravity models from gravitational waves

摘要： 引力波（GW）探测由高级LIGO和高级Virgo进行的双中子星旋近事件，为多信使观测开辟了前所未有的道路。 这种引力波的传播速度可以通过比较引力波与中微子或光子到达时间来仔细检验。 它提供了对引力子质量的约束。 f(R)引力理论除了通常的无质量引力子外，还习惯性地具有非零质量的引力子。 之前，我们表明可以从背景演化和物质增长中构建模型无关的f(R)引力理论，其中有一个未确定的参数。 我们表明，这个参数可以由从引力波探测获得的引力子质量限制来约束。 因此，引力波探测为f(R)引力理论的有效性提供了无价的约束。 显示英文摘要

摘要： The gravitational wave (GW) detection of a binary neutron star inspiral made by the Advanced LIGO and Advanced Virgo paves the unprecedented way for multi-messenger observations. The propagation speed of this GW can be scrutinized by comparing the arrival times between GW and neutrinos or photons. It provides the constraint on the mass of the graviton. f(R) gravity theories have the habitual non-zero mass gravitons in addition to usual massless ones. Previously, we show that the model independent f(R) gravity theories can be constructed from the both background evolution and the matter growth with one undetermined parameter. We show that this parameter can be constrained from the graviton mass bound obtained from GW detection. Thus, the GW detection provides the invaluable constraint on the validity of f(R) gravity theories.
