标题： Testing the tensor-vector-scalar Theory with the latest cosmological observations

摘要： 张量-矢量-标量（TeVeS）模型被认为是一种可行的引力理论。 它在非相对论弱场极限下产生米尔格罗姆修正牛顿动力学，并且没有幽灵问题。 该模型已经通过各种宇宙学观测进行了检验。 在这里，我们研究新的观测，如由6dF测量的星系速度功率谱和由ACT/SPT测量的动能太阳耶夫-泽尔多维奇效应功率谱，是否能对TeVeS模型施加进一步的限制。 此外，我们通过与普朗克数据对比，对含有惰性中微子的TeVeS宇宙学进行了检验，并发现它被普朗克任务的宇宙微波背景测量排除。 显示英文摘要

摘要： The tensor-vector-scalar (TeVeS) model is considered a viable theory of gravity. It produces the Milgrom's modified Newtonian dynamics in the nonrelativistic weak field limit and is free from ghosts. This model has been tested against various cosmological observations. Here we investigate whether new observations such as the galaxy velocity power spectrum measured by 6dF and the kinetic Sunyaev Zel'dovich effect power spectrum measured by ACT/SPT can put further constraints on the TeVeS model. Furthermore, we perform the test of TeVeS cosmology with a sterile neutrino by confronting to Planck data, and find that it is ruled out by cosmic microwave background measurements from the Planck mission.
