The exploration of extradimensions in terms of a variety of cosmophysical phenomena caused by axionic moduli

为了打开一个通往终极理论的新的观测/实验窗口，我们从宇宙物理唯象学和超弦/超引力两个方面研究了轴子，发表了200多篇论文。主要成果有：用数值模拟证明了旋转黑洞产生的轴子玻色新星粒子，并通过引力波实验发现了它的可观性，导出了解决高能伽马射线观测和红外背景观测之间冲突的轴子的参数范围，评估了重模衰变产生的轴子对宇宙微波背景的影响，并在此基础上导出了额外维度压缩的约束条件，从轴离子等温扰动和拓扑缺陷的宇宙学影响导出了对基本粒子模型的约束。

In order to open up a new observational/experimental window to the ultimate theory, we have studied axions from both the cosmophysics phenomenology aspect and the superstring/supergravity aspect and have published more than 200 papers. The main achievements are demonstarations of the axion bose nova phenemenon caused by a rotating black hole by numerical simulations and the discovery of its observability by gravitational wave experiments, derivation of a parameter range for axion to resolve the conflict between the high energy gamma-ray observations and the infrared background observation, evaluations of the influences of axions produced by the decay of heavy moduli on cosmic microwave background and derivation of constraints on the compactification of extra-dimensions on the basis of this estimation, derivation of constraints on elementary particle models from cosmological influences of axionic isocurvature perturbations and topological defects.
