1. I have published a paper on "Effective field theory of black hole perturbations with timelike scalar profile: formulation" in JCAP with Prof.Shinji Mukohyama (YITP, Kyoto). The effective theory we formulated provides a general framework in the context of scalar-tensor theories for studying dynamics of black hole perturbations, and can be applied to an arbitrary background geometry.2. I have published a papaer on "Generalized Regge-Wheeler equation from Effective Field Theory of black hole perturbations with a timelike scalar profile" in JCAP with Prof.Shinji Mukohyama and Dr.Kazufumi Takahashi (YITP, Kyoto). We used the effetive theory to study dynamics of odd-parity perturbations and obtained the generalized Regge-Wheeler equation which is a central equation to determine the spectrum of quasinormal modes.3. I have written a paper on "Super-horizon resonant magnetogenesis during inflation" with Prof.Misao Sasaki (IPMU, Tokyo) and Dr.Valeri Vardanyan (IPMU, Tokyo). The paper has been accepted in PRD and will be published soon. We proposed a novel mechanism for generating a primordial magnetic field from inflation in order to explain the observed value of magnetic field on the intergalactic scale. We obtained an allowed region of our parameters for which we can explain the observed value of magnetic field, and also avoid the problems such as the strong coupling and the backreaction problems.

1。我发表了一篇有关“带有及时标量概况的黑洞扰动的有效现场理论：与Shinji Mukohyama教授（Yitp，Kyoto）中的JCAP中”的论文。我们制定的有效理论在标量调整理论的背景下提供了一个通用框架，用于研究黑洞扰动的动力学，并可以应用于任意背景几何形状。2。我在JCAP中发表了有关“有效的黑洞扰动的有效现场理论”的爸爸。我们利用冲洗理论来研究奇数扰动的动力学，并获得了广义的regge-wheeler方程，该方程是确定准模式光谱的中心方程。3。我写了一篇关于“通货膨胀期间的超级共振磁化剂”的论文。该论文已在PRD中被接受，并将很快发表。我们提出了一种从通货膨胀产生原始磁场的新型机制，以解释在半乳清尺度上观察到的磁场值。我们获得了参数的允许区域，我们可以解释观察到的磁场值，并避免诸如强耦合和反应问题之类的问题。
