报告提纲

• GWs induced by non-Gaussian scalar perturbations: K³-solpe, multiple peaks, and a cutoff.

• If PBHs can sever as all the DM, induced GWs must be detectable by LISA, no matter how small A_R or f_NL is.

• Conversely if LISA can not detect the induced GWs, we can put an indepentent constraint on the PBH abundances on mass range 10¹⁹g to 10²²g where no current experiment can experiment can explore.

个人简介

Shi Pi, Project Researcher in Kavli IPMU, The University of Tokyo，his main research interests focus on the early cosmology, especially the generation and evolution of cosmological perturbations. Originating from the quantum fluctuations on very small scales, cosmological perturbations can be stretched to all the scales and then seed the macroscopic phenomena like cosmic microwave background, large scale structure, primordial black holes, and stochastic gravitational waves. I am trying to comprehend how the largest and the smallest scales of our universe are connected by the Nature. His Research direction: Astronomy (Astrophysics); Cosmology and Statistics; Inflation and Early Universe; Observational Cosmology.

会议简介

2019年度华中师大－中国科大宇宙学青年学术研讨会于2019年4月26日-4月29日在武汉举办。为了促进相关领域青年学者的学术交流，特组织召开此次会议。本次会议以口头报告及墙报的形式研讨交流引力波时代下引力与宇宙学的相关课题，充分研讨交叉领域的研究现状、重要问题和未来发展方向，展示最新研究成果和进展，以及探讨如何推进我国青年学者在引力与宇宙学领域的进一步发展和科学合作。
