Non-linear aspects of cosmological gravitational waves


Dates: 18 July (Mon., Holiday) - 22 July (Fri) 2022

Venue: Hybrid style with Lecture Hall, Kavli IPMU, Kashiwa, Japan

(sessions will be held on site, with some of them organized in a hybrid style.) 


The discovery of gravitational waves (GWs) by the LIGO and Virgo collaborations has brought GWs as a new and powerful tool for cosmology to study the physics of the universe. The equivalence of energy of matter residing in space-time and the geometry of the space-time tells us that GWs are persistent even in de Sitter space. Further, due to the intrinsic non-linear nature of gravity, cosmological perturbations other than GWs such as observable large-scale structure can source GWs and bring them into existence. Thus, GWs enable us to study both the physics of the very early universe and the evolution of cosmological structure, which will be observed with great accuracy by future surveys such as LSST, Euclid, WFIRST and so on.

The aim of the workshop is, facing the dawn of multi-messenger cosmology led by GWs, to promote stimulating and intensive discussions among the experts on non-linear aspects of GWs and to initiate possible collaborations. We plan to, in addition to the core participants, invite a few key researchers with broad expertise. During the workshop, we plan to organize a few informal seminars a day, and leave ample time for free discussions.
