The Strong Group is now part of a European network set to study nonlinear aspects of Einstein equations. The effort is funded by a Marie Curie RISE project: 101131233 — EinsteinWaves. Other nodes in Europe include Instituto Superior Técnico in Lisbon, Sorbonne in Paris, University of Tubingen, Cordoba in Argentina, Kyoto in Japan and Perimeter Institute in Canada.

This February, five members of the strong group, Conor Dyson, Takuya Katagiri, Rodrigo Panosso Macedo, David Pereniguez, and Thomas Spieksma traveled to the Yukawa Institute for Theoretical Physics (YITP) as part of the European RISE fund program.

The purpose of this travel was to participate in the month long gravity and cosmology workshop at YITP in Kyoto, Japan. This workshop brought together researchers from many different disciplines, including early universe inflation, large scale structure, gravitational wave astronomy and beyond Einstein theories of gravity. This mix of perspectives and ideas centred in the historic Yukawa Institute gave rise to many fruitful conversations which have already resulted in the beginnings of a number of unexpected collaborations.

In additional to the development of exciting new collaborations, five of the members of the strong group, Conor Dyson, Takuya Katagiri, Rodrigo Panosso Macedo, David Pereniguez and Thomas Spieksma also gave talks during the workshop, presenting their recent works on Black Hole Environments in the Strong field regime.
