This virtual workshop gathers a group of international experts on gravitational-wave primordial cosmology. It will take place on zoom, over three half-days on May 17th-19th, from 2pm to 6.30pm CEST.
The main goal of the workshop is to critically review recent progress about the potential of gravitational waves to probe inflation on small scales, but related aspects like preheating, primordial black holes, phase transitions and the thermal history of the universe will also be discussed. A particular focus will be given to the observability of the various properties of the stochastic gravitational wave background, including its spectral shape and polarisation, and their implications for the inflationary mechanism and field content. Cross-correlations with other observables will also be discussed, together with methods of data analysis and prospect for detection.
But this workshop will not be limited to a review of recent progress. It also aims at collectively identifying important open questions and assessing the potential of discovery of gravitational wave astronomy for primordial cosmology. For this, in addition to invited presentations, lasting 30 minutes each, time will be left for informal discussions, and the workshop will end with a summary of the important issues to address in this field.
There is no registration fee, but registration through indico is compulsory.
Organisers: Sébastien Renaux-Petel, Jacopo Fumagalli, Sebastian Garcia-Saenz, Sadra Jazayeri, Lucas Pinol, Lukas Witkowski
