kaia•hö•kü: Towards Understanding the origin of the Complexity and Diversity

Science Sessions - Galaxy Formation

The field of galaxy formation and evolution covers a wide range of astrophysical scales; from the dust grain formation to the cosmic large-scale structure. Different astrophysical processes are operating on different scales, driving the complex and diverse nature of galaxies.

In order to understand how galaxies form and evolve, we thus need to look at all aspects across cosmic time. In this parallel session, we invite contributions from the broader galaxy community, both from observational and theoretical perspectives, and covering the full electromagnetic spectrum, to tackle this complex problem. The Subaru Telescope has played a major role in understanding galaxies across cosmic history with its unique wide-field capabilities, and as part of the Subaru 20th anniversary conference, we facilitate discussions on the future prospects of Subaru and its synergy with upcoming ground and space-based facilities.
