THE NEAR, THE FAR, AND THE IN-BETWEEN: SYNERGY BETWEEN LOW AND HIGH REDSHIFT GALAXY EVOLUTION STUDIES IN THE ERA OF JWST AND EUCLID

NOORDWIJK, THE NETHERLANDS

Scientific Rationale:
In the past decades, the field of galaxy evolution has witnessed a large amount of fruitful study, centered both on detailed investigation of, usually low redshift, individual objects/small samples, as well as on large galaxy surveys (e.g. SDSS, 2MASS, COSMOS, CANDELS, GAMA), and the corresponding simulations. However, the large differences in attainable resolution have, to a degree, posed a barrier in bringing together the individual findings, both between individual studies and surveys as well as between surveys at different redshifts, and creating a homogeneous picture of the processes determining the fate of a galaxy and their evolution.

This has recently begun to change with the advent of medium depth spectroscopic and imaging surveys (e.g. GAMA) and large IFU galaxy surveys (KMOS^3d, MANGA, SAMI), but the coming generation of facilities, instruments and surveys will open a new realm of possibilities. E.g. Euclid (in concert with ground based facilities such as, e.g. LSST and ALMA) will enable the study of large volume wide area samples of galaxies comparable to current low redshift surveys at z~1, while JWST will allow analogues of the highest redshift galaxies to be studied over large redshift baselines and will probe the first galaxies to appear in the Universe. In general, we will be entering an era in which detailed physical information for large galaxy samples over a significant fraction of the age of the universe will be available, thus changing the empirical basis for the study of galaxy evolution, and creating the need to combine best practices and experience, and expertise from both large, statistical and detailed, individual studies of galaxies.

In light of these developments, this meeting focuses on bringing together experts working on these key questions of galaxy evolution

• star formation in galaxies
• the baryon cycle
• properties of the circum-galactic medium (CGM)
• properties of the inter-galactic medium (IGM)
• galaxy mergers
• Large-scale structure/the cosmic web

over a range of redshifts to assess and assemble a current picture of galaxy evolution, identify open questions and possible synergies, and possibilities of collaboration, in particular in light of the upcoming facilities and surveys, and to identify key avenues of future enquiry.

The aim of the meeting is to bring together experts from the low and high redshift community working on the different aspects outlined above. In addition to review and contributed talks, we plan to include special sessions devoted to discuss about current methods and how to best exploit future observing facilities in that framework.

Attendance will be limited to 100 participants. We warmly invite scientists from all levels (PhD, PostDoc, Permanent staff) and all backgrounds to attend.
