SIMBA Collaboration Meeting

May 1, 2023, 9:00 AM → May 5, 2023, 4:00 PM America/New_York

Ingrid Daubechies Auditorium/2-IDA (162 5th Avenue)

The Simba simulation suite and associated projects such as CAMELS and the 300 Cluster Comparison project have provided novel and state-of-the-art additions to the pantheon of current galaxy formation models. Since its release in 2019, it has been used for a wide range of studies from massive galaxies today to early galaxies seen with JWST, from exploring cold gas in HI and H2 seen at long wavelengths to hot gas in massive halos seen in the X-ray, and from large-scale cosmology to the interstellar medium.

This Simba Team workshop aims to bring together the wide range of astrophysicists working with Simba and affiliated simulations, for both observational and theoretical projects. The goal is to share results and ongoing work with the Simba simulations, coordinate existing projects, and make plans and spur collaborations for future work. We would like to promote the exchange of ideas, tools, and knowledge between subgroups working on different aspects of galaxy formation and cosmology.

If you are interested, please register for the workshop. There is no workshop registration fee and breakfast/lunch/coffee breaks are generously provided by the Flatiron Institute. Other travel costs are to be borne by the participants. The workshop will begin the morning of Monday May 1, 2023 and end at lunchtime on Thursday May 4. Workshop participants are welcome to stay the rest of the week to explore more collaborations with other attendees and/or CCA folks.
