CL2025: Entering a Golden Age of Galaxy Cluster Studies (Abstract submission by 7/7)
CL2025: Entering a Golden Age of Galaxy Cluster Studies The First East Asian Workshop on Galaxy Clusters
September 23-26, 2025 Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA), Taipei, Taiwan

*** Scientific rationale
With the rich datasets delivered by ongoing and upcoming large-scale imaging and spectroscopic surveys such as Subaru Hyper Suprime-Cam (HSC) survey, Dark Energy Survey, Kilo-Degree Survey, Legacy Survey of Space and Time (LSST), Euclid, Roman, Dark Energy Spectroscopic Instrument (DESI), Subaru Prime Focus Spectrograph (PFS), eROSITA, South Pole Telescope, Atacama Cosmology Telescope/Simons Observatory, CMB-S4, we are entering a golden age for studying all aspects of galaxy clusters – from cosmological constraints, rise and fall of star formation activities of cluster galaxies, physics of intracluster medium, role of cosmic filaments in cluster formation, to properties of dark matter, only to name a few.
The primary purpose of this new series of workshops is to gather researchers from all over the world – with an emphasis on East Asian regions – to share the latest findings, discuss novel approaches, and form new collaborations. The first installment will be held at the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA) in Taipei, Taiwan, on 9/23-26/2025. During the 4-day workshop, we will have high-quality invited and contributed talks, poster presentations, 3 hour-long discussion sessions, and a half-day free time for further interactions. All the talks in the workshop will be in person, although we might be able to broadcast the talks in real time.
The topics to be covered include (but not limited to):
- Star formation and AGN activities in clusters and groups
- Gas inflows and outflows and feedback
- Roles of cosmic filaments and groups on properties of gas and galaxies
- Quenching of galaxies and their dependencies on mass and environment
- Mass assembly of clusters and the formation of BCGs and ICL
- Circum-galactic medium of galaxies in clusters/groups
- Hot side of clusters
- Custer mass estimates and scaling relations
- Dark matter properties
- Status of ongoing surveys and prospects of future projects
We plan to hold the workshop series in Taiwan, Japan, and Korea every 1-2 years.
