The MGCLS–H I database provides free, open access to H I galaxy cluster data and multi-wavelength preview figures from the MeerKAT Galaxy Cluster Legacy Survey.

Our cloud-hosted front-end is supported by SARAO, the MGCLS team, RATT, Rhodes University, AWS and the SoFiA-2 community — you only use bandwidth and compute when you browse or download data products.
