Large cosmological simulations or observations often result in a significant amount of astronomical data. Scientific conclusions can be drawn from such large data sets by analysing or reducing them with a suitable recipe, i.e. using analysis pipelines or procedural steps. Preserving the associated analysis pipelines and supporting software and computing environments is a must to facilitate their (re-)use. Nowadays, efficient and reproducible analysis of large datasets involves the use of workflow managers that are user-friendly and enable the initiation and monitoring of computational workflow jobs based on containers. REANA is such a reusable and reproducible research data analysis platform. PUNCH4NFDI, on the other hand, provides the infrastructure to meet the need for significant storage and compute resources. The Storage and Compute4PUNCH (S+C4P) infrastructure has several entry points to which REANA provides an easy-to-use interface. In this work, the workflows within the PUNCH have been developed to demonstrate how the S+C4P infrastructure can be used to process astronomical data using REANA. Our demonstration shows how REANA can be utilized for post-processing of simulated data and for miniaturising LoFAR data reduction.
