Abstract

Clusters of galaxies are unique laboratories for investigating the dependence of galaxy evolution on their environment. The Herschel Virgo Cluster Survey (HeViCS) mapped the central ∼ 84 - deg 2 region of the Virgo Cluster in five bands between 100 and 500 μ m , which resulted in the first detailed view of cold dust in cluster galaxies. Major limitations of the HeViCS survey were the lack of data, or its limited availability, in the 20 to 80 μ m range, and the quite low sensitivity of the Photodetector Array Camera and Spectrometer instrument, resulting in poor constraints on the warmer dust component. The PRIMAger instrument onboard PRIMA offers the capability to map a large portion of the Virgo Cluster—including regions beyond its virial radius—in hyperspectral and polarimetric bands from 25 to 265 μ m , enabling a direct comparison with the area previously covered by HeViCS. By combining PRIMA and Herschel data with existing multi-wavelength photometry, it becomes possible to explore the connection between stellar and dust properties in a complete sample of cluster galaxies, to investigate environmental effects on the warm dust component within the Virgo Cluster, to map the magnetic field structure of the cold interstellar medium (ISM), to search for dust emission from the intra-cluster medium, and to study the ISM in background galaxies projected behind the cluster.
