We explore the internal dynamics of Abell 2254, which has been shown to host a very clumpy and irregular radio halo. Our analysis is mainly based on redshift data for 128 galaxies acquired at the Telescopio Nazionale Galileo. We combined galaxy velocities and positions to select 110 cluster galaxies and analyze its internal dynamics. We also used new (g', r', i') photometric data acquired at the Isaac Newton Telescope, and (V, i') photometric data available in the Subaru Archive. X-ray data from the XMM-Newton Science Archive were analyzed to study the hot gas component. Description: Multi-object spectroscopic observations of A2254 were carried out at the TNG telescope in May and October 2009 and in March 2010. Our photometric observations were carried out with the Wide Field Camera (WFC), mounted at the prime focus of the 2.5m INT telescope. We observed A2254 in g', r', and i' SDSS filters in photometric conditions and a seeing of ∼1.6". Subaru Suprime-Cam data were retrieved from the SMOKA archive ( File Summary:
