MeerKAT 21-cm H I imaging of Abell 2626 and beyond

Context. The morphology-density relation manifests the environmental dependence of formation and evolution galaxies as they continuously migrate through cosmic web to ever denser environments. As gas-rich traverse outskirts inner regions galaxy clusters, experience sudden radical changes in their gas content star activity. Aims. goal this work is gain an H I perspective on depletion mechanisms acting groups that are being accreted by a moderately massive cluster. We aim study relative importance efficiency processes such ram-pressure stripping tidal interactions well dependency local global environment cluster core its surroundings. Methods. have conducted blind radio continuum spectral line imaging survey with MeerKAT telescope 2° × area centred Abell 2626. used CARAcal pipeline reduce data, SoFiA detect sources within data cube, GIPSY construct spatially resolved information morphologies kinematics detected galaxies. Results. 219 optical counterparts entire surveyed volume. present properties each catalogue atlas page for galaxy, including column-density maps, velocity fields, position-velocity diagrams, profiles. These will also be case studies identified ‘jellyfish’ population means morphological classification direct detections using stacking technique.
