HST F160W image with the distribution of the 28 cluster members with spectroscopic redshifts in the center of the XMM2215 cluster. The 500 × 500 kpc² area (at z ∼ 1.46) covered by MUSE is shown by the large black square. Only the 28 galaxies are shown that lie inside a circular area (indicated by the large black circle) with a radius of 250 kpc around the cluster X-ray center (tiny open black circle). Fourteen galaxies with z < 1.457 (and 14 at z > 1.457) are highlighted in blue (and red); SF galaxies by open circles, three AGN by blue and red rhombuses, and passive galaxies by blue and red squares. The IDs follow the notation that was used by M19. The 14 galaxies with ALMA molecular gas measurements are in addition denoted by black hexagons. The rough positions and form of the three blobs of diffuse warm ionized [OII] gas are shown by blue and red ellipses (the color depends on the redshift). The smaller black circle with a diameter of ∼200 kpc around the cluster center is populated only by passive galaxies, an AGN, and the ionized gas blobs. The galaxies with ALMA molecular gas detections (hexagons) all lie outside this area.
