R. Marleau et al.As part of the Euclid ERO series of papers, we have used Euclid imaging of the Perseus cluster to demonstrate the capabilities of the telescope for dwarf galaxy science. The depth, spatial resolution, and FoV have allowed us to detect and characterize 1100 dwarf galaxy candidates in a 0.7deg^2^ field, slightly offset from the BCG, NGC1275. We visually classified their morphologies, extracted their photometric and structural properties, quantified their GC populations, and mapped their spatial distribution across the cluster. table A.1: Visual properties of the sample of dwarf galaxies candidates. The column definitions are as follows: unique identifier (ID), right ascension in degree (RA), declination in degree (Dec), morphology (dE, dI), GC-rich flag (dwarfs with N_GC > 2 GCs),1455 presence of nucleus flag (Nucleated), disturbed flag (Disturbed). table A.2: Photometric and structural properties of the dwarf galaxy candidates. table A.3: Aperture magnitudes and extinction corrections (EC) in the Euclid Y_E, J_E and H_E bands for each dwarf galaxy candidate. table B.1: Visual properties of the galaxies from our initial list of sources with a score below the threshold of 0.7 (corresponding to 5/7 classifiers). The column definitions are as follows: unique identifier (ID), right ascension in degree (RA), declination in degree (Dec), morphology (dE, dI), GC-rich flag (dwarfs with N_GC > 2 GCs), presence of nucleus flag (Nucleated), disturbed flag (Disturbed)."This research has made use of the VizieR catalogue access tool, CDS, Strasbourg, France (DOI : 10.26093/cds/vizier). The original description of the VizieR service was published in 2000, A&AS 143, 23"We make use of the unprecedented depth, spatial resolution, and field of view of the Euclid Early Release Observations (EROs) of the Perseus galaxy cluster to detect and characterise the dwarf galaxy population in this massive system. Using a dedicated annotation tool, the Euclid high resolution VIS and combined VIS+NIR colour images were visually inspected and dwarf galaxy candidates were identified. Their morphologies, the presence of nuclei, and their globular cluster (GC) richness were visually assessed, complementing an automatic detection of the GC candidates. Structural and photometric parameters, including Euclid filter colours, were extracted from 2-dimensional fitting. Based on this analysis, a total of 1100 dwarf candidates were found across the image, with 606 appearing to be new identifications. The majority (96%) are classified as dwarf ellipticals, 53% are nucleated, 26% are GC-rich, and 6% show disturbed morphologies. A relatively high fraction of galaxies, 8%, are categorised as ultra diffuse galaxies. The majority of the dwarfs follow the expected scaling relations of galaxies. Globally, the GC specific frequency, S_N_, of the Perseus dwarf candidates is intermediate between those measured in the Virgo and Coma clusters. While the dwarf candidates with the largest GC counts are found throughout the Euclid field of view, the dwarfs located around the east-west strip, where most of the brightest cluster members are found, exhibit larger S_N_ values, on average. The spatial distribution of the dwarfs, GCs, and intracluster light show a main iso-density/isophotal centre displaced to the west of the bright galaxy light distribution. The ERO imaging of the Perseus cluster demonstrates the unique capability of Euclid to concurrently detect and characterise large samples of dwarf galaxies, their nuclei, and their GC systems, allowing us to construct a detailed picture of the formation and evolution of galaxies over a wide range of mass scales and environments.Peer reviewedCentre de Données astronomiques de Strasbourg (CDS)Fosalba, Pablo [0000-0002-1510-5214]Serrano, Santiago [0000-0002-0211-2861]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202520252025info:eu-repo/semantics/datasethttp://purl.org/coar/resource_type/c_ddb1text/plainhttp://hdl.handle.net/10261/398426reponame:DIGITAL.CSIC.
