cds-question@unistra.frgalaxy-clustersdwarf-galaxiesglobular-star-clustersinfrared-astronomyWe present an analysis of globular clusters (GCs) of dwarf galaxies in the Perseus galaxy cluster to explore the relationship between dwarf galaxy properties and their GCs, which offer important clues on the origin and subsequent evolution of dwarf galaxies. Our focus is on GC numbers (N_GC_) and GC half-number radii (R_GC_) around dwarf galaxies, and their relations with host galaxy stellar masses (M*), central surface brightnesses ({mu}_0_), and effective radii (Re). Interestingly, we find that at a given stellar mass, R_GC_ is almost independent of the host galaxy {mu}_0_ and Re, while GC/Re depends on {mu}_0_ and Re; lower surface brightness and diffuse dwarf galaxies show GC/Re~1 while higher surface brightness and compact dwarf galaxies show R_GC_/Re~1.5-2. This means that for dwarf galaxies of similar stellar mass, the GCs have a similar median extent; however, their distribution is different from the field stars of their host. Additionally, low surface brightness and diffuse dwarf galaxies on average have a higher N_GC_ than high surface brightness and compact dwarf galaxies at any given stellar mass. We also find that UDGs (ultra-diffuse galaxies) and non-UDGs in the sample have similar R_GC_, while UDGs have smaller R_GC_/Re (typically less than 1) and 3-4 times higher N_GC_ than non-UDGs. Furthermore, examining nucleated versus not-nucleated dwarf galaxies, we find that for M*>10^8^M_{sun}_ nucleated dwarf galaxies seem to have smaller R_GC_ and R_GC_/Re with no significant differences seen between their N_GC_, except at M*<10^8^M_{sun}_ where the nucleated dwarf galaxies tend to have a higher N_GC_. Lastly, we explore the stellar-to-halo mass ratio (SHMR) of dwarf galaxies (halo mass based on N_GC_) and conclude that the Perseus cluster dwarf galaxies follow the expected SHMR at z=0 extrapolated down to M*=10^6^M_{sun}_2025A&A...703A.184Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/703/A184CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/692/A96 : NGC 6397 Euclid/Gaia internal kinematics (Libralato+, 2024)J/A+A/696/A80 : LDN 1495 free-floating planetary mass objects (Bouy+, 2025)J/A+A/697/A8 : NGC 6254 (M10) and NGC 6397 Euclid photometry (Massari+, 2025)J/A+A/697/A11 : Euclid Early Release Observations.
