20.500.12556/RUL-165233 Modeling and subtracting diffuse cluster light in JWST images a relation between the spatial distribution of globular clusters, dwarf galaxies, and intracluster light in the lensing cluster SMACS 0723 We present a methodology for modeling and removing light from cluster galaxies and intracluster light (ICL) from James Webb Space Telescope images of gravitational lensing clusters. We apply our method to Webb’s First Deep Field the SMACS 0723 Early Release Observations and use the ICL-subtracted images to select a sample of globular clusters (GCs) and dwarf galaxies within the cluster. We compare the spatial distributions of these two samples with our models of the galaxy and ICL light, finding significant similarities. In particular, we find that GCs trace the diffuse ICL, while dwarf galaxies are centrally concentrated near the cluster center We quantify the relationship between the surface density of compact sources and total cluster light, demonstrating a significant, tight correlation. We repeat our methodology and compare distributions of GCs with the dark matter surface density and find a comparable result. Our findings suggest a common origin for GCs and diffuse ICL, with stripping from massive galaxies as they merge with the cluster being a plausible scenario. galaxy clusters high-redshift galaxy clusters globular star clusters galaxy evolution true false true Angleški jezik Ni določen Članek v reviji 2024-11-27 16:36:07 2024-11-27 16:36:08 2025-11-26 15:31:49 0000-00-00 00:00:00 2024 0 0 16 str. no. 1, art. 76 Vol. 975 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 524.8 1538-4357 10.3847/1538-4357/ad7735 216740099 Martis_2024_ApJ_975_76.pdf Martis_2024_ApJ_975_76.pdf 1 D3557C995A0062EC8D63C1D2FBBB7596 f435a0dee218dc1096b9b0e7608554d97b7f22ef86c436e6afef4daa693e423d 59cf94d5-acd6-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196289 https://iopscience.iop.org/article/10.3847/1538-4357/ad7735 0 d636f139-cad0-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=222577 Fakulteta za matematiko in fiziko 0 0 0
