Dark and Luminous Matter in the Coma Cluster: Probing Galaxy Cluster Assembly Through Filaments with Weak Lensing and Multiwavelength Observations
K. HyeongHan, K. Finner, M. James Jee +11
The Coma cluster (Abell 1656; ) is a nearby rich galaxy cluster and a key laboratory for studying cluster assembly in the Cosmic Web. We characterize its projected dark ma…
Unveiling the Cosmic Gems Arc at with JWST NIRCam
Larry D. Bradley, Angela Adamo, Eros Vanzella +22
We present recent JWST NIRCam imaging observations of SPT0615-JD (also known as the Cosmic Gems Arc), lensed by the galaxy cluster SPT-CL J0615-5746. The 5 arcsec long arc is the m…
J-PAS: Discovery of RaJav, a bright spatially extended Ly Nebula at z=2.25
P. T. Rahna, M. Akhlaghi, J. A. Fernández-Ontiveros +29
We report the discovery of a massive and potentially largest Ly Nebula, RaJav, at z=2.25, associated with a quasar pair: the bright SDSS~J162029.07+433451.1 (hereafter J1620+43…
Intra-Cluster Light as a Dynamical Clock for Galaxy Clusters: Insights from the MAGNETICUM, IllustrisTNG, Hydrangea and Horizon-AGN Simulations
Lucas C. Kimmig, Sarah Brough, Klaus Dolag +19
As the most massive nodes of the cosmic web, galaxy clusters represent the best probes of structure formation. Over time, they grow by accreting and disrupting satellite galaxies,…
Deep view of the intracluster light in the Coma cluster of galaxies
Yolanda Jiménez-Teja, Javier Román, Kim HyeongHan +6
Detection and study of the intracluster light in rich clusters of galaxies has been a problem of long standing challenge and interest. Using the lowest surface brightness images of…
