Tracing Early Cosmic Chemical Enrichment: A Uniform XMM-Newton Survey of Metallicity in Galaxy Groups and Clusters
Anne E Blackwell, Joel N Bregman, Sophia Chan Davis
Observed metal abundances in the intracluster medium (ICM) of galaxy groups and clusters, , exceed what is expected from present-day stellar populations alone. Galaxy clus…

Modeling the cool gas clumps in the circumgalactic medium
Hang Yang, Zhijie Qu, Joel N. Bregman +1
A major challenge in CGM studies is determining the three-dimensional (3D) properties from the observed projected observations. Here, we decompose the 3D gas density and spatial di…

CO-CHANGES II: spatially resolved IRAM 30M CO line observations of 23 nearby edge-on spiral galaxies
Yan Jiang, Jiang-Tao Li, Qing-Hua Tan +6
Molecular gas, as the fuel for star formation, and its relationship with atomic gas are crucial for understanding how galaxies regulate their star forming (SF) activities. We condu…
