Suzaku Observation of Merging Clusters Abell 222 and Abell 223
Yanling Chen, Wei Cui, Aurora Simionescu +2
Previous X-ray and optical studies of the galaxy cluster pair Abell 222/223 suggested the possible presence of a filamentary structure connecting the two clusters, a result that ap…
A new shock in the pre-merging cluster pair 1E2215-2216
Yanling Chen, Liyi Gu, Aurora Simionescu +3
The galaxy cluster pair 1E2216.0-0401 and 1E2215.7-0404 represents a major cluster merger in its early stages, a phase that has been scarcely explored in previous studies. Within t…
Probing the Hot Gaseous Halo of the Low-mass Disk Galaxy NGC 7793 with eROSITA and Chandra
Lin He, Zhiyuan Li, Meicun Hou +3
Galaxy formation models predict that local galaxies are surrounded by hot X-ray-emitting halos, which are technically difficult to detect due to their extended and low surface brig…
The warm-hot intergalactic medium in inter-cluster filaments -- A forecast for HUBS observations based on eRASS1 superclusters
Yuanyuan Zhao, Haiguang Xu, Ang Liu +8
Cosmological simulations indicate that nearly half of the baryons in the nearby Universe are in the warm-hot intergalactic medium (WHIM) phase, and about a half them reside in cosm…
