Cosmological Constraints from Gas Mass Fractions of Massive, Relaxed Galaxy Clusters
Adam B. Mantz, Steven W. Allen, Rebecca E. A. Canning +14
We present updated cosmological constraints from measurements of the gas mass fractions () of massive, dynamically relaxed galaxy clusters. Our new data set has greater le…
Correlations between supermassive black holes and hot gas atmospheres in IllustrisTNG and X-ray observations
Nhut Truong, Annalisa Pillepich, Norbert Werner
Recent X-ray observations have revealed remarkable correlations between the masses of central supermassive black holes (SMBHs) and the X-ray properties of the hot atmospheres perme…
Multiwavelength classification of X-ray selected galaxy cluster candidates using convolutional neural networks
Matej Kosiba, Maggie Lieu, Bruno Altieri +15
Galaxy clusters appear as extended sources in XMM-Newton images, but not all extended sources are clusters. So, their proper classification requires visual inspection with optical…
Voyage through the Hidden Physics of the Cosmic Web
A. Simionescu, S. Ettori, N. Werner +27
The majority of the ordinary matter in the local Universe has been heated by strong structure formation shocks and resides in a largely unexplored hot, diffuse, X-ray emitting plas…
Constraining Gas Motions in the Intra-Cluster Medium
A. Simionescu, J. ZuHone, I. Zhuravleva +9
The detailed velocity structure of the diffuse X-ray emitting intra-cluster medium (ICM) remains one of the last missing key ingredients in understanding the microphysical properti…
A uniform metallicity in the outskirts of massive, nearby galaxy clusters
O. Urban, N. Werner, S. W. Allen +2
Suzaku measurements of a homogeneous metal distribution of Solar in the outskirts of the nearby Perseus cluster suggest that chemical elements were deposited and mixed i…
