Mass Accretion and its Effects on the Self-Similarity of Gas Profiles in the Outskirts of Galaxy Clusters
Erwin T. Lau, Daisuke Nagai, Camille Avestruz +2
Galaxy clusters exhibit remarkable self-similar behavior which allows us to establish simple scaling relationships between observable quantities and cluster masses, making galaxy c…
Turbulent Heating in Galaxy Clusters Brightest in X-rays
I. Zhuravleva, E. Churazov, A. A. Schekochihin +9
The hot, X-ray-emitting intracluster medium (ICM) is the dominant baryonic constituent of clusters of galaxies. In the cores of many clusters, radiative energy losses from the ICM…
SPT-3G: A Next-Generation Cosmic Microwave Background Polarization Experiment on the South Pole Telescope
B. A. Benson, P. A. R. Ade, Z. Ahmed +61
We describe the design of a new polarization sensitive receiver, SPT-3G, for the 10-meter South Pole Telescope (SPT). The SPT-3G receiver will deliver a factor of ~20 improvement i…
Analysis of Sunyaev-Zel'dovich Effect Mass-Observable Relations using South Pole Telescope Observations of an X-ray Selected Sample of Low Mass Galaxy Clusters and Groups
J. Liu, J. Mohr, A. Saro +63
(Abridged) We use 95, 150, and 220GHz observations from the SPT to examine the SZE signatures of a sample of 46 X-ray selected groups and clusters drawn from ~6 deg^2 of the XMM-BC…
Chandra ACIS-I particle background: an analytical model
Iacopo Bartalucci, Pasquale Mazzotta, Hervé Bourdin +1
Aims: Imaging and spectroscopy of X-ray extended sources require a proper characterisation of a spatially unresolved background signal. This background includes sky and instrumenta…
Testing X-ray Measurements of Galaxy Cluster Outskirts with Cosmological Simulations
Camille Avestruz, Erwin T. Lau, Daisuke Nagai +1
The study of galaxy cluster outskirts has emerged as one of the new frontiers in extragalactic astrophysics and cosmology with the advent of new observations in X-ray and microwave…
