Measuring the Clustering of tSZ-Selected Galaxy Clusters with SPT-3G
E. S. Martsen, D. Anbajagane, L. E. Bleem +96
We present a measurement of the spatial clustering of galaxy clusters selected via the thermal Sunyaev-Zel'dovich (tSZ) signal. Using a cluster catalog derived from five years of S…
Galaxy Clusters Selected via the Sunyaev-Zel'dovich Effect in 5 year data from the SPT-3G Main Survey
L. E. Bleem, M. Klein, K. Kornoelje +148
We report a new galaxy cluster catalog, selected using the thermal Sunyaev-Zel'dovich (SZ) effect, from 5 years of observations of the SPT-3G Main field. Drawn from arcminute-resol…
Discovery of a Ultra Steep Spectrum Radio Halo in the MeerKAT-South Pole Telescope Survey
Isaac S. Magolego, Roger P. Deane, Kshitij Thorat +15
Radio halos are diffuse synchrotron sources that trace the turbulent intracluster medium (ICM) of galaxy clusters. However, their origin remains unknown. Two main formation models…
The z=1.03 Merging Cluster SPT-CL J0356-5337: New Strong Lensing Analysis with HST and MUSE
Grace Smith, Guillaume Mahler, Kate Napier +8
We present a strong lensing analysis and reconstruct the mass distribution of SPT-CL J0356-5337, a galaxy cluster at redshift z = 1.034. Our model supersedes previous models by mak…
Multiprobe Cosmology from the Abundance of SPT Clusters and DES Galaxy Clustering and Weak Lensing
S. Bocquet, S. Grandis, E. Krause +216
Cosmic shear, galaxy clustering, and the abundance of massive halos each probe the large-scale structure of the Universe in complementary ways. We present cosmological constraints…
SZ-X-ray Surface Brightness Fluctuations in the SPT-XMM clusters
Charles Romero, Massimo Gaspari, Gerrit Schellenberger +10
The hot plasma in galaxy clusters, the intracluster medium (ICM), is expected to be shaped by subsonic turbulent motions, which are key for heating, cooling, and transport mechanis…
