Constraints on the Thermal Contents of the X-Ray Cavities of Cluster MS 0735.6+7421 with Sunyaev–Zel’dovich Effect Observations Open
Outbursts from active galactic nuclei (AGN) can inflate cavities in the intracluster medium (ICM) of galaxy clusters and are believed to play the primary role in offsetting radiative cooling in the ICM. However, the details of how the ener…

The Event Horizon Telescope (EHT) is a very-long-baseline interferometry (VLBI) experiment that aims to observe supermassive black holes with an angular resolution that is comparable to the event horizon scale. The South Pole occupies an i…

PERSISTENT ASYMMETRIC STRUCTURE OF SAGITTARIUS A* ON EVENT HORIZON SCALES Open
The Galactic Center black hole Sagittarius A* (Sgr A*) is a prime observing target for the Event Horizon Telescope (EHT), which can resolve the 1.3 mm emission from this source on angular scales comparable to that of the general relativist…

THE MASSIVE AND DISTANT CLUSTERS OF WISE SURVEY. III. SUNYAEV-ZEL'DOVICH MASSES OF GALAXY CLUSTERS AT z ~ 1 Open
We present CARMA 30 GHz Sunyaev–Zel'dovich (SZ) observations of five high-redshift (z [> over ~] 1), infrared-selected galaxy clusters discovered as part of the all-sky Massive and Distant Clusters of WISE Survey (MaDCoWS). The SZ decremen…

Optical and Sunyaev–Zel'dovich observations of a new sample of distant rich galaxy clusters in the ROSAT All Sky Open
Finding a sample of the most massive clusters with redshifts z > 0.6 can provide an interesting consistency check of the Λ cold dark matter (ΛCDM) model. Here, we present results from our search for clusters with 0.6 ≲ z ≲ 1.0 wh…
