Strain gauge plethysmography (SGP) is a non-invasive method used in the detection of deep venous thrombosis (DVT). The technique is based on the measurement of calf volume changes in response to venous occlusion by a thigh cuff, the volume changes reflecting the rates of arterial inflow and venous outflow. A numerical model of the blood circulation within(More)
Using Hubble Space Telescope slitless grism data, we report the spectroscopic confirmation of two distant structures at ~ z 2 associated with powerful high-redshift radio-loud active galactic nuclei(AGNs). These rich structures, likely (forming) clusters, are among the most distant structures currently known, and were identified on the basis of(More)
We use a sample of 37 of the densest clusters and protoclusters across 1.3 6 z 6 3.2 from the Clusters Around Radio-Loud AGN (CARLA) survey to study the formation of massive cluster galaxies. We use optical i′-band and infrared 3.6μm and 4.5μm images to statistically select sources within these protoclusters and measure their median observed colours; 〈i′ −(More)
We report on the discovery of a z=1.58 mature cluster around the high-redshift radio galaxy 7C 1753+6311, first identified in the Clusters Around Radio-loud active galactic nuclei survey. Two-thirds of the excess galaxies within the central 1 Mpc lie on a red sequence with a color that is consistent with an average formation redshift of zf∼3. We show(More)
