This is the 2016 annual collaboration meeting for the Tianlai Project - a Dark Energy Radio Observation Experiment (http://tianlai.bao.ac.cn). It will include a number of presentations on related efforts (related in terms of science or instrumentation) by scientists outside the collaboration.
BACKGROUND: In the past few years there have been significant advances in implementing 21cm intensity mapping to measure large scale structure in huge volumes of the universe: In Canada the Canadian Hydrogen Intensity Mapping Experiment (CHIME) is now moving from prototype to the full experiment; in China the Tianlai experiment’s prototype is now in operation; the Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is beginning in South Africa. Analysis of Tianlai data has recently been funded by the US National Science Foundation.
