Recent Results from the Precision Array for Probing the Epoch of Reionization (PAPER) Experiment in South Africa

The goal of the Precision Array for Probing the Epoch of Reionization (PAPER) experiment is detection of the power spectrum of the fluctuations of 21cm emission at high redshift (7-11) when the first stars were forming. The design of PAPER consists of broad-band dipoles, active balun, coaxial cable transmission, analog gain/filtering, digitization and correlation. Analysis of PAPER data requires RFI excision, iterative calibration and source removal, and full-hemisphere imaging. A 16-dipole engineering test array has been deployed at the NRAO Green Bank, WV site; a 4-dipole was deployed in Western Australia in 2007. See Parsons et al. arXiv:0904.2334 for a brief description of the status of the experiment in the middle of 2009. This poster will describe the first deployment of a PAPER experiment at the Karoo SKA development site in South Africa.
