Mapping our Universe in 3D with MITEoR
Haoxuan Zheng, Max Tegmark, Victor Buza +33
Mapping our universe in 3D by imaging the redshifted 21 cm line from neutral hydrogen has the potential to overtake the cosmic microwave background as our most powerful cosmologica…
A Flux Scale for Southern Hemisphere 21cm EoR Experiments
Daniel C. Jacobs, Aaron R. Parsons, James E. Aguirre +14
We present a catalog of spectral measurements covering a 100-200 MHz band for 32 sources, derived from observations with a 64-antenna deployment of the Donald C. Backer Precision A…
Fine-scale structure of the quasar 3C 279 Measured with 1.3 mm very long baseline interferometry
Ru-Sen Lu, Vincent L. Fish, Kazunori Akiyama +30
We report results from 5-day VLBI observations of the well-known quasar 3C 279 at 1.3 mm (230 GHz) in 2011. The measured nonzero closure phases on triangles including stations in A…
New Limits on 21cm EoR From PAPER-32 Consistent with an X-Ray Heated IGM at z=7.7
Aaron R. Parsons, Adrian Liu, James E. Aguirre +14
We present new constraints on the 21cm Epoch of Reionization (EoR) power spectrum derived from 3 months of observing with a 32-antenna, dual-polarization deployment of the Donald C…
Opening the 21cm EoR Window: Measurements of Foreground Isolation with PAPER
Jonathan C. Pober, Aaron R. Parsons, James E. Aguirre +13
We present new observations with the Precision Array for Probing the Epoch of Reionization (PAPER) with the aim of measuring the properties of foreground emission for 21cm Epoch of…
