This year the Murchison Widefield Array annual December meeting was hosted by Arizona State University, here in Tempe. In celebration of over a year of active observing the meeting was opened to attendance and contributions from the wider community. The result was a rare convocation of the low frequency radio astronomy community. Topics ranged from […]

Paper Title: A Flux Scale for Southern Hemisphere 21cm EoR Experiments arxiv,data,fits If you look at typical catalogs of sources in the southern hemisphere epoch of reionization band you soon realize why measurements often disagree by 20%. Even the brightest sources one would use for calibration are uncertain. As you can see from the plot to

Title: The precision and accuracy of early Epoch of Reionization foreground models: comparing MWA and PAPER 32-antenna source catalogs This paper compares the fluxes in the first PAPER and MWA catalogs. These sources are the brightest foregrounds in front of the EoR HI emission. Various estimates suggest that we have to subtract these guys to anywhere
