Dish Assembly Precision for HIRAX
Jennifer Studer, Devin Crichton, Alexandre Refregier +16
The paper presents photogrammetry measurements of the first 28 HIRAX dishes, showing that dish surface deviations meet specifications while feed placement meets accuracy but not pr…

A cross-bispectrum estimator for CMB-HI intensity mapping correlations
Kavilan Moodley, Warren Naidoo, Heather Prince +1
Intensity mapping of 21cm emission from neutral hydrogen promises to be a powerful probe of large-scale structure in the post-reionisation epoch. However, HI intensity mapping (IM)…
