The spectral index of polarized diffuse Galactic emission between 30 and 44 GHz
Luke Jew, Richard Grumitt
We present an estimate of the polarized spectral index between the Planck 30 and 44 GHz surveys in pixels across the entire sky. We use an objective reference prior tha…

HI 21cm Cosmology and the Bi-spectrum: Closure Diagnostics in Massively Redundant Interferometric Arrays
C. L. Carilli, Bojan Nikolic, Nithyanandan Thyagarajan +62
New massively redundant low frequency arrays allow for a novel investigation of closure relations in interferometry. We employ commissioning data from the Hydrogen Epoch of Reioniz…
