Development of a planar cable-driven parallel robot for submillimeter and terahertz beam mapping measurements

Evan C. Mayer, Ian N. Lowe, Daniel P. Marrone, James J. Bock et autres

The spatial sensitivity pattern of millimeter-wavelength receivers is an important diagnostic of performance and is affected by the alignment of coupling optics. Characterization can be challenging in the field, particularly in the decentered and tightly packed optical configurations that are employed for …

Measurements of the temperature and E -mode polarization of the cosmic microwave background from the full 500-square-degree SPTpol dataset

T.-L. Chou, P. A. R. Ade, A. J. Anderson, Jason E. Austermann et autres

The authors build upon, and extend, previous work to now use the Full 500-square-degree South Pole Telescope Cosmic Microwave Background (CMB) polarization dataset. They confirm previous \ensuremath{\Lambda}CDM-consistent results and obtain the most sensitive measurements of the lensed-CMB damping tail to date.

Multiprobe cosmology from the abundance of SPT clusters and DES galaxy clustering and weak lensing

S. Bocquet, S. Grandis, E. Krause, C. To et autres

Cosmic shear, galaxy clustering, and the abundance of massive halos each probe the large-scale structure of the Universe in complementary ways. We present cosmological constraints from the joint analysis of the three probes, building on the latest analyses of the lensing-informed abundance …
