Quantum metrology of low frequency electromagnetic modes with frequency upconverters

Kavli Affiliate: Kent D. Irwin | First 5 Authors: Stephen E. Kuenstner, Elizabeth C. van Assendelft, Saptarshi Chaudhuri, Hsiao-Mei Cho, Jason Corbin | Summary: We describe the RF Quantum Upconverter (RQU) and describe its application to quantum metrology of electromagnetic modes between dc and the Very High Frequency band (VHF) ($lesssim$300MHz). The RQU uses a […]

The Aemulus Project VI: Emulation of beyond-standard galaxy clustering statistics to improve cosmological constraints

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Kate Storey-Fisher, Jeremy Tinker, Zhongxu Zhai, Joseph DeRose, Risa H. Wechsler | Summary: There is untapped cosmological information in galaxy redshift surveys in the non-linear regime. In this work, we use the AEMULUS suite of cosmological $N$-body simulations to construct Gaussian process emulators of galaxy clustering […]

Large-Scale Spatial Cross-Calibration of Hinode/SOT-SP and SDO/HMI

Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: David F. Fouhey, Richard E. L. Higgins, Spiro K. Antiochos, Graham Barnes, Marc L. DeRosa | Summary: We investigate the cross-calibration of the Hinode/SOT-SP and SDO/HMI instrument meta-data, specifically the correspondence of the scaling and pointing information. Accurate calibration of these datasets gives the correspondence needed […]
