Radiofrequency Ice Dielectric Measurements at Summit Station, Greenland

TL;DR: In this paper , the authors reported that after averaging 10000 echo triggers, reflected signal observable over the thermal floor (to depths of approximately 1500 m) are consistent with being entirely coherent, internal layer reflection coefficients are measured at approximately -60 to -70 dB, birefringent effects for vertically propagating signals are smaller by an order of magnitude relative to comparable studies performed at South Pole, and within their experimental limits, glacial ice is non-dispersive over the frequency band relevant for neutrino detection experiments.

BICEP/Keck. XVII. Line-of-sight Distortion Analysis: Estimates of Gravitational Lensing, Anisotropic Cosmic Birefringence, Patchy Reionization, and Systematic Errors

TL;DR: In this paper , the authors present estimates of line-of-sight distortion fields derived from the 95 and 150 GHz data taken by BICEP2, BiceP3, and the Keck Array up to the 2018 observing season, leading to cosmological constraints and a study of instrumental and astrophysical systematics.

High-precision scanning water vapor radiometers for cosmic microwave background site characterization and comparison

TL;DR: In this article, a campaign to perform a coordinated characterization of current and potential future observing sites using scanning 183 GHz water vapor radiometers (WVRs) was undertaken, with two identical WVR units; one at South Pole, Antarctica, and the other at Summit Station, Greenland.
Journal ArticleDOI

Design and initial performance of the prototype for the BEACON instrument for detection of ultrahigh energy particles

TL;DR: The Beamforming Elevated Array for COsmic Neutrinos (BEACON) is a planned neutrino telescope designed to detect radio emission from upgoing air showers generated by ultrahigh energy tau neutrinos interactions in the Earth as mentioned in this paper .
