The beamformed trigger of RNO-G: its design and in-field performance

S. Agarwal, J. A. Aguilar, Nathaniel Alden, S. Ali et autres

Abstract The Radio Neutrino Observatory in Greenland (RNO-G) is a neutrino detector under construction at Summit Station, with 8 out of a planned 35 stations currently deployed. We have designed and deployed a new phased array (PA) trigger based on delay-and-sum beamforming …

Measurement of the Full Shape of the Thermal Sunyaev–Zel’dovich Power Spectrum from the South Pole Telescope and Herschel–SPIRE Observations

S. Raghunathan, P Ade, D. Anbajagane, Adam J. Anderson et autres

Abstract We present a measurement of the full shape of the power spectrum of the thermal Sunyaev–Zel’dovich (tSZ) effect down to arcminute scales using cosmic microwave background (CMB) data from the South Pole Telescope (SPT) over a roughly 100 deg 2 field. …

BICEP/Keck. XIX. Extremely Thin Composite Polymer Vacuum Windows for BICEP and Other High-throughput Millimeter-wave Telescopes

P. A. R. Ade, Zeeshan Ahmed, Mandana Amiri, D. Barkats et autres

Abstract Millimeter-wave refracting telescopes targeting the degree-scale structure of the cosmic microwave background (CMB) have recently grown to diffraction-limited apertures of over 0.5 m. These instruments are entirely housed in vacuum cryostats to support their subkelvin bolometric detectors and to minimize radiative …

Observation of In-Ice Askaryan Radiation from High-Energy Cosmic Rays

Nathaniel Alden, S. Ali, P. Allison, S. Archambault et autres

We present the first experimental evidence for in-ice Askaryan radiation-coherent charge-excess radio emission-from high-energy particle cascades developing in the Antarctic ice sheet. In 208 days of data recorded with the phased array instrument of the Askaryan Radio Array, a previous analysis has …

Probing the firn refractive index profile using antenna response

J. A. Aguilar, Nathaniel Alden, P. Allison, O. Botner et autres

Abstract The Radio Neutrino Observatory-Greenland (RNO-G, at Summit Station) experiment comprises an extensive fat-dipole antenna array deployed into ice boreholes over an eventual area of approximately 35 km 2 . Since the RNO-G experimental sensitivity depends on the radio-frequency properties of the …

SPT-3G D1: Constraints on inflationary gravitational waves with two years of SPT-3G data

Christian L. Reichardt, Adam J. Anderson, Behzad Ansarinejad, M. Archipley et autres

We present a measurement of the $B$-mode polarization power spectrum of the cosmic microwave background anisotropies at $32\ensuremath{\le}\ensuremath{\ell}<502$ for three bands centered at 95, 150, and 220 GHz using data from the SPT-3G receiver on the South Pole Telescope. This work uses …

Radio emission from airplanes as observed with RNO-G

S. Agarwal, J. A. Aguilar, Nathaniel Alden, S. Ali et autres

Abstract This paper describes how intentional and unintentional radio emission from airplanes is recorded with the Radio Neutrino Observatory Greenland (RNO-G). We characterize the received signals and define a procedure to extract a clean set of impulsive signals. These signals are highly …

Cosmic-Ray Physics in the PeV to EeV Energy Range with the IceCube-Gen2 Surface Array

Frank Schröder, M. Ackermann, Jenni Adams, Sanjib Kumar Agarwalla et autres

IceCube-Gen2 is a proposed neutrino observatory at the South Pole that will build on the success of IceCube and will also serve as a unique detector for cosmic-ray air showers. Analogous to the IceTop surface array over IceCube’s deep optical detector, IceCube-Gen2 …

A prototype station of the IceCube-Gen2 Surface Array at the Pierre Auger Observatory

Stef Verpoest, Benjamin Flaggs, Carmen Merx, M. Ackermann et autres

The detection of extensive air showers using radio antennas has evolved into a mature technique, complementing particle detector arrays by providing sensitivity to the longitudinal development of the showers and enabling an independent determination of the cosmic-ray energy. Both the Pierre Auger …

Simulation of In-ice Askaryan Radiation from Air Shower Cores for Cosmic Rays Search with RNO-G.

Noppadol Punsuebsay, Agnieszka Leszczyńska, D. Seckel, Sanyukta Agarwal et autres

The Radio Neutrino Observatory in Greenland (RNO-G) was designed to detect ultra-high energy neutrinos through Askaryan radiation. The detector utilizes radio antennas that are deployed both just below the ice surface and inside the ice boreholes to observe radio signals that come …

Identifying Cosmic Ray Radio Emission in RNO-G’s Deep Antennas

Bryan L. Hendricks, Sanyukta Agarwal, J. A. Aguilar, Nathaniel Alden et autres

Ultra-high-energy neutrinos are an invaluable messenger for learning about the most energetic and distant astrophysical processes in the universe. Detecting them is challenging due to their extremely low flux and small cross section, necessitating immense detection volumes. The Radio Neutrino Observatory in …
