An RFSoC-Based 100 GbE Spectrometer/Correlator for the Baryon Mapping Experiment: Digital Backend Design and On-Sky Validation
Liju Philip, Paul O'Connor, Benjamin Saliwanchik +2
We describe the implementation and on-sky commissioning of a two-input spectrometer/correlator built on a Xilinx ZCU208 Radio Frequency System-on-Chip (RFSoC) and deployed on the B…
Dish Assembly Precision for HIRAX
Jennifer Studer, Devin Crichton, Alexandre Refregier +16
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array that is being deployed at the South African Radio Astronomy Observatory (SARAO) Squ…
Joint Estimation of Properties of the Lunar Subsurface and Galactic Foregrounds with LuSEE-Night
Fatima Yousuf, Zack Li, Stuart D. Bale +36
The Lunar Surface Electromagnetics Experiment (LuSEE-Night) is a joint NASA-DOE-ESA low-frequency radio telescope that will reach the lunar far side in 2027. The unknown dielectric…
Linear map-making with LuSEE-Night
Hugo Camacho, Kaja M. Rotermund, Anže Slosar +32
LuSEE-Night is a pathfinder radio telescope on the lunar far side employing four 3-m monopole antennas arranged as two horizontal cross pseudo-dipoles on a rotational stage and sen…
Drone Beam Mapping of the TONE Radio Dish Array
Emily R. Kuhn, Will Tyndall, Benjamin R. B. Saliwanchik +3
Drone-based beam measurements are a promising avenue to tackle the critical challenge of calibration for 21 cm cosmology telescopes. In this paper, we introduce a new drone-based c…
LuSEE-Night power requirements and power generation strategy
Benjamin R. B. Saliwanchik, Sven Herrmann, Ivan Kotov +4
The Lunar Surface Electromagnetics Experiment at Night (LuSEE-Night) is a project designed to investigate the feasibility of observing the Cosmic Dark Ages using an instrument on t…
