Continuous Ultra-Low-Frequency Solar Radio Monitoring with ALBATROS from the High Arctic
Aman Chokshi, Mohan Agrawal, Christopher Barbarie +18
In the Canadian High Arctic, nearly five months of continuous daylight enable uninterrupted low-frequency solar monitoring. We present the first solar science results from the Arra…
PEACC - Precision Emitter for 21 cm Array Coherent Calibration
Kalyani Bhopi, Morgan Cole, Mallory Helfenbein +4
Foreground mitigation remains a central challenge for 21 cm intensity mapping experiments, which require precise, wideband calibration of telescope beams and gains. We present the…
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…
Beam Maps of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Measured with a Drone
Will Tyndall, Alex Reda, J. Richard Shaw +14
We present beam measurements of the CHIME telescope using a radio calibration source deployed on a drone payload. During test flights, the pulsing calibration source and the telesc…
