Deep-learning-based prediction of Precipitable Water Vapor in the Chajnantor area
Alison Matus-Bello, Silvia E. Restrepo, Ricardo Bustos +7
Astronomical observations at millimeter and submillimeter wavelengths heavily depend on the amount of Precipitable Water Vapor (PWV) in the atmosphere, directly affecting the sky t…

Estimating Soil Electrical Parameters in the Canadian High Arctic from Impedance Measurements of the MIST Antenna Above the Surface
I. Hendricksen, R. A. Monsalve, V. Bidula +13
The MIST experiment aims to detect the cosmological 21-cm signal through sky observations at 25-125 MHz using a wide-beam antenna. The antenna is mounted above the soil and the bea…

Using the antenna impedance to estimate soil electrical parameters for the MIST global 21-cm experiment
Cinthia Altamirano, Ricardo Bustos, Raul A. Monsalve +11
Radio experiments trying to detect the global ~cm signal from the early Universe are very sensitive to the electrical properties of their environment. For ground-based experime…
