Abstract:

LiteBIRD is a future satellite mission designed to observe the polarization of the cosmic microwave background radiation in order to probe the inflationary universe. LiteBIRD is set to observe the sky using three telescopes with transition-edge sensor bolometers. In this work we estimated the LiteBIRD instrumental sensitivity using its current design. We estimated the detector noise due to the optical loadings using physical optics and ray-tracing simulations. The noise terms associated with thermal carrier and readout noise were modeled in the detector noise calculation. We calculated the observational sensitivities over fifteen bands designed for the LiteBIRD telescopes using assumed observation time efficiency.

A born again 32-meter radio telescope for Mexico

Proceedings of SPIE - The International Society for Optical Engineering 12182 (2022)

Authors:

SE Kurtz, AC Taylor, ME Jones, DM Gale, EI Medel, A Pollak, C Liu

Abstract:

The town of Tulancingo de Bravo in the Mexican state of Hidalgo is the site of Mexico's original satellite earth station. Although unused for satellite communications for over 15 years, the site hosts two 32-meter dishes and over a dozen smaller dishes, ranging from 2 to 11 meters in size, along with a substantial supporting infrastructure. Beginning in 2018 we have led a project to convert one or more of the earth station's telecommunications antennas into a radio telescope suitable for research-grade astronomical observations. Here we present a brief history and motivation for the conversion project, provide technical details of the upgraded system with emphasis on the receiver, describe our progress to date, and mention plans for the final stages of the conversion.
