GroundBIRD, Radio telescope at Teide Observatory, Tenerife, Spain
The GroundBIRD telescope contains two mirrors in a Mizuguchi-Dragone configuration with a 30-centimeter diameter to study cosmic microwave background radiation.
The telescope installation moved from Japan to the Teide Observatory in 2019 following extensive testing and development phases starting in 2014.
The presence of Japanese Ambassador Kenji Hiramatsu at the facility in 2020 emphasized the international research connections between Spain and Japan.
Located at 2400 meters elevation, the telescope maps 40 percent of the sky using specialized detectors cooled to 250 millikelvins for optimal signal detection.
GroundBIRD measures specific features of cosmic microwave background polarization at frequencies of 145 and 220 gigahertz to examine early universe conditions.
