GroundBIRD is an experiment to observe the cosmic microwave background at 145 and 220GHz. It aims to observe the B-mode polarisation signal from inflation in the early universe. It is located at Teide Observatory, on the island of Tenerife in the Canary Islands.
GroundBIRD is an experiment to observe the cosmic microwave background at 145 and 220GHz. It aims to observe the B-mode polarisation signal from inflation in the early universe. It is located at Teide Observatory, on the island of Tenerife in the Canary Islands. The telescope was constructed to measure the B-mode signal in the polarisation of the Cosmic Microwave Background (CMB), in order to look for evidence of cosmic inflation in the early universe. It aims to observe the reionization bump at l and the recombination peak around l=200 . The name 'GroundBIRD' indicates that the telescope is ground-based, while BIRD stands for B-mode Imaging Radiation Detector. It is related to the future, similarly-named, LiteBIRD CMB satellite.
