Pointing calibration of GroundBIRD telescope using Moon observation data
Y. Sueno, J. J. A. Baselmans, A. H. M. Coppens +16
Understanding telescope pointing (i.e., line of sight) is important for observing the cosmic microwave background (CMB) and astronomical objects. The Moon is a candidate astronomic…
Search for Dark Photon Dark Matter in the Mass Range 41--74 using Millimeter-Wave Receiver and Radioshielding Box
