Abstract Understanding telescope pointing (i.e. line of sight) is important for observing the cosmic microwave background (CMB) and astronomical objects. The Moon a candidate source calibration. Although visible size (30′) larger than that planets, we can frequently observe once month with high signal-to-noise ratio. We developed method performing calibration using observational data from Moon. considered tilts axes as well encoder collimation offsets In addition, evaluated effects...
The cutting-edge superconducting detector, Microwave Kinetic Inductance Detector（MKID） has been popular in the field of astronomical radio observations such as Cosmic Background（CMB）, star-forming regions, and galaxy surveying. MKID is a resonator-based detector which scalability to exceed O（1,000） pixels one readout line. photon-noise-limited sensitivity can be achieved with hybrid-type consists two materials. arrays are utilized “GroundBIRD” “Tsukuba-KID camera” projects led by Japanese...
GroundBIRD is a ground-based cosmic microwave background (CMB) experiment for observing the polarization pattern imprinted on large angular scales (ℓ > 6 ) from Teide Observatory in Tenerife, Spain. Our primary scientific objective precise measurement of optical depth τ (σ(τ ∼ 0.01) to reionization epoch Universe cross-check systematic effects measurements made by previous experiments. observes wide sky area Northern Hemisphere (∼ 40% full sky) while continuously rotating telescope at high...
