GroundBIRD: First On-Sky Responsivity Calibration at the Teide Observatory
Alessandro Fasano, Yonggil Jo, Ricardo Tanausú Génova-Santos +12
GroundBIRD is a cosmic microwave background (CMB) experiment located at the Teide Observatory (altitude m, Spain) designed to measure large-angular-scale intensity and p…
Optimization procedure of the baffle of the GroundBIRD Telescope to mitigate stray light
Miku Tsujii, Tomonaga Tanaka, Alessandro Fasano +10
We presented the optimization procedures of the baffle mounted on the GroundBIRD telescope for measuring the polarization of the Cosmic Microwave Background~(CMB). The telescope em…
GroundBIRD Telescope: Systematics Modelization of MKID Arrays Response
Yonggil Jo, Alessandro Fasano, Eunil Won +8
Kinetic inductance detectors are widely used in millimeter- and submillimeter-wave astronomy, benefiting from their fast response and relative ease of fabrication. The GroundBIRD t…
The Simons Observatory: Detector Polarization Angle Calibration using Sparse Wire Grid with Initial Data Sets of the Small Aperture Telescope
Hironobu Nakata, Shunsuke Adachi, Kyohei Yamada +22
Improved measurements of -modes in the cosmic microwave background can be obtained through accurate calibration of the orientation of detector antennas as projected onto the sky…
Broadband, Dead-Time-Free Spectrometer Using RFSoC for WISP Dark Matter Searches
Hiroki Takeuchi, Junya Suzuki, Shunsuke Adachi +1
Ultra-light dark matter candidates, such as axions and dark photons, particularly within the mass range of eV to meV, have garnered significant research interest. However, the…
