Kavli Affiliate: Chao-Lin Kuo | Summary:A commonly used technology for axion and other wave-like dark matter searches is a microwave resonator. In such experiments, the detected signal strength depends on the coupling between the resonator and the microwave transmission line that delivers power to the amplifier. In Axion Dark Matter eXperiment (ADMX) and other cavity […]
Kavli Affiliate: Aaron Roodman | Summary:The NSF-DOE Vera C. Rubin Observatory will complete its ten-year Legacy Survey of Space and Time (LSST) in the mid-2030s. Its 8.4 m aperture and 9.6 square degree field of view give it an étendue unmatched by any facility planned for that era. The Rubin 2036: Opportunities for Discovery workshop […]
Kavli Affiliate: Susan Clark | Summary:Trapped-ion, neutral-atom, and circuit QED quantum computers naturally enable coupled qubit-boson simulations. Boson-fermion interactions arise in quantum field theory, where renormalization is required to obtain finite results. We study one of the simplest examples of a coupled fermion-boson system, the static Yukawa model, on the QSCOUT trapped-ion system. We use […]
Kavli Affiliate: Sven Herrmann | Summary:Germanium charge-coupled devices (Ge-CCDs) extend CCD imaging beyond the silicon cutoff and are candidate detectors for the near-infrared channel of future astronomical instruments, in particular the spectrographs of next-generation wide-field surveys. We report the laboratory characterization at Brookhaven National Laboratory (BNL) of a prototype fabricated at MIT Lincoln Laboratory. We […]
Kavli Affiliate: Eli Rykoff | Summary:The NSF-DOE Vera C. Rubin Observatory is executing the Legacy Survey of Space and Time (LSST) as its prime mission, producing a series of data releases over the ten-year survey. The LSST Science Pipelines Software will be used to create these data releases and to perform the nightly prompt processing […]
Kavli Affiliate: Peter Graham | Summary:We consider the inelastic dark matter interpretation of the recent 248 keV event observed by LZ and identify different experiments that could test it. Details of the underlying model and the ability of complementary experiments to test it depend significantly on the high-velocity tail of the dark matter distribution. We […]
Kavli Affiliate: W. L. Kimmy Wu | Summary:Recent cosmological data hint at a neutrino mass sum below the minimum value allowed by the neutrino mass oscillation experiments, with a preference for the opposite of massive neutrinos ("negative" neutrino masses). Since massive neutrinos impact the expansion history of the Universe, which in turn modifies the growth […]
Kavli Affiliate: Bruce Macintosh | Summary:Observations of debris disks provide a valuable window to investigate the formation and evolution of planetary systems. We present high-contrast JWST/NIRCam observations of CPD-72 2713, a 24 Myr-old star that belongs to the $β$ Pic moving group. We obtained the first scattered-light images of the disk in both F210M and […]
Kavli Affiliate: Risa Wechsler | Summary:The abundance and properties of low-mass dark matter subhalos can be inferred by measuring the density and velocity structure of stellar streams, testing physical models of dark matter. Which streams make the most promising dark matter detectors, and which subhalos would they encounter? We use the semi-analytic model galacticus to […]
Kavli Affiliate: Zeeshan Ahmed | Summary:We present the design, implementation, and initial performance of a highly multiplexed cryogenic superconducting detector readout system in the context of its deployment to the Simons Observatory large-aperture telescope (LAT). The Simons Observatory is a cosmic microwave background experiment located at 5,200 m in Chile’s Atacama Desert. In addition to […]
