Kavli Affiliate: Noah Kurinsky | First 5 Authors: Robin Anthony-Petersen, Andreas Biekert, Raymond Bunker, Clarence L. Chang, Yen-Yung Chang | Summary: The performance of superconducting qubits is degraded by a poorly characterized set of energy sources breaking the Cooper pairs responsible for superconductivity, creating a condition often called “quasiparticle poisoning". Both superconducting qubits and low […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: D. C. Goldfinger, P. A. R. Ade, Z. Ahmed, M. Amiri, D. Barkats | Summary: Observations of the Cosmic Microwave Background rely on cryogenic instrumentation with cold detectors, readout, and optics providing the low noise performance and instrumental stability required to make more sensitive measurements. It is […]
Kavli Affiliate: Daniel R. Wilkins | Summary:Single electron Sensitive Read Out (SiSeRO) is a novel on-chip charge detector output stage for charge-coupled device (CCD) image sensors. Developed at MIT Lincoln Laboratory, this technology uses a p-MOSFET transistor with a depleted internal gate beneath the transistor channel. The transistor source-drain current is modulated by the transfer […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: A. Soliman, P. A. R. Ade, Z. Ahmed, M. Amiri, D. Barkats | Summary: Constraining the Galactic foregrounds with multi-frequency Cosmic Microwave Background (CMB) observations is an essential step towards ultimately reaching the sensitivity to measure primordial gravitational waves (PGWs), the sign of inflation after the Big-Bang […]
Kavli Affiliate: Roger Blandford | Summary:The dichotomy between radio-loud (RL) and radio-quiet (RQ) active galactic nuclei (AGN) is thought to be intrinsically related to radio jet production. This difference may be explained by the presence of a strong magnetic field (B-field) that enhances, or is the cause of, the accretion activity and the jet power. […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Niccolò Bucciantini, Riccardo Ferrazzoli, Matteo Bachetti, John Rankin, Niccolò Di Lalla | Summary: The Crab pulsar and its nebula are among the most studied astrophysical systems, and constitute one of the most promising environments where high energy processes and particle acceleration can be investigated. They are the […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Roger W. Romani, D. Kandel, Alexei V. Filippenko, Thomas G. Brink, WeiKang Zheng | Summary: We describe Keck-telescope spectrophotometry and imaging of the companion of the “black widow" pulsar PSR~J0952$-$0607, the fastest known spinning neutron star (NS) in the disk of the Milky Way. The companion […]
Kavli Affiliate: C. M. Ignarra | First 5 Authors: J. Aalbers, D. S. Akerib, C. W. Akerlof, A. K. Al Musalhi, F. Alder | Summary: The LUX-ZEPLIN (LZ) experiment is a dark matter detector centered on a dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility in Lead, South Dakota, USA. This […]
Kavli Affiliate: C. M. Ignarra | Summary:The LUX-ZEPLIN experiment is a dark matter detector centered on a dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility in Lead, South Dakota, USA. This Letter reports results from LUX-ZEPLIN’s first search for weakly interacting massive particles (WIMPs) with an exposure of 60~live days using […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Sebastian Baum, Michael A. Fedderke, Peter W. Graham, , | Summary: Dark compact objects ("clumps") transiting the Solar System exert accelerations on the test masses (TM) in a gravitational-wave (GW) detector. We reexamine the detectability of these clump transits in a variety of current and future […]
