A Stress Induced Source of Phonon Bursts and Quasiparticle Poisoning

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." Recently, a superconductor with one […]

2022 Upgrade and Improved Low Frequency Camera Sensitivity for CMB Observation at the South Pole

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 […]

Improved Polarization Calibration of the BICEP3 CMB Polarimeter at the South Pole

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: J. Cornelison, C. Vergès, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: The BICEP3 Polarimeter is a small aperture, refracting telescope, dedicated to the observation of the Cosmic Microwave Background (CMB) at 95GHz. It is designed to target degree angular scale polarization patterns, in particular […]

A measurement of the mean central optical depth of galaxy clusters via the pairwise kinematic Sunyaev-Zel’dovich effect with SPT-3G and DES

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: E. Schiappucci, F. Bianchini, M. Aguena, M. Archipley, L. Balkenhol | Summary: We infer the mean optical depth of a sample of optically-selected galaxy clusters from the Dark Energy Survey (DES) via the pairwise kinematic Sunyaev-Zel’dovich (kSZ) effect. The pairwise kSZ signal between pairs of clusters drawn […]

On the origin of radio-loudness in active galactic nuclei using far-infrared polarimetric observations

Kavli Affiliate: Roger Blandford | First 5 Authors: Enrique Lopez-Rodriguez, Makoto Kishimoto, Robert Antonucci, Mitchell C. Begelman, Noemie Globus | 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 […]

Jets, Disks and Winds from Spinning Black Holes: Nature or Nurture?

Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Noemie Globus, , , | Summary: A brief summary is given of an alternative interpretation of the Event Horizon Telescope observations of the massive black hole in the nucleus of the nearby galaxy M87. It is proposed that the flow is primarily powered by the […]
