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: 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: 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 […]
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 […]
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 […]
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 […]
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$-$0607, the fastest known spinning neutron star (NS) in the disk of the Milky Way. The companion […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Kielan K. W. Hoch, Quinn M. Konopacky, Travis S. Barman, Christopher A. Theissen, Laci Brock | Summary: We present moderate-resolution ($Rsim4000$) $K$ band spectra of the planetary-mass companion VHS 1256 b. The data were taken with the OSIRIS integral field spectrograph at the W.M. Keck Observatory. The […]
