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 […]
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: Bruce Macintosh | First 5 Authors: Lindsey Payne, Robert T. Zellem, Marie Ygouf, Bruce Macintosh, | Summary: The Nancy Grace Roman Space Telescope’s (Roman) Coronagraph Instrument is a technology demonstration equipped to achieve flux contrast levels of up to 10$^{-9}$. This precision depends upon the quality of observations and their resultant on-sky corrections […]
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 […]
