PSR J0952-0607: The Fastest and Heaviest Known Galactic Neutron Star

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 […]

Moderate-Resolution $K$-Band Spectroscopy of the Substellar Companion VHS 1256 b

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 […]

Absolute Flux Calibrations for the Nancy Grace Roman Space Telescope Coronagraph Instrument

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 […]

Searching for Dark Clumps with Gravitational-Wave Detectors

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 […]
