Advanced LIGO detector performance in the fourth observing run
E. Capote, W. Jia, N. Aritomi +193
On May 24th, 2023, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), joined by the Advanced Virgo and KAGRA detectors, began the fourth observing run for a t…
Temporal Changes in the Infrared Spectra of Magellanic Carbon Stars
G. C. Sloan, K. E. Kraemer, B. Aringer +9
The Medium-Resolution Spectrometer on the Mid-Infrared Instrument on JWST obtained spectra of three carbon stars in the Large Magellanic Cloud. Two of the spectra differ significan…
Measuring photon correlation using imperfect detectors
Rachel N. Clark, Sam G. Bishop, Joseph K. Cannon +4
Single-photon detectors are ``blind" after the detection of a photon, and thereafter display a characteristic recovery in efficiency, during which the number of undetected photons…
Artificial Intelligence for Collective Intelligence: A National-Scale Research Strategy
Seth Bullock, Nirav Ajmeri, Mike Batty +15
Advances in artificial intelligence (AI) have great potential to help address societal challenges that are both collective in nature and present at national or trans-national scale…
Development of Underactuated Geometric Compliant (UGC) Module with Variable Radial for Robotic Applications
Mark Krysov, Seyed Amir Tafrishi
This paper introduces a novel underactuated geometric compliant (UGC) robot and investigates the behaviors of underactuated compliant modules with variable radial stiffness, aiming…
Limits to dynamic range in GHz-THz single-dish planetary spectra
J S Greaves
When bright solar-system objects are observed by GHz-THz regime telescopes, off-axis signals bounce around locally and re-enter the signal path with a time delay, causing sinusoida…
Development of an MKID frequency-to-pixel LED mapper for SPT-3G+
E. S. Martsen, P. S. Barry, B. A. Benson +5
SPT-3G+ is the next-generation camera for the South Pole Telescope (SPT). SPT is designed to measure the cosmic microwave background (CMB) and the mm/sub-mm sky. The planned focal…
