Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Cyndia Yu, Zeeshan Ahmed, Jake A. Connors, J. Mitch D’Ewart, Bradley Dober | Summary: The microwave SQUID multiplexer (umux) has enabled higher bandwidth or higher channel counts across a wide range of experiments in particle physics, astronomy, and spectroscopy. The large multiplexing factor coupled with recent commercial […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Jacco Vink, Dmitry Prokhorov, Riccardo Ferrazzoli, Patrick Slane, Ping Zhou | Summary: We report on a 5$sigma$ detection of polarized 3-6 keV X-ray emission from the supernova remnant Cassiopeia A with the Imaging X-ray Polarimetry Explorer (IXPE) mission. The overall polarization degree of 1.8 $pm$ 0.3% is […]
Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Michael Kopp, Tom Abel, , | Summary: We investigate the timescale on which quantum corrections alter the predictions of classical field theory for scalar field dark matter. This is accomplished by including second order terms in the evolution proportional to the covariance of the field […]
Kavli Affiliate: James Chiang | First 5 Authors: Massimo Bartoletti, James Chiang, Tommi Junttila, Alberto Lluch Lafuente, Massimiliano Mirelli | Summary: Decentralised Finance (DeFi) applications constitute an entire financial ecosystem deployed on blockchains. Such applications are based on complex protocols and incentive mechanisms whose financial safety is hard to determine. Besides, their adoption is rapidly […]

Kavli Affiliate: Steven W. Allen | First 5 Authors: Jack Sayers, Adam B. Mantz, Elena Rasia, Steven W. Allen, Weiguang Cui | Summary: We have combined X-ray observations from Chandra with Sunyaev-Zel’dovich (SZ) effect data from Planck and Bolocam to measure intra-cluster medium pressure profiles from 0.03R$_{500}$ $le$ R $le$ 5R$_{500}$ for a sample of […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Noah Glennon, Ethan O. Nadler, Nathan Musoke, Arka Banerjee, Chanda Prescod-Weinstein | Summary: Ultralight axions (ULAs) are promising dark matter candidates that can have a distinct impact on the formation and evolution of structure on nonlinear scales relative to the cold, collisionless dark matter (CDM) paradigm. […]
Kavli Affiliate: Kevin Reil | First 5 Authors: Joseph Harry Silber, Parker Fagrelius, Kevin Fanning, Michael Schubnell, Jessica Nicole Aguilar | Summary: A system of 5,020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically re-target their optical fibers every 10 – 20 minutes, each […]
