Crosstalk effects in microwave SQUID multiplexed TES bolometer readout

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: John C. Groh, Zeeshan Ahmed, Shawn W. Henderson, Johannes Hubmayr, John A. B. Mates | Summary: Transition-edge sensor (TES) bolometers are broadly used for background-limited astrophysical measurements from the far-infrared to mm-waves. Many planned future instruments require increasingly large detector arrays, but their scalability is limited by […]

Tracking the X-ray Polarization of the Black Hole Transient Swift J1727.8-1613 during a State Transition

Kavli Affiliate: Roger W. Romani | First 5 Authors: Adam Ingram, Niek Bollemeijer, Alexandra Veledina, Michal Dovciak, Juri Poutanen | Summary: We report on an observational campaign on the bright black hole X-ray binary Swift J1727.8$-$1613 centered around five observations by the Imaging X-ray Polarimetry Explorer (IXPE). These observations track for the first time the […]

End-to-End Modeling of the TDM Readout System for CMB-S4

Kavli Affiliate: Kent Irwin | First 5 Authors: David C. Goldfinger, Zeeshan Ahmed, Darcy R. Barron, W. Bertrand Doriese, Malcolm Durkin | Summary: The CMB-S4 experiment is developing next-generation ground-based microwave telescopes to observe the Cosmic Microwave Background with unprecedented sensitivity. This will require an order of magnitude increase in the 100 mK detector count, […]

On Why the 10-TeV Cosmic Ray Bump Originates in the Local Interstellar Medium

Kavli Affiliate: Igor Moskalenko | First 5 Authors: Mikhail Malkov, Patrick Diamond, Mingyun Cao, Igor Moskalenko, | Summary: Recent measurements of primary and secondary CR spectra, their arrival directions, and our improved knowledge of the magnetic field geometry around the heliosphere allow us to set a bound on the distance beyond which a puzzling 10-TeV […]
