Numerical integrator for highly oscillatory differential equations based on the Neumann series

Kavli Affiliate: Grzegorz Madejski | First 5 Authors: Rafał Perczyński, Grzegorz Madejski, , , | Summary: We propose a third-order numerical integrator based on the Neumann series and the Filon quadrature, designed mainly for highly oscillatory partial differential equations. The method can be applied to equations that exhibit small or moderate oscillations; however, counter-intuitively, large […]

Highly Significant Detection of X-Ray Polarization from the Brightest Accreting Neutron Star Sco X-1

Kavli Affiliate: Nicola Omodei | First 5 Authors: Fabio La Monaca, Alessandro Di Marco, Juri Poutanen, Matteo Bachetti, Sara E. Motta | Summary: The Imaging X-ray Polarimetry Explorer (IXPE) measured with high significance the X-ray polarization of the brightest Z-source Scorpius X-1, resulting in the nominal 2-8 keV energy band in a polarization degree of […]

Extragalactic Magnetism with SOFIA (SALSA Legacy Program). VII. A tomographic view of far infrared and radio polarimetric observations through MHD simulations of galaxies

Kavli Affiliate: Susan E. Clark | First 5 Authors: Sergio Martin-Alvarez, Enrique Lopez-Rodriguez, Tara Dacunha, Susan E. Clark, Alejandro S. Borlaff | Summary: The structure of magnetic fields in galaxies remains poorly constrained, despite the importance of magnetism in the evolution of galaxies. Radio synchrotron and far-infrared dust polarization (FIR) polarimetric observations are the best […]

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 […]

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, […]
