Kavli Affiliate: Nicola Omodei | First 5 Authors: Jiří Svoboda, Michal Dovčiak, James F. Steiner, Fabio Muleri, Adam Ingram | Summary: X-ray polarization is a powerful tool to investigate the geometry of accreting material around black holes, allowing independent measurements of the black hole spin and orientation of the innermost parts of the accretion disk. […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Doyeon Avery Kim, Susan E Clark, Mary E Putman, Larry Li, | Summary: We characterize the kinematic and magnetic properties of HI filaments located in a high Galactic latitude region ($165^circ < alpha < 195^circ$ and $12^circ < delta < 24^circ$). We extract three-dimensional filamentary structures […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Isabella A. Gerrard, Christoph Federrath, Nickolas M. Pingel, Naomi M. McClure-Griffiths, Antoine Marchal | Summary: Turbulence plays a crucial role in shaping the structure of the interstellar medium. The ratio of the three-dimensional density contrast ($sigma_{rho/rho_0}$) to the turbulent sonic Mach number ($mathcal{M}$) of an isothermal, […]
Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Paul Simeon, Noémie Globus, Payel Mukhopadhyay, Enrico Peretti | Summary: The hypothesis that the entire cosmic ray spectrum, from $lesssim1,{rm GeV}$ to $gtrsim100,{rm EeV}$ energy, can be accounted for by diffusive shock acceleration on increasingly large scales is critically examined. Specifically, it is conjectured that […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Muhammad Salman Bashir, Qasim Zeeshan Ahmed, Mohamed-Slim Alouini, , | Summary: The selection of an optimal photodetector area is closely linked to the attainment of higher data rates in optical wireless communication receivers. If the photodetector area is too large, the channel capacity degrades due to lower […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Vanessa P. Bailey, Eduardo Bendek, Brian Monacelli, Caleb Baker, Gasia Bedrosian | Summary: The Nancy Grace Roman Space Telescope Coronagraph Instrument is a critical technology demonstrator for NASA’s Habitable Worlds Observatory. With a predicted visible-light flux ratio detection limit of 1E-8 or better, it will be capable […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Chao Liu, Zeeshan Ahmed, Shawn W. Henderson, Ryan Herbst, Larry Ruckman | Summary: From generation to generation, the maximum RF frequency and sampling rate of the integrated data converters in RF system-on-chip (RFSoC) family devices from Xilinx increases significantly. With the integrated digital mixers and up and […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Sebastian Baum, Zachary Bogorad, Peter W. Graham, , | Summary: Gravitational Waves (GWs) have been detected in the $sim 100$ Hz and nHz bands, but most of the gravitational spectrum remains unobserved. A variety of detector concepts have been proposed to expand the range of observable […]

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Arpita Vats, Zhe Liu, Peng Su, Debjyoti Paul, Yingyi Ma | Summary: Model adaptation is crucial to handle the discrepancy between proxy training data and actual users data received. To effectively perform adaptation, textual data of users is typically stored on servers or their local devices, where […]
