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 […]

Kavli Affiliate: Roger Blandford | First 5 Authors: Richard Anantua, Angelo Ricarte, George Wong, Razieh Emami, Roger Blandford | Summary: Horizon-scale observations of the jetted active galactic nucleus M87 are compared with simulations spanning a broad range of dissipation mechanisms and plasma content in three-dimensional general relativistic flows around spinning black holes. Observations of synchrotron […]

Kavli Affiliate: Nicola Omodei | First 5 Authors: Lorenzo Scotton, Frédéric Piron, Nicola Omodei, Niccolò Di Lalla, Elisabetta Bissaldi | Summary: GRB 220101A is the most distant gamma-ray burst detected by the Fermi-LAT to date, at a redshift z = 4.618. It is also a very energetic event, with an equivalent isotropic energy of $3.6times10^{54}$ […]
