Fitting pseudo-S${rm acute{e}}$rsic(Spergel) light profiles to galaxies in interferometric data: the excellence of the $uv$-plane

Posted by dbos Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Qing-Hua Tan, Emanuele Daddi, Victor de Souza Magalhães, Carlos Gómez-Guijarro, Jérôme Pety | Summary: Modern (sub)millimeter interferometers, such as ALMA and NOEMA, offer high angular resolution and unprecedented sensitivity. This provides the possibility to characterize the morphology of the gas and dust in distant galaxies. To […]

Kinematic Flow and the Emergence of Time

Posted by Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Nima Arkani-Hamed, Daniel Baumann, Aaron Hillman, Austin Joyce, Hayden Lee | Summary: Perhaps the most basic question we can ask about cosmological correlations is how their strength changes as we smoothly vary kinematic parameters. The answer is encoded in differential equations that govern this evolution in kinematic […]

Differential Equations for Cosmological Correlators

Posted by Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Nima Arkani-Hamed, Daniel Baumann, Aaron Hillman, Austin Joyce, Hayden Lee | Summary: Cosmological fluctuations retain a memory of the physics that generated them in their spatial correlations. The strength of correlations varies smoothly as a function of external kinematics, which is encoded in differential equations satisfied by […]

Hiding Functions within Functions: Steganography by Implicit Neural Representations

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Peng Luo, Yan Ke, , | Summary: Deep steganography utilizes the powerful capabilities of deep neural networks to embed and extract messages, but its reliance on an additional message extractor limits its practical use due to the added suspicion it can raise from steganalyzers. To […]

PWN-powered Galactic Center X-ray filament G0.13-0.11: Proof of the synchrotron nature by IXPE

Posted by dbos MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Eugene Churazov, Ildar Khabibullin, Thibault Barnouin, Niccolò Bucciantini, Enrico Costa | Summary: We report the discovery of X-ray polarization from the X-ray-bright thread/filament G0.13-0.11 in the Galactic Center region. This filament features a bright hard X-ray source, most plausibly a Pulsar Wind Nebula (PWN), and an […]
