Orthogonal Dendritic Intrinsic Networks: An Architecture for Significance-Ordered, Orthogonal Latent Spaces

Posted by klaurent July 6, 2026July 20, 2026Stanford

Kavli Affiliate: Zeeshan Ahmed | Summary:Principal Component Analysis or PCA-like properties (orthogonality, variance ranking) are seldom realized in deep autoencoder architectures. In this work, we present ODIN (Orthogonal Dendritic Intrinsic Network), a novel autoencoder architecture that recovers PCA-like latent structure in a fully non-linear regime. By incorporating a set of geometric constraints directly into the […]

Verifiable blind quantum computing: Comparative analysis and design considerations for client architectures

Posted by klaurent July 6, 2026July 20, 2026Delft

Kavli Affiliate: Stephanie Wehner | Summary:Blind quantum computing (BQC) allows a client to delegate quantum computations to a remote server without revealing the input, computation, or output. In addition to being blind, the client can sometimes also verify that the server has performed their instructions correctly, a property known as verifiability. A key part of […]

BlackTHUNDER Reveals a Massive Filament around a Compact AGN at $zsimeq5.23$

Posted by klaurent July 6, 2026July 20, 2026Cambridge

Kavli Affiliate: Roberto Maiolino | Summary:Despite the growing number of compact active galactic nuclei (AGN) at $z>4$ discovered by JWST, their formation and evolution remain poorly understood. This paper investigates the large-scale environment of GN-77652, a compact AGN at $z=5.229$ observed as part of the JWST NIRSpec IFU Large Program BlackTHUNDER and complemented by deep […]

Globular cluster abundance patterns inherited from giant molecular clouds

Posted by klaurent July 6, 2026July 20, 2026Cambridge

Kavli Affiliate: Roberto Maiolino | Summary:Globular clusters exhibit large star-to-star variations and anticorrelations in their light element abundances that are commonly interpreted in terms of in-cluster self-enrichment, in which ejecta from early-forming cluster stars pollute the gas from which later stars form over millions of years. Yet proposed self-enrichment scenarios suffer from a severe mass-budget […]

A Novel Implementation of Self-Interacting Dark Matter in AREPO

Posted by klaurent July 6, 2026July 20, 2026MIT

Kavli Affiliate: Mark Vogelsberger | Summary:Self-interacting dark matter (SIDM) influences halo structure through collisional heat transport and may solve several small-scale puzzles in structure formation. SIDM creates thermalized cores in low-mass haloes, which may account for the observed cored dwarf galaxies. During late-time gravothermal core collapse, SIDM can produce dense low-mass DM haloes and substructures […]

The emergence of X-ray emission lines during relativistic radio-jet formation in the changing-look active galactic nucleus 1ES 1927+654

Posted by klaurent July 6, 2026July 20, 2026MIT

Kavli Affiliate: Erin Kara | Summary:We present results from a comprehensive multi-wavelength monitoring campaign of the changing-look active galactic nucleus 1ES 1927+654 during the onset and evolution of a radio jet (May 2022-August 2025). Using observations from XMM-Newton, Swift, TNG, ZTF, VLA, and VLBA, we characterize the spectral evolution of the source. Soft X-ray emission […]

Comparing gravitational wave background predictions from cosmological simulations to pulsar timing observations

Posted by klaurent July 6, 2026July 20, 2026Cambridge

Kavli Affiliate: Debora Sijacki | Summary:The recent detection of a gravitational wave background (GWB) by pulsar timing arrays (PTAs) may represent the first evidence of gravitational waves from merging supermassive black hole binaries, opening a new window on the low-frequency end of the gravitational wave spectrum. These inspiralling binaries are expected to dominate the signal, […]

In-Band Scattering and Absorption of Infrared Blocking Foam Filters for Millimeter-wave Cameras

Posted by klaurent July 6, 2026July 20, 2026Chicago

Kavli Affiliate: Jeffrey McMahon | Summary:Expanded closed-cell polymer foams are widely used as thermal infrared (IR) blocking filters in millimeter-wave cameras, particularly for Cosmic Microwave Background observations. Precise knowledge of their millimeter-wave properties is essential for optimizing sensitivity. We present broadband (150 GHz – 2 THz) transmittance spectroscopy of Styroace-II and several Zotefoam filters, fitting […]

On the $mathrmIn_xGa_1-xAs$ channel noise in InP HEMTs from 4 K to 300 K

Posted by klaurent July 6, 2026Caltech

Kavli Affiliate: Austin Minnich | Summary:The InP high-electron-mobility transistor (HEMT) is indispensable for low-noise amplifiers (LNAs) in radio astronomy and quantum computing. The composition of the $mathrmIn_xGa_1-xAs$ channel in InP HEMT is known to influence the LNA noise performance. However, the various physical mechanisms responsible for noise generation are not fully characterized and understood. Here, […]
