Backlighting the Cosmic Web with Fast Radio Bursts: An Anthology of Dispersion Measure Cross-Correlations with Large-Scale Structure and Baryon Tracers

Posted by klaurent Stanford

Kavli Affiliate: W. L. Kimmy Wu | Summary:Fast Radio Bursts (FRBs) probe baryons permeating the cosmic web through their dispersion measures (DMs), which encode the integrated electron density along cosmological sightlines. Using 3,455 unique FRB sources from CHIME/FRB with $sim 15$ arcmin localizations, we present an anthology of DM correlations with tracers of large-scale structure […]

The Effects of Complex Accretion Disk Geometry on Broadened Iron K$α$ Lines

Posted by klaurent Stanford

Kavli Affiliate: Daniel R. Wilkins | Summary:X-rays are emitted from the corona above the orbiting matter of the accretion disk and travel either directly to us or illuminate the disk. This illumination of the inner disk is enhanced by gravitational light bending, which focuses the rays towards the black hole and therefore towards the inner […]

CuRast: Cuda-Based Software Rasterization for Billions of Triangles

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | Summary:Previous work shows that small triangles can be rasterized efficiently with compute shaders. Building on this insight, we explore how far this can be pushed for massive triangle datasets without the need to construct acceleration structures in advance. Method: A 3-stage rasterization pipeline first rasterizes small triangles directly in stage […]

Tailoring Germanium Heterostructures for Quantum Devices with Machine Learning

Posted by klaurent Delft

Kavli Affiliate: Giordano Scappucci | Summary:Germanium (Ge) quantum wells are emerging as versatile platforms for quantum devices, supporting high-quality spin qubits and integration with superconducting leads. These applications benefit from strong intrinsic spin-orbit interaction (SOI), enabling efficient electrical control and engineering of spin degrees of freedom. The most advanced Ge/SiGe heterostructures to date, based on […]
