The Effelsberg Direct Digitisation radio astronomy back-end framework

Astronomy & Astrophysics
Context. Modern digital radio astronomy receivers produce increasingly wide-bandwidth, high bit-rate data streams that necessitate the development of flexible, scalable, and maintainable back-end processing and recording systems.

Accelerated Discovery of Topological Spin Phase Diagrams in CrSBr Magnets Via High‐Throughput Optimization

Advanced Functional Materials, EarlyView.
Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

Current‐Driven Chirality Detection of Magnetic Textures in Cylindrical Nanowires

Advanced Functional Materials, EarlyView.
Current‐assisted anisotropic magnetoresistance measurements in individual Ni/Au cylindrical nanowires enable detection of vortex chirality near Au segments and selective magnetic reversal in defined wire sections at magnetic fields lower than the propagation field. This approach provides a simple, cost‐effective, and non‐invasive method for probing and

The 1948 solar eclipse and the genesis of radio astronomy in Victoria [PDF]

, 2004
In the early years of radio astronomy, solar eclipses played a critical role in establishing the sources of solar radio emission. During the half decade from 1945, Australia emerged as a leading nation in radio astronomy, with most of the observations ...

Switching Superconductivity with Uniaxial Strain in a high‐Tc${\rm T}_{c}$ Cuprate Superconductor

Advanced Functional Materials, EarlyView.
Uniaxial strain is demonstrated as a new scheme for a superconductivity switch. Exploiting the large strain‐induced Tc shift in a cuprate superconductor enables robust switching between superconducting and normal states over 100 cycles with only 0.1% strain.

A Design Study of 100GHz Band Local Oscillator System by Using Yig Oscillator [PDF]

Journal of Astronomy and Space Sciences, 2003
In this paper, we make a design study for a local oscillator system of the 100 GHz band cosmic radio receiving system. We use the YIG oscillator with digital driver which is the main oscillator. This oscillator has a good frequency and phase stability at

Evidence for Itinerant Ferromagnetic Flat Bands Producing Large Transverse Responses

Advanced Materials, EarlyView.
Itinerant ferromagnetic flat bands are demonstrated in GdCo5 with a high Curie temperature of 940K, a stacked honeycomb–kagome lattice, through angle‐resolved photoemission spectroscopy and magneto‐thermoelectric measurements. These topological flat bands generate large Berry curvaturte, producing gigantic anomalous Nernst effect with record‐high ...
