Infrared fibres in astronomical instrumentation [PDF]
, 1995 For several years multi-object spectroscopy systems have been available for carrying out survey work in the visible region, but until very recently there has not been a system for the near infrared region.

High-contrast Imaging with Fizeau Interferometry: The Case of Altair [PDF]
, 2022 The Large Binocular Telescope (LBT) has two 8.4 m primary mirrors that produce beams that can be combined coherently in a "Fizeau"interferometric mode. In principle, the Fizeau point-spread function (PSF) enables the probing of structure at a resolution ...

Advanced Functional Materials, EarlyView.ABSTRACT Next‐generation implantable neural‐interfacing devices are increasingly constrained by the coupled demands of electrode miniaturization, electrochemical performance, and implantation infection risk. Femtosecond laser–based hierarchical surface restructuring (HSR) technology has emerged as a scalable, manufacturing‐compatible platform for ...

Cone Effect in Astronomical Adaptive Optics System Investigated by a Pure Numerical Simulation [PDF]
, 2005 It is well-known that cone effect or focus anisoplanatism is produced by the limited distance of a laser guide star (LGS) which is created within the Earth atmosphere and consequently located at a finite distance from the observer.

Turbulence characterisation for Astronomical Observatories [PDF]
, 2012 Atmospheric turbulence has two effects in astronomy; (i) the broadening of the point spread function due to phase fluctuations limiting the resolution of imaging and (ii) producing intensity fluctuations known as scintillation.

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 ...

Conception and development of an adaptive optics testbed for free-space optical communication [PDF]
, 2009 Optical free space communications are an efficient approach to transmit high data-rates with small antennas and low power consumption over large distances. Possible scenarios are links between satellites, up- and down-links from and to ground stations as

Advanced Materials, EarlyView.ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...
