Near‐Infrared Polarimetric Imaging With Nonlinear Flat‐Optics
Laser &Photonics Reviews, EarlyView.ABSTRACT A compact and broadband polarimetric imaging platform is presented, based on second‐harmonic generation (SHG) in nonlinear flat‐optics. The system employs periodic all‐dielectric AlGaAs gratings to induce polarization‐dependent SH emission, enabling pixel by pixel direct retrieval of the full Stokes vector from an input intensity distribution ...

Journal of Field Robotics, EarlyView.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

A study of extended red emission in reflection nebulae [PDF]
, 1994 In the first part of this thesis spectroscopic observations of the Red Rectangle nebula are presented. A link is made between the most prominent unique emission line features, which are superimposed on the broad emission spectrum of the Red Rectangle ...

The far-infrared-radio correlation in MS0451-03 [PDF]
, 2015 We present a multiwavelength analysis of star-forming galaxies in the massive cluster MS0451.6-0305 at z ˜ 0.54 to shed new light on the evolution of the far-infrared-radio relationship in distant rich clusters.

Small, EarlyView.Ammonium halide salts serve as inorganic modifiers that lower the melting and glass transition temperatures of zeolitic imidazolate frameworks, enabling centimeter‐scale hybrid glasses and melt processing of otherwise unmeltable ZIF‐8. In situ imaging and pair distribution function analysis reveal salt infiltration, Zn─N bond disruption, and Zn–halide ...

Far-infrared Luminosity Bursts Trace Mass Accretion onto Protostars
The Astronomical JournalEvidence abounds that young stellar objects undergo luminous bursts of intense accretion that are short compared to the time it takes to form a star. It remains unclear how much these events contribute to the main-sequence masses of the stars.
