XIPE: the X-ray Imaging Polarimetry Explorer [PDF]

open access: yes, 2013
X-ray polarimetry, sometimes alone, and sometimes coupled to spectral and temporal variability measurements and to imaging, allows a wealth of physical phenomena in astrophysics to be studied.

UAVSAR Observations of InSAR Polarimetric Phase Diversity: Implications for NISAR Ionospheric Phase Estimation

open access: yesEarth and Space Science, 2021
The NASA‐ISRO Synthetic Aperture Radar (NISAR) is a repeat‐pass radar mission that will acquire fully polarimetric SAR data in an innovative acquisition mode known as quasi‐quad pol (QQP).

On the spin modulated circular polarization from the intermediate polars NY Lup and IGRJ1509-6649

open access: yes, 2011
We report on high time resolution, high signal/noise, photo-polarimetry of the intermediate polars NY Lup and IGRJ1509-6649. Our observations confirm the detection and colour dependence of circular polarization from NY Lup and additionally show a clear ...

Biomacromolecular stereostructure mediates mode hybridization in chiral plasmonic nanostructures [PDF]

open access: yes, 2016
The refractive index sensitivity of plasmonic fields has been exploited for over 20 years in analytical technologies. While this sensitivity can be used to achieve attomole detection levels, they are in essence binary measurements that sense the presence/

Material Modification of Borofloat 33 During Scanning‐Based Microforming Using Femtosecond Laser Pulses

open access: yesAdvanced Optical Materials, Volume 14, Issue 14, 10 April 2026.
Possibilities for ablation‐free microforming of borosilicate glass using ultrashort laser pulses are presented. Depending on the laser parameters and scanning strategy, surface structures with profile heights of up to 20 µm could be produced. The work provides a comprehensive experimental and analytical characterization of the microforming process ...

Discovery of spin modulated circular polarization from IGR J17014-4306, the remnant of Nova Scorpii 1437 A.D

open access: yes, 2017
Polarimetry of IGR J1401-4306, a long period (12.7 hours), eclipsing intermediate polar and remnant of Nova Scorpii 1437 A.D., reveals periodic variations of optical circular polarization, confirming the system as the longest period eclipsing ...

Ks- and Lp-band polarimetry on stellar and bow-shock sources in the Galactic center [PDF]

open access: yes, 2013
Infrared observations of the Galactic center (GC) provide a unique opportunity to study stellar and bow-shock polarization effects in a dusty environment. The goals of this work are to present new Ks- and Lp-band polarimetry on an unprecedented number of

Engineering Asymmetry: How Chirality Boosts Catalysis, Spin Selectivity, and Light–Matter Interactions

open access: yesChemPhotoChem, Volume 10, Issue 4, April 2026.
This review connects chiroptical spectroscopy, asymmetric catalysis, and spintronics, revealing how chirality influences the interactions of matter with light, charge, and spin. Across diverse systems, remarkable chiroptical effects emerge, showing among others that high efficiencies can arise without absolute enantiopurity, and that functionality is ...

Inverse Design for Robust Inference in Integrated Computational Spectrometry

open access: yesNanophotonics, Volume 15, Issue 7, 13 April 2026.
This work demonstrates that integrated computational spectrometers can be inverse‐designed to substantially improve noise tolerance without relying on training data or specific inference algorithms, offering an alternative to conventional end‐to‐end co‐design strategies.
