A soft x-ray polarimeter designed for broadband x-ray telescopes [PDF]

SPIE Proceedings, 2007
A novel approach for measuring linear X-ray polarization over a broad-band using conventional imaging optics and cameras is described. A new type of high efficiency grating, called the critical angle transmission grating is used to disperse soft X-rays radially from the telescope axis.

Case Study of a Fly's Eye Homogenizer for the Calibration Illumination of Integral Field Units

Astronomische Nachrichten, EarlyView.
ABSTRACT Integral‐field unit spectrographs require a homogeneous calibration illumination of the field of view for proper flat and wavelength calibration (e.g., BlueMUSE which is currently under development for the VLT). This article presents the adaptation of a fly's eye homogenizer, frequently used in laser applications, to this task in astronomical ...

The absence of women's scientific contributions in core UK pre‐university science qualifications

British Educational Research Journal, EarlyView.
Abstract Despite their groundbreaking contributions to our understanding of the natural world and the universe, women's roles in biology, chemistry, physics, astronomy, environmental science and geology remain largely absent from standard educational specifications in the United Kingdom (UK), particularly at Key Stage 4 (KS4) and Key Stage 5 (KS5), or ...

Trends and Future Directions in Organic Chemistry for Drug Discovery

Chemistry – A European Journal, EarlyView.
Organic synthesis is being reshaped by the convergence of catalytic innovation, automation, artificial intelligence, and emerging therapeutic modalities. Late‐stage functionalization, photoredox and electrochemical methods, biocatalysis, flow chemistry, DELs, and proximity‐based drugs are examined as components of closed‐loop discovery.
