A dew detector for use with astronomical telescopes [PDF]
Publications of the Astronomical Society of the Pacific, 1987 The design of a dew detector for use on astronomical telescopes is described. The sensing element for the detector is a piece of printed-circuit board etched with a grid pattern of metallic and nonmetallic areas. The sensor grid pattern is produced on the circuit board by photoetching from a positive contact-printing mask.

Advanced Materials Technologies, EarlyView.The opto‐electronic response of polycrystalline (PEA)2PbBr4 thin films is investigated by correlating macroscopic photodetector performance with nanoscale mapping techniques. Grain boundary density is systematically tuned through crystallization control and linked to device responsivity.

Detecting fluorescent dark matter with X-ray lasers
European Physical Journal C: Particles and Fields, 2018 Fluorescent dark matter has been suggested as a possible explanation of both the 3.5 keV excess in the diffuse emission of the Perseus Cluster and of the deficit at the same energy in the central active galaxy within that cluster, NGC 1275.

Lossless Astronomical Image Compression and the Effects of Noise
, 2009 We compare a variety of lossless image compression methods on a large sample of astronomical images and show how the compression ratios and speeds of the algorithms are affected by the amount of noise in the images.

Beam-combining superconducting detector for submillimetre-wave astronomical interferometry
Electronics Letters, 2003 The feasibility of making single-chip, superconducting detectors for submillimetre-wave astronomical inteferometry is demonstrated. An experimental device based on back-to-back corrugated horns, and back-to-back finline transitions, was fabricated.
