SQM Ageing and Atmospheric Conditions: How Do They Affect the Long-Term Trend of Night Sky Brightness Measurements?
Sensors (Basel)
January 2025
European Southern Observatory, Santiago 7630000, Chile.
The most widely used radiance sensor for monitoring Night Sky Brightness (NSB) is the Sky Quality Meter (SQM), making its measurement stability fundamental. A method using the Sun as a calibrator was applied to analyse the quality of the measures recorded in the Veneto Region (Italy) and at La Silla (Chile). The analysis mainly revealed a tendency toward reductions in measured NSB due to both instrument ageing and atmospheric variations.

Near-surface O is a harmful atmospheric pollutant and a key component of urban photochemical pollution. The availability of satellite ozone concentration products is predominantly restricted to daytime, resulting in a lack of understanding of nighttime ozone pollution (e.g.

Article Synopsis
- The "dark age consistency ratio" is a proposed new observable for studying the 21 cm global signal during the universe's dark ages, aimed at testing models beyond the standard ΛCDM cosmological model.
- This ratio is based on the idea that the shape of the 21 cm signal's frequency response is largely unaffected by cosmological parameters in the ΛCDM framework, yielding a specific value that can help distinguish between models.
- The observable only requires brightness temperature measurements at a few frequency bands, making it feasible to evaluate cosmological theories even with limited data from upcoming lunar telescope missions.
Comparative SERS Activity of Homometallic and Bimetallic Core-Satellite Assemblies.

The fabrication of core-satellite (CS) assemblies offers a versatile strategy for tailoring the optical properties of plasmonic nanomaterials. In addition to key factors like size, shape, and spatial arrangement of individual components, the combination of plasmonic units with different compositions (e.g.

A monolayer semiconductor transferred on nanopillar arrays provides site-controlled, on-chip single photon emission, which is a scalable light source platform for quantum technologies. However, the brightness of these emitters reported to date often falls short of the perceived requirement for such applications. Also, the single photon purity usually degrades as the brightness increases.
