Effects of the COVID-19 Lockdown on Urban Light Emissions: Ground and Satellite Comparison
‘Lockdown’ periods in response to COVID-19 have provided a unique opportunity to study the impacts of economic activity on environmental pollution (e.g., NO2, aerosols, noise, light).

Space debris contributions to night sky brightness
Aims. We quantify the uncertainty in space debris contributions to night sky brightness by comparing predictions from two major debris environment models and assessing the resulting signal-to-noise degradation for ground-based astronomical observations ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Anthropogenic disruption of the night sky darkness in urban and rural areas [PDF]
The growing emissions of artificial light to the atmosphere are producing, among other effects, a significant increase of the night sky brightness (NSB) above its expected natural values. A permanent sensor network has been deployed in Galicia (northwest

Comparative Analysis of Metal Preloading Technologies in Batteries and Capacitors
Metal preloading strategies play an important role in efficient batteries and hybrid capacitors to compensate for the consumed metals at the first discharge. This article reviews recent progress in preloading technologies in lithium‐ion and other metal‐ion systems.

Aftasten/Tantear: A sensorial, coalitional wayfinding among Muslim runners
Abstract Muslim recreational runners in Muslim‐minority settings that take up running as their preferred form of leisure indicate that they feel they have to navigate a sense of exclusion when running outdoors. This article explores the process of exploration and sensing in public, represented by the Dutch verb aftasten, to investigate the way Muslim ...

Operating in perpetual motion? Coping with the dark side of global boundary spanning
Abstract Research Summary This paper explores how individuals experience and cope with the demands of global boundary spanning in multinational enterprises (MNEs). We foreground temporary colocation as a modality through which mobile global boundary spanners repeatedly traverse multiple boundaries, triggering intense demands with adverse consequences ...
