The substellar population in Corona Australis Open
Context . The substellar initial mass function (IMF) and the formation mechanisms of brown dwarfs (BDs) remain key open questions in star formation theory. A detailed census and characterization of the IMF in a large number of star-forming…

Citizen science illuminates the nature of city lights Open
The image of Earth at night from space, with its constellations of cities, has become iconic. However, our understanding of the source and scale of artificial light emissions is still in the dark, hampering urban environmental protection e…

EWOCS-III: JWST observations of the supermassive star cluster Westerlund 1 Open
The typically large distances, extinction, and crowding of Galactic supermassive star clusters have so far hampered the identification of their very low mass members, required to extend our understanding of star and planet formation, and e…

EWOCS-III: JWST observations of the supermassive star cluster Westerlund 1 Open
Context . The typically large distances, extinction, and crowding of Galactic supermassive star clusters (stellar clusters more massive than 10 4 M ⊙ ) have so far hampered the identification of their very low mass members, required to ext…

What’s in a Watt? Interpreting nightlights satellite data via citizen science observations Open
The image of Earth at Night from space has become iconic, but we are still in the dark when it comes to the question of to what extent different light source types contribute to city light emissions. Our team of citizen scientists used the…

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Westerlund 1 and 2 Open Clusters Survey Open
Context . With a mass exceeding several 10 4 M ⊙ and a rich and dense population of massive stars, supermassive young star clusters represent the most massive star-forming environment that is dominated by the feedback from massive stars an…

Nachtlichter App Open
The relationship between satellite based measurements of city radiance at night and the numbers and types of physical lights installed on the ground is not well understood. Here we present the “Nachtlichter app”, which was developed to ena…

Stochastic gravitational-wave background on large cosmological scales Open
Aim: To formulate a model capable of distinguishing astro-physical from primordial gravitational-wave signals. Methods: We used a biased tracer formalism valid on large cosmological scales to introduce modeling basics and con-nected black …
