Solar Radiation Affects Bird Distributions but Not Elevational Shifts in European Mountains Open
Aim Climate change is driving species towards higher elevations. While local shifts in elevation are well documented, patterns across entire mountain regions are less understood. On a local scale, abiotic factors, such as topography and so…

Dust sub-millimetre emission in green valley galaxies Open
Context. Green valley (GV) galaxies are objects defined on a colour–magnitude diagram, or a colour–mass diagram, as being associated with a transition from a star-forming to a quiescent state (quenching), or vice versa (rejuvenation). Aims…

Implementation of Gaussian quadrature in Python program for grillages with curved elements Open
This paper demonstrates the development of a Python program for linear-elastic structural analysis of grillages featuring circumferential arc-shaped and regular straight elements subjected to concentrated and distributed loads. The algorit…

Impact of vegetation albedo on the habitability of Earth-like exoplanets Open
Vegetation can modify the planetary surface albedo via the Charney mechanism, as plants are usually darker than the bare surface of the continents. We updated ESTM (Earth-like surface temperature model) to incorporate the presence, distrib…

Contribution of very massive stars to the sulfur abundance in star-forming galaxies: Role of pair-instability supernovae Open
Context. Recent work presented increasing evidence of high non-constant S/O abundance ratios observed in star-forming metal-poor galaxies that deviated from the constant canonical S/O across a wide range of O/H abundances. Similar peculiar…

Impact of very massive stars on the chemical evolution of extremely metal-poor galaxies Open
Context. In recent observations of extremely metal-poor, low-mass, starburst galaxies, almost solar Fe/O ratios are reported, despite N/O ratios consistent with the low metallicity. Aims. We aim to investigate if the peculiar Fe/O ratios c…

The effects of the initial mass function on Galactic chemical enrichment Open
Context. We have been seeing mounting evidence that the stellar initial mass function (IMF) might extend far beyond the canonical M i ∼ 100 M ⊙ limit, but the impact of such a hypothesis on the chemical enrichment of galaxies is yet to be …
