The Cygnus-X complex is the most powerful massive star-forming region at less than 2 kpc from us. The region has been largely studied along the last decades, but there has been no extensive and homogeneous spectroscopic survey on its stellar population despite its importance to our limited knowledge of star formation and evolution of star-forming

Astronomic instrumentation requires working at cryogenic temperatures and a high stability. It is crucial to understand the properties of materials and contacts among components within the cryostat to be able to achieve the thermal goals in astronomical applications. To enhance instrument cold structure designs, there's a growing need to perform

The aim of this paper is to improve our understanding of the heating mechanisms of the solar chromosphere via realistic three-dimensional modeling of solar magneto-convection, considering the fact that solar plasma contains a significant fraction of neutral gas. To that end, we performed simulations of the same physical volume of the Sun, namely 5

Aims. We aim to study the behaviour of Cl abundance and its ratios with respect to O, S, and Ar abundances in a sample of more than 200 spectra of Galactic and extragalactic H II regions and star-forming galaxies (SFGs) of the local Universe. Methods. We used the DEep Spectra of Ionised REgions Database (DESIRED) Extended project (DESIRED-E) that

In recent years, gravitational waves (GWs) have been detected from various sources, including black hole (BH) and neutron star (NS) mergers, posing new challenges to our understanding of massive stellar evolution. Although numerous population synthesis models have been presented to explain these events, their results depend on many parameters

The formation and migration history of a planet is expected to be imprinted in its atmosphere, in particular its carbon-to-oxygen (C/O) ratio and metallicity. The BOWIE-ALIGN (Bristol, Oxford, Warwick, Imperial, Exeter – A spectral Light Investigation into gas Giant origiNs) programme is performing a comparative study of JWST spectra of four
