Context. The use of 3D hydrodynamical simulations of stellar surface convection for model atmospheres is computationally expensive. Although these models have been available for quite some time, their use is limited because of the lack of extensive grids of simulations and associated spectra. Aims: Our goal is to provide a method to interpolate

The leading method for the determination of relevant stellar population parameters of unresolved extragalactic Globular Clusters is through the study of their integrated spectroscopy, where Balmer line-strength indices are considered to be age sensitive. Previously, a splitting in the highly optimized spectral line-strength index H β o was observed

Between September 19 and December 13, 2021 a strombolian volcanic eruption took place on the island of La Palma. The main edifice was appeared at an altitude of around 900 masl, reaching 1122 masl at the end of the process. The Roque de los Muchachos Observatory (ORM) is an outstanding international astronomical site, hosting some of the most

The emission of very-high-energy (VHE) photons ($E\ \gt\ 100\ \mathrm{GeV}$) in blazars is closely connected to the production of ultra-relativistic particles and the role of these γ-ray sources as cosmic particle accelerators. This work focuses on a selection of 22 γ-ray objects from the 2BIGB catalogue of high-synchrotron-peaked sources, which

We study bulge formation in MW/M31-like galaxies in a Λ-cold dark matter scenario, focusing on the origin of high- and low-Sersic index bulges. For this purpose, we use TNG50, a simulation of the IllustrisTNG project that combines a resolution of ~8 × 10 4 M ⊙ in stellar particles with a cosmological volume 52 cMpc in extent. We parametrize bulge

The v0.8 release of Lightweaver focuses significantly on performance enhancements in the backend, with some improved frontend flexibility regarding the printing of results. If you've been using a v0.8.0rc* version then you will already have most/all of these features. Notable features: Manual SIMD (x86_64) vectorisation throughout the opacity
