TOI-836 is a ∼2–3 Gyr K dwarf with an inner super Earth (R = 1.7 R ⊕, P = 3.8 days) and an outer mini-Neptune (R = 2.6 R ⊕, P = 8.6 days). JWST/NIRSpec 2.8–5.2...

Recent success in explaining several properties of the dusty torus around the central engine of active galactic nuclei has been gathered with the assumption of...

Galaxy clusters are being assembled today in the most energetic phase of hierarchical structure formation which manifests itself in powerful shocks that...

Aims. We aim to constrain the amplitude of the linear spectrum of density fluctuations (σ 8), the matter density parameter (Ω m), the Hubble constant (H 0), Γ =...

Clusters of galaxies are the largest known gravitationally bound structures in the Universe, with masses around 1015 M⊙, most of it in the form of dark matter...

This work explores the mixing rate of metals in the interstellar medium (ISM), comparing observational constraints from our solar neighbourhood to high...

Spontaneous breaking of Lorentz symmetry at energies on the order of the Planck energy or lower is predicted by many quantum gravity theories, implying non...

Context. Stellar activity cycles are the manifestation of dynamo process running in the stellar interiors. They have been observed from years to decades thanks...

Internal mixing on the giant branch is an important process which affects the evolution of stars and the chemical evolution of the galaxy. While several...
