We investigate the abundance of galactic molecular hydrogen (H2) in the `Evolution and Assembly of GaLaxies and their Environments' (EAGLE) cosmological hydrodynamic simulations. We assign H2 masses to gas particles in the simulations in post-processing using two different prescriptions that depend on the local dust-to-gas ratio and the

The spatial variation of physical quantities, such as the mass density, across solar atmospheric waveguides governs the timescales and spatial scales for wave damping and energy dissipation. The direct measurement of the spatial distribution of density, however, is difficult, and indirect seismology inversion methods have been suggested as an

Desde el descubrimiento de los rayos cósmicos (RC) por Victor Hess en 1912, su estudio ha supuesto una forma complementaria a los aceleradores de partículas para buscar nuevas respuestas al modelo estándar de la física de partículas. Esta radiación que incide sobre la Tierra desde el espacio exterior puede revelar indicios de la aniquilación de

Very low-mass stars, brown dwarfs, and giant planets with effective temperatures < 2700 K (or spectral types cooler than M7) are usually referred to as ultra-cool dwarfs. Their low atmospheric temperatures and high pressures favor the appearance of condensates, which may draw together to form cloud-like structures in their atmospheres. According to
