Presentamos un estudio arqueoastronómico de dos santuarios rupestres situados en abrigos rocosos, Cueva del Rey Moro y Cueva Negra. Cueva del Rey Moro es un santuario ibérico asociado al poblado de Castellar de Meca. Aunque descartamos resultados anteriores que proponían la orientación del núcleo del santuario hacia el ocaso del solsticio de verano

The paper `A cut-off in the TeV gamma-ray spectrum of the SNR Cassiopeia A' was originally published in 472(3), 2956-2962.

The nature of the Triangulum-Andromeda (TriAnd) system has been debated since the discovery of this distant, low-latitude Milky Way (MW) overdensity more than a decade ago. Explanations for its origin are either as a halo substructure from the disruption of a dwarf galaxy, or a distant extension of the Galactic disk. We test these hypotheses using

Context. The maximum size of the Galactic stellar disk is not yet known. Some studies have suggested an abrupt drop-off of the stellar density of the disk at Galactocentric distances R ≳ 15 kpc, which means that in practice no disk stars or only very few of them should be found beyond this limit. However, stars in the Milky Way plane are detected

Magnetic fields play an important role in many astrophysical processes. They are difficult to detect and characterize since often their properties have to be inferred through interpreting the polarization of the light. Magnetic fields are also challenging to model and understand. Magnetized plasmas behave following highly non-linear differential

By determining the nature of all the Planck compact sources within 808.4 deg2 of large Herschel surveys, we have identified 27 candidate protoclusters of dusty star-forming galaxies (DSFGs) that are at least 3σ overdense in either 250, 350, or 500 μm sources. We find roughly half of all the Planck compact sources are resolved by Herschel into
