Los filamentos y protuberancias solares han sido el foco de muchos estudios desde hace más de 200 años por ser uno de los fenómenos más fascinantes del Sol. Sin embargo, no es hasta ahora, con la instrumentación actual, nuestra potencia de cálculo y una consolidada teoría de generación y transporte de radiación polarizada que podemos estudiar estas

In this work we try to identify if there exist specific patterns in the orientation of Roman towns and military settlements across the Roman Empire, and whether this can be explained by astronomy, as suggested in a number of ancient texts and latter discussed by contemporary scholars. In order to check if cosmology was present in the urban planning

We present ALMA observations of the mid-J 12CO emission from six single-dish selected 870-μm sources in the Extended Chandra Deep Field-South and UKIDSS Ultra-Deep Survey fields. These six single-dish submillimetre sources were selected based on previous ALMA continuum observations, which showed that each comprised a blend of emission from two or

On 2015 September 3, the Chromospheric Lyman-Alpha SpectroPolarimeter (CLASP) successfully measured the linear polarization produced by scattering processes in the hydrogen Lyα line of the solar disk radiation, revealing conspicuous spatial variations in the Q/I and U/I signals. Via the Hanle effect, the line-center Q/I and U/I amplitudes encode

We present the analysis of the planetary microlensing event MOA-2011-BLG-291, which has a mass ratio of q = (3.8 ± 0.7) × 10‑4 and a source star that is redder (or brighter) than the bulge main sequence. This event is located at a low Galactic latitude in the survey area that is currently planned for NASA’s Wide Field Infrared Survey Telescope
