We perform a cross validation of the cluster catalogue selected by the red-sequence Matched-filter Probabilistic Percolation algorithm (redMaPPer) in Dark Energy Survey year 1 (DES-Y1) data by matching it with the Sunyaev-Zel'dovich effect (SZE) selected cluster catalogue from the South Pole Telescope SPT-SZ survey. Of the 1005 redMaPPer selected

High-resolution observations of the Sun reveal the presence of Magnetic Bright Points (MBPs), which are small-scale features associated with strong magnetic field regions, that are found all over the solar photosphere. In this work, we characterize some physical properties and dynamics of MBPs in a quiet Sun region by using time series of images

The TESS mission has reported a wealth of new planetary systems around bright and nearby stars amenable for detailed characterizations of planet properties and atmospheres. However, not all interesting TESS planets orbit around bright host stars. TOI-263 b is a validated ultra-short-period substellar object in a 0.56-day orbit around a faint (V =

En 2018, el ciclo solar 24 entró en una fase de mínimo solar. Durante este periodo, se recogieron 11 millones de datos de brillo cenital del cielo nocturno (NSB, por sus siglas en inglés) en diferentes lugares oscuros del planeta, incluyendo observatorios astronómicos y áreas naturales protegidas, con fotómetros idénticos de banda ancha tipo TESS

El pasado 24 de enero tuvo lugar la puesta en órbita de DRAGO ( Demonstrator for Remote Analysis of Ground Observations), el primer instrumento desarrollado por IACTEC-Espacio. Semanas después llegaban sus primeras imágenes infrarrojas de la Tierra, con una calidad a la altura de las expectativas más optimistas. DRAGO es el resultado de cuatro años

Nuclear star clusters (NSCs) are the densest stellar systems in the Universe and are found in the centres of all types of galaxies. They are thought to form via mergers of star clusters such as ancient globular clusters (GCs) that spiral to the centre as a result of dynamical friction or through in situ star formation directly at the galaxy centre
