In this review, we look back upon the literature, which had the GREGOR solar telescope project as its subject including science cases, telescope subsystems, and post-focus instruments. The articles date back to the year 2000, when the initial concepts for a new solar telescope on Tenerife were first presented at scientific meetings. This

La formación estelar es el factor más importante que controla la evolución de las galaxias, con la posible excepción de la interacción galaxia-galaxia, y se ha convertido en uno de los campos más investigados y discutidos en la astronomía actual. Los detalles de la interacción entre el contenido de gas de las galaxias y los procesos que disparan la

El proyecto MASGOMAS (``MAssive Stars in Galactic Obscured MAssive clusterS'') tiene como objetivo descubrir, observar y caracterizar físicamente cúmulos jóvenes, masivos (varios miles de masas solares) y altamente enrojecidos, pertenecientes a nuestra Galaxia, en especial aquellos cuya masa total excede 10000 masas solares. Estos cúmulos, de los

We study for the first time the environment of massive black hole (BH) seeds (˜104-5 M⊙) formed via the direct collapse of pristine gas clouds in massive haloes (≥107 M⊙) at z > 6. Our model is based on the evolution of dark matter haloes within a cosmological N-body simulation, combined with prescriptions for the formation of BH along with both

Context. The VISTA Variable Survey (VVV) is able to map the Galaxy at l ≤ 0° with an unpaired depth (at least 3 mag deeper than 2MASS), opening new possibilities for studying the inner structure of the Milky Way. Aims: In this paper we concentrate on the exploitation of these data to better understand the spatial disposition and distribution of the
