The Adaptive Optics Lucky Imager (AOLI) is a new instrument designed to combine adaptive optics (AO) and lucky imaging (LI) techniques to deliver high spatial resolution in the visible, about 20 mas, from ground-based telescopes. Here we present details of the integration and verification phases explaining the defiance that we have faced and the

We present a large-scale combination of near-infrared (near-IR) interstellar polarization data from background starlight with polarized emission data at submillimeter wavelengths for the Vela C molecular cloud. The near-IR data consist of more than 6700 detections probing a range of visual extinctions between 2 and 20 {mag} in and around the cloud

Context. Carbon, oxygen and nitrogen (CNO) are key elements in stellar formation and evolution, and their abundances should also have a significant impact on planetary formation and evolution. Aims: We aim to present a detailed spectroscopic analysis of 1110 solar-type stars, 143 of which are known to have planetary companions. We have determined

Accretion of metal-poor gas via cold accretion flows has been recently proposed as a means to trigger/sustain star formation in extremely metal-poor dwarf galaxies (XMPs), a scenario in agreement with theoretical predictions. We report on the tentative detection of CaII absorption used to trace the conditions of the gas clouds in the halo of the

In this contribution we summarise our science preparation activities to complete the CARMENES (http://carmenes.caha.es/) input catalogue of M dwarfs using low-resolution spectroscopy to derive spectral indices sensible to spectral type, gravity and metallicity as well as the level of chromospheric activity. We provide here all this information for

We present a set of six Astronomy outreach workshops for children called ''Chapuzón cósmico''. These workshops took place at the Museo de la Ciencia y el Cosmos of La Laguna (Tenerife, Spain), from autumn 2015 to spring 2016 and reached about 240 children. They were carried out using a very dynamical and participative approach, so as to stimulate
