Description
Massive (stellar mass ≥ 1011 M &sun;) galaxies at high redshift (z ≥ 1. 5) remain mysterious objects. Their extremely small sizes (effective radii of 1 - 2 kpc) make them as dense as globular clusters, whereas in the present day Universe similar mass systems are large with old and metal-rich stellar populations. In order to explore this development, we present near-IR IFU observations with SINFONI@VLT for ten massive galaxies at z ˜ 1. 4 solely selected by their high stellar mass which allows us to retrieve velocity dispersions, kinematic maps and dynamical masses. We join this with imaging from the GOODS NICMOS Survey (GNS), which was carried out by our group, and which is the largest sample of massive galaxies (80 objects) at high redshift (1. 7 < z < 3) to date. With these data we show how their morphology changes, possibly as a result of minor merging events also seen in the kinematics.

    Design and manufacture of athermalized optomechanical mounts for GRANCAIN, the infrared imaging instrument for GTC's adaptive optics
    GRANCAIN (GRAN CAmara INfrarroja) is a first-light imaging instrument in the infrared J, H and K bands that will be integrated into the adaptive optics focus of the Gran Telescopio de Canarias. The purpose of the instrument is to capture SWIR diffraction-limited images for a field of view of 22x22 arcsec. The instrument boasts a telecentric optical

    Measuring Rotation Periods and Stellar Oscillations in Red Giants with TESS Data
    TESS is a powerful engine for studying stellar variability. However, it has been challenging to adopt methods used for other space missions, such as Kepler, to infer rotation periods and solar-like oscillation frequencies in TESS data. The availability of multiple sectors of data for most targets, improved stability, and the release of new
