Descripción
Synthetic horizontal branch (HB) stars in globular clusters, when computed on the basis of HB evolutionary tracks and pulsation theory constraints, furnish the best theoretical scenarios for exploration of the age-metallicity relation in globular clusters. Preliminary results are presented from recently computed synthetic models of the horizontal branch. The primary properties predicted for HB stars and RR Lyrae variables are presented and compared with selected observations of variables in the field and in globular clusters.

    NIRPS near-infrared spectrograph: AITV phase at ESO3.6m/La Silla
    NIRPS is a fiber-fed AO nIR spectrograph working simultaneously with HARPS at the La Silla-ESO 3.6m telescope. The cryogenic spectrograph operating at 75K employs a cross-dispersed echelle grating (R4), covering a wavelength range of 0.98-1.80 microns in a single image using a Teledyne Hawaii-4RG infrared detector. In early 2022, the NIRPS

    Transport, handling, and integration of the adaptive optics system for GTC: from the laboratory to the telescope
    The Gran Telescopio de Canarias Adaptive Optics System (GTCAO) is currently in its commissioning phase at Roque de Los Muchachos Observatory (ORM). The GTCAO is a single-conjugated post-focal system equipped with a Shack- Hartmann Wavefront Sensor (WFS) and a Deformable Mirror (DM) conjugated to the pupil, achieving a Strehl Ratio of 65% in the K

    Euclid commissioning results: the near infrared spectrometer and photometer (NISP) signal detection chain
    Euclid, the M2 mission of the ESA's Cosmic Vision 2015-2025 program, aims to explore the Dark Universe by conducting a survey of approximately 14 000 deg 2 and creating a 3D map of the observable Universe of around 1.5 billion galaxies up to redshift z ∼ 2. This mission uses two main cosmological probes: weak gravitational lensing and galaxy
