Descripción
Wide field B,V photometry of the outer regions of the Carina dwarf spheroidal galaxy is presented. Six fields were observed to a distance from the centre up to 4.5 degrees. We detected a sizable sample of faint blue objects, with V> 23 and B-V< 0.4. These objects populate the same region of the color magnitude diagram of the Carina old Main Sequence stars. However, it is not clear whether they are tracing a tidal stream connecting Carina to the Galaxy. We also present some plausible working hypothesis concerning the nature of the objects.

    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
