Descripción
A new near-infrared camera, SHARP (System for High Angular Resolution Pictures), has been used at the 3.5m ESO NTI' to produce near-diffraction-limited K-band images of the galactic centre region. The new images show a substantial improvement in resolution and sensitivity over previous K-band images. IRS 16 splits into about 20 compact sources, the extended ridge in IRS 16W- E is resolved into at least 5 stellar components, and a faint source (K = 13.7 ± 0.6) is detected at the position of SgrA. Measurement of proper motions of the stellar sources within a few arcseconds of this source will allow us to determine the central mass within the next few years

    The Multi Frequency Instrument 2 (MFI2): mechanical design, manufacture, integration, and commissioning of the MFI2 for the QUIJOTE facility in Tenerife (Canary Islands)
    The QUIJOTE (Q-U-I JOint TEnerife) experiment combines the operation of two radio-telescopes and three instruments working in the microwave bands from 10 to 47 GHz at the Teide Observatory, Tenerife, which has already been presented in previous SPIE meetings. The new Multi Frequency Instrument (MFI2) led by the Instituto de Astrofísica de Canarias

    First light of the upgraded Gregor Infrared Spectrograph
    For more than ten years, the Gregor Infrared Spectrograph (GRIS) has been the infrared spectropolarimeter on the Gregor telescope since its inauguration in 2012. The instrument mainly performs polarimetric observations of the wavelength regions at 1083 and 1565nm, which have high scientific potential. There, observers can find spectral lines that

    Performance of the image persistence model for Euclid infrared detectors
    Large-format infrared detectors are at the heart of major ground and space-based astronomical instruments, and the HgCdTe HxRG is the most widely used. The Near Infrared Spectrometer and Photometer (NISP) of the ESA's Euclid mission launched in July 2023 hosts 16 H2RG detectors in the focal plane. Their performance relies heavily on the effect of
