Description
We present an extensive spectroscopic investigation of evolved old- and intermediate-age stellar tracers of the Carina dSph galaxy. We discuss the approach we devised to calibrate the two European Southern Observatory multi-object spectrographs (FLAMES, FORS2). Pros and cons of the two instruments are also mentioned. Finally, we present preliminary results concerning the radial velocity distribution of the entire star sample (˜ 1460 objects).

    JWST and cross-correlation techniques: A faster alternative for atmospheric studies
    The application of cross-correlation techniques to JWST transmission spectra has opened an alternate pathway to study exoplanet atmospheres with JWST observations, which will contribute to pave the road for the first atmospheric studies with ELTs. JWST observed for the first time the hot-Jupiter WASP-39b on July 2022 as part of the JWST Transiting

    The population of barred galaxies in the MACS J0647.8+7015 galaxy cluster at z=0.59
    We study the bar fraction in the MACS J0647.8+7015 cluster of galaxies at z=0.59 using the observations obtained with the NIRCam instrument mounted on the JWST telescope. We visually inspected the near infrared images obtained with the F200W filter of all the cluster members to identify the presence of bars. The cluster member selection was based

    Performance and first measurements of the MAGIC Stellar Intensity Interferometer
    In recent years, a technology developed between the 1950s and 1970s by the pioneering experiments of Hanbury Brown and Twiss has (re)emerged: the Stellar Intensity Interferometry (SII). Unlike amplitude interferometry, SII exploits a second-order effect that can be measured by correlating the light intensities at different detectors without the
