Descripción
We discuss methods and preliminary results in a search for variable stars in the Carina dSph galaxy. This galaxy presents a complex star formation history and hosts a unique sample of variable stars. We collected B,V time series data during different runs, from 1999 to 2004, with the MOSAICII camera available at 4m CTIO telescope. The methodology is based on correlations between a version of the Welch-Stetson variability index, the variability probability of the Lomb-Scargle periodogram, and general statistical parameters associated with the individual light curves.

    NEOMIR: ESA's space-based infrared mission for NEO detection and early warning
    The Near-Earth Object Mission in the Infra-Red (NEOMIR) is the first ESA's space-based mission fully dedicated to discovering near-Earth objects (NEOs), with a focus to detect and raise early warning for the smaller objects that are coming from the Sun direction, thus nearly impossible to be detected by ground-based optical survey. NEOMIR is

    Upgrading the polarisation modulation unit of the Gregor Infrared Spectrograph
    The Gregor Infrared Spectrograph (GRIS) is installed at the Gregor telescope at Observatorio del Teide, Spain. The instrument started observations in 2012 and underwent several upgrades in the following years. Currently, it is experiencing the most significant upgrade so far, which includes, among other things, adding two optical channels to

    Small-ELF Telescope opto-mechanical system: progress on design, manufacturing, and tensegrity prototyping
    Small-ELF (SELF) is a 3.5-meter telescope currently entering the manufacturing phase and will serve as a technology precursor for the much larger telescope named ELF (Exo-Life Finder). The primary objective of the proposed design approach is to to radically improve the system's capabilities for the detection of biomarkers and life in the
