Descripción
CCD narrow-band H-alpha photometry of the Sextans A Local Group dwarf irregular galaxy is presented. Fourteen H II regions have been recorded. Their identification charts, H-alpha luminosities and sizes are given, and their luminosity and size distributions are discussed. Twenty-five stars with masses between 15 and 30 solar masses, distributed following the IMF of Sextans A, are enough to produce the ionization observed in the galaxy.

    Characterisation at Cryogenic Temperatures of an Attenuator for an Application of Astrophysical Instrumentation with MKIDs
    The use of non-cryogenic certified commercial electronics for cryogenic applications may be attractive due to their cost and availability, but it also carries risks related to reliability, performance and thermal compatibility. The decision to use commercial components that are not certified for cryogenics instead of components specifically

    "SNe Ia Twins for Life": Toward a Precise Determination of H <SUB>0</SUB>
    Here we present an approach to the measurement of extragalactic distances using twin SNe Ia, taken from the early down to the nebular phase. The approach is purely empirical, although we can give a theoretical background on why the method is reliable. By studying those twins in galaxies where peculiar velocities are relatively unimportant, we can

    Euclid: High-precision imaging astrometry and photometry from Early Release Observations: I. Internal kinematics of NGC6397 by combining Euclid and Gaia data
    The instruments at the focus of the Euclid space observatory offer superb, diffraction-limited imaging over an unprecedented (from space) wide field of view of 0.57 deg 2. This exquisite image quality has the potential to produce high-precision astrometry for point sources once the undersampling of Euclid's cameras is taken into account by means of
