Description
The bipolar outflow region S 106 is studied with optical spectroscopy and IR mapping techniques. The physical conditions in the ionized region, the density, temperature, ionic and total abundances of the primary atomic species, and the extinction trends and kinematic profiles, are analyzed. A model for the source is proposed in which primary emission is confined to the outer limits of an outflow cavity orientated at an angle of 110 deg to the line of sight. The outflow velocities in the model are shown to be consistent with shock excitation of the lower excitation line species. The IR mapping at J, H, K, L, and M is used to analyze the source NIR energetics and to study trends in surface brightness and color index.

    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

    We used the spectro-photometric information of ∼219 million stars from Gaia's Data Release 3 (DR3) to calculate synthetic, narrowband, metallicity-sensitive CaHK magnitudes that mimic the observations of the Pristine survey, a survey of photometric metallicities of Milky Way stars that has been mapping more than 6500 deg 2 of the northern sky with

    "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
