Descripción
Submillimeter observations made with a rapid-scanning interferometer during the solar eclipse of June 30, 1973 are reported. Reduction, correction, and plotting of the data is described, and the obtained results show that the spike can be identified with emission from chromospheric spicules. Models of spicules from optical wavelength data indicate that the spicules are optically thick through the submillimeter range. A more detailed analysis on the number density and length distribution of the spicules above the photosphere, in the region near the chromopause, is pending. It is noted that an examination of large scale brightness distributions across the sun was prevented by time limitations, and that submillimetric limb brightening still remains a mystery.

    Stellar halo density with LAMOST K and M giants

    Aims: We derive the morphology of the stellar component in the outer halo volume, and search for possible overdensities due to substructures therein. Methods: We made use of some of the data releases of the spectroscopic survey LAMOST DR8-DR9 in tandem with distance determinations for two subsamples, that is, of K-giants and M-giants, respectively

    Euclid preparation. XXXVI. Modelling the weak lensing angular power spectrum

    This work considers which higher order modeling effects on the cosmic shear angular power spectra must be taken into account for Euclid. We identified the relevant terms and quantified their individual and cumulative impact on the cosmological parameter inferences from Euclid. We computed the values of these higher order effects using analytic

    The discovery space of ELT-ANDES. Stars and stellar populations

    The ArmazoNes high Dispersion Echelle Spectrograph (ANDES) is the optical and near-infrared high-resolution echelle spectrograph envisioned for the Extremely Large Telescope (ELT). We present a selection of science cases, supported by new calculations and simulations, where ANDES could enable major advances in the fields of stars and stellar
