Descripción
Several aspects of the evolution of an SNR into a low-beta ISM are investigated. The presence of a strong magnetic field in the unperturbed ISM is found to have a profound effect on the structure and evolutionary pattern of an SNR embedded in it. If the field strength is high enough for the outgoing shock to be weak, then most of the explosion energy is taken up by the magnetic configuration, and the initial expansion is rapidly braked. There is no adiabatic Sedov phase. When the interstellar Alfven speed is small compared to the ejecta velocity, the initial phases are similar to the nonmagnetic case, except close to the ejecta where a magnetic sheath may form. A tentative application of this study to different objects in the central regions of galaxies where a strong field is present is suggested.

    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
