Description
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.

    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

    Euclid preparation. XXXVII. Galaxy colour selections with Euclid and ground photometry for cluster weak-lensing analyses

    Aims: We derived galaxy colour selections from Euclid and ground-based photometry, aiming to accurately define background galaxy samples in cluster weak-lensing analyses. These selections have been implemented in the Euclid data analysis pipelines for galaxy clusters. Methods: Given any set of photometric bands, we developed a method for the
