    Multifrequency studies of galaxies and groups. I. Environmental effect on galaxy stellar mass and morphology
    Context. To understand the role of the environment in galaxy formation, evolution, and present-day properties, it is essential to study the multifrequency...

    Multiline Zeeman signatures through line addition
    Context: To obtain a significant Zeeman signature in the polarised spectra of a magnetic star, we usually “add” the contributions of numerous spectral lines...

    Multiphase characterization of AGN winds in five local type-2 quasars
    We present MEGARA integral field unit (IFU) observations of five local type-2 quasars (QSO2s, z ∼ 0.1) from the Quasar Feedback (QSOFEED) sample. These active...

    Multiphase feedback processes in the Sy2 galaxy NGC 5643
    We study the multiphase feedback processes in the central ∼3 kpc of the barred Seyfert 2 galaxy NGC 5643. We used observations of the cold molecular gas (ALMA...

    Multiple reference star differential imaging with VLT/SPHERE: Influence of the reference frame selection and library
    Context. High-contrast imaging observations mostly rely on angular differential imaging, a successful technique for detecting point-sources, such as planets...

    Multiple stellar populations in Magellanic Cloud clusters. II. Evidence also in the young NGC 1844?
    We used Hubble Space Telescope observations to study the young cluster NGC 1844 in the Large Magellanic Cloud (LMC). We estimated the fraction and the mass...
