    The dynamical and chemical evolution of dwarf spheroidal galaxies
    We present a large sample of fully self-consistent hydrodynamical Nbody/Tree-SPH simulations of isolated dwarf spheroidal galaxies (dSphs). It has enabled us to...

    The dynamical state of RXCJ1230.7+3439: A multi-substructured merging galaxy cluster
    We analyse the kinematical and dynamical state of the galaxy cluster RXCJ1230.7+3439 (RXCJ1230), at z = 0.332 using 93 new spectroscopic redshifts of galaxies...

    The dynamical status of the cluster of galaxies 1E0657-56
    We present the results of a new spectroscopic and photometric survey of the hot X-ray cluster 1E0657-56, at z=0.296. We determine the presence of a low velocity...

    The dynamical status of the galaxy cluster Abell 115
    Aims:We present the results of a new spectroscopic and photometric survey of the hot, binary X-ray cluster A115 at z = 0.193, containing a radio relic. Methods...

    The early days of the Sculptor dwarf spheroidal galaxy
    We present the high-resolution spectroscopic study of five -3.9 ≤ [Fe/H] ≤ -2.5 stars in the Local Group dwarf spheroidal, Sculptor, thereby doubling the number...

    The EBLM project. II. A very hot, low-mass M dwarf in an eccentric and long-period, eclipsing binary system from the SuperWASP Survey
    In this paper, we derive the fundamental properties of 1SWASPJ011351.29+314909.7 (J0113+31), a metal-poor (-0.40 ± 0.04 dex), eclipsing binary in an eccentric...

    The edge of the M 87 halo and the kinematics of the diffuse light in the Virgo cluster core
    Aims: We study the kinematics and dynamics of the extreme outer halo of M 87, the central galaxy in the Virgo cluster, and its transition to the intracluster...

    The EDGE-CALIFA survey: exploring the role of molecular gas on galaxy star formation quenching
    Understanding how galaxies cease to form stars represents an outstanding challenge for galaxy evolution theories. This process of "star formation quenching" has...

    The edges of galaxies: Tracing the limits of star formation
    The outskirts of galaxies have been studied from multiple perspectives for the past few decades. However, it is still unknown if all galaxies have clear-cut...
