    Gemini/GMOS imaging of globular cluster systems in five early-type galaxies
    In this paper, we present deep high-quality photometry of globular cluster systems (GCSs) belonging to five early-type galaxies, covering a range of mass and...

    Gemini/GMOS imaging of globular clusters in the Virgo galaxy NGC 4649 (M60)
    We present Sloan g and i imaging from the Gemini Multi-object Spectrograph (GMOS) instrument on the Gemini North telescope for the globular cluster (GC) system...

    Gemini/GMOS spectra of globular clusters in the Leo group elliptical NGC 3379
    The Leo group elliptical NGC 3379 is one of the few normal elliptical galaxies close enough to make possible observations of resolved stellar populations, deep...

    Gemini/GMOS spectra of globular clusters in the Virgo giant elliptical NGC 4649
    NGC 4649 (M60) is one of a handful of giant Virgo ellipticals. We have obtained Gemini/GMOS (Gemini North Multi-Object Spectrograph) spectra for 38 globular...

    Gemini/GMOS spectroscopy of the spheroid and globular cluster system of NGC 3923
    We present a technique to extract ultra-deep diffuse-light spectra from the standard multi-object spectroscopic observations used to investigate extragalactic...

    Generation of galactic disc warps due to intergalactic accretion flows onto the disc
    A new method is developed to calculate the amplitude of the galactic warps generated by a torque due to external forces. This takes into account that the warp...

    Giant galaxy growing from recycled gas: ALMA maps the circumgalactic molecular medium of the Spiderweb in [C I]
    The circumgalactic medium (CGM) of the massive Spiderweb Galaxy, a conglomerate of merging proto-cluster galaxies at z = 2.2, forms an enriched interface where...

    Giant HVC's and the Rotation Curves of the Milky Way and M31
    We have modelled, for the cases of Milky Way and M31, the effects on the galactic discs, of the arrival at high velocity (≥150 km s-1) of giant HI clouds, with...

    GLACE survey: Galaxy activity in ZwCl0024+1652 cluster from strong optical emission lines
    Although ZwCl0024+1652 galaxy cluster at z ∼ 0.4 has been thoroughly analysed, it lacks a comprehensive study of star formation and nuclear activity of its...
