    GAMA/H-ATLAS: the ultraviolet spectral slope and obscuration in galaxies
    We use multiwavelength data from the Galaxy And Mass Assembly (GAMA) and Herschel-ATLAS (H-ATLAS) surveys to compare the relationship between various dust...

    Gamma-ray Excess from a Stacked Sample of High- and Intermediate-frequency Peaked Blazars Observed with the MAGIC Telescope
    Between 2004 and 2009, a sample of 28 X-ray selected high- and intermediate-frequency peaked blazars with an X-ray flux larger than 2 μJy at 1 keV in the...

    Gamma-ray flaring activity of NGC1275 in 2016-2017 measured by MAGIC
    We report on the detection of flaring activity from the Fanaroff-Riley I radio galaxy NGC 1275 in very-high-energy (VHE, E > 100 GeV) gamma rays with the Major...

    Gas accretion from the cosmic web feeding disk galaxies
    Disk galaxies in cosmological numerical simulations grow by accreting gas from the cosmic web. This gas reaches the external disk, and then spirals in dragged...

    Gas accretion from the cosmic web in the local Universe
    Numerical simulations predict that gas accretion from the cosmic web drives star formation in disks galaxies. The process is important in low mass haloes ( 1012...

    Gas Accretion in NGC 3656 (ARP 155)
    We study the gas distribution in the recent merger remnant NGC 3656, a perturbed elliptical. The total gaseous mass content is a few times 10^9^M_sun_. The...

    Gas and dust cooling along the major axis of M 33 (HerM33es). Herschel/PACS [C II] and [O I] observations
    Context. M 33 is a gas rich spiral galaxy of the Local Group. Its vicinity allows us to study its interstellar medium (ISM) on linear scales corresponding to...

    Gas and Dust Emission from the Nuclear Region of the Circinus Galaxy
    Simultaneous modeling of the line and continuum emission from the nuclear region of the Circinus galaxy is presented. Composite models that include the combined...

    Gas and dust properties in the afterglow spectra of GRB 050730
    We present early WHT ISIS optical spectroscopy of the afterglow of gamma-ray burst GRB 050730. The spectrum shows a DLA system with the highest measured...
