      Context. Brown dwarfs emit bursts of Hα, white-light flares, and show radio flares and quiescent radio emission. They are suggested to form aurorae, similar to planets in the solar system, but much more energetic. All these ...
    • The evolution of the cold interstellar medium in galaxies following a starburst

(2018-06-05) - Journal article
      We present the dust mass function (DMF) of 15,750 galaxies with redshift z < 0.1, drawn from the overlapping area of the GAMA and H-ATLAS surveys. The DMF is derived using the density corrected Vmax method, where we estimate ...
    • Herschel(star)-ATLAS: properties of dusty massive galaxies at low and high redshifts
