    FIR colours and SEDs of nearby galaxies observed with Herschel
    We present infrared colours (in the 25-500 μm spectral range) and UV to radio continuum spectral energy distributions of a sample of 51 nearby galaxies observed...

    FIR Measurements of Lyα Emitters at z <~ 1.0: Dust Attenuation from PACS-Herschel
    One remaining open question regarding the physical properties of Lyα emitters (LAEs) is their dust content and evolution with redshift. The variety of results...

    First broadband characterization and redshift determination of the VHE blazar MAGIC J2001+439
    Aims: We aim to characterize the broadband emission from 2FGL J2001.1+4352, which has been associated with the unknown-redshift blazar MG4 J200112+4352. Based...

    First detection of the outer edge of an AGN accretion disc: very fast multiband optical variability of NGC 4395 with GTC/HiPERCAM and LT/IO:O
    We present fast (~200 s sampling) $\it ugriz$ photometry of the low -mass AGN NGC 4395 with the Liverpool Telescope, followed by very fast (3 s sampling) u s, g...
