    Red Supergiants as Cosmic Abundance Probes: Massive Star Clusters in M83 and the Mass–Metallicity Relation of Nearby Galaxies
    We present an abundance analysis of seven super star clusters in the disk of M83. The near-infrared spectra of these clusters are dominated by red supergiants...

    Red, redder, reddest: SCUBA-2 imaging of colour-selected Herschel sources
    High-redshift, luminous, dusty star-forming galaxies (DSFGs) constrain the extremity of galaxy formation theories. The most extreme are discovered through...

    Redshift Determination and CO Line Excitation Modeling for the Multiply Lensed Galaxy HLSW-01
    We report on the redshift measurement and CO line excitation of HERMES J105751.1+573027 (HLSW-01), a strongly lensed submillimeter galaxy discovered in Herschel...

    Redshift of southern radio galaxies.
    We report optical spectroscopy and redshift determination for 22 radio galaxies, extracted from the Ekers et al. (1989) compilation. Selected sources, which...

    Rejuvenation triggers nuclear activity in nearby galaxies
    Feedback, in particular from active galactic nuclei (AGNs), is believed to play a crucial role in the evolution of galaxies. In the local Universe, many...

    Relation of internal attenuation, dust emission, and the size of spiral galaxies. Calibration at low-z and how to use it as a cosmological test at high-z
    Aims: Dust in spiral galaxies produces emission in the far-infrared (FIR) and internal absorption in visible wavelengths. However, the relation of the two...
