    Radial Velocities of Galactic Halo Stars in Virgo
    We present multi-slit radial velocity measurements for 111 stars in the direction of the Virgo Stellar Stream (VSS). The stars were photometrically selected to...

    Radial Velocity of the Phoenix Dwarf Galaxy: Linking Stars and H I Gas
    We present the first radial velocity measurement of the stellar component of the Local Group dwarf galaxy Phoenix, using the FORS1 instrument at the VLT's Unit...

    Radiative transfer models of dusty galaxian discs
    We present a set of face-on models of the radiative transfer of stellar light in exponential discs, taking into account absorption and multiple scattering...

    Radio counterparts of unidentified EGRET gamma-ray sources.
    We present one new radio identification and one confirmation of two high-latitude gamma-ray sources detected by CGRO-EGRET, based on flux density measurements...

    Radio emission during the formation of stellar clusters in M 33
    Aims: We investigate thermal and nonthermal radio emission associated with the early formation and evolution phases of young stellar clusters (YSCs) selected by...

    Radio jets in NGC 4151: where eMERLIN meets HST
    We present high-sensitivity eMERLIN radio images of the Seyfert galaxy NGC 4151 at 1.51 GHz. We compare the new eMERLIN images to those from archival MERLIN...

    Radio Spectra and Star Formation Histories in HII Galaxies
    A sample of actively star forming H II galaxies has been observed in the radio continuum and several optical bands. These galaxies are currently undergoing very...

    Radio spectral properties of star-forming galaxies in the MIGHTEE-COSMOS field and their impact on the far-infrared-radio correlation
    We study the radio spectral properties of 2094 star-forming galaxies (SFGs) by combining our early science data from the MeerKAT International GHz Tiered...

    Radio spectrum evolution and magnetic field in extreme GPS radio sources. The case of RXJ1459+3337
    Aims:The knowledge of the properties of the youngest radio sources is very important in order to trace the earliest phase of the evolution of the radio emission...
