  • Kinematics of the Tucana Dwarf Galaxy

    We present new FLAMES+GIRAFFE spectroscopy of 36 member stars in the isolated Local Group dwarf spheroidal galaxy Tucana. We measure a systemic velocity for the system of...
  • List of 22 MEGAFLOW fields

    We use the MusE GAs FLOw and Wind (MEGAFLOW) survey to study the kinematics of extended disc-like structures of cold gas around z=~1 star-forming galaxies. The combination of...
  • Morphological study of galaxies in ZwCl0024+1652

    The well-known cluster of galaxies ZwCl0024+1652 at z~0.4 lacks an in-depth morphological classification of its central region. While previous studies provide a visual...
  • Sample of face-on bulgeless galaxies

    We present a list of 220 face-on, almost bulgeless galaxies assumed to be counterparts to the objects from the Reference Flat Galaxy Catalogue (RFGC). We selected the Sc-, Scd-,...
  • The ALMA Calibrator Catalogue

    We present a new catalogue of ALMA observations, the ALMA Calibrator Catalogue (ACC), collecting 3361 bright, compact radio sources, mostly blazars, used as calibrators. These...
  • Classification of emission-line galaxies

    We propose a new soft clustering scheme for classifying galaxies in different activity classes using simultaneously four emission-line ratios: log([NII]/H{alpha}),...
  • HI enhancement in proto-cluster

    In the SSA22 field which exhibits a large-scale proto-cluster at z=3.1, we carried out a spectroscopic survey for Lyman Break Galaxies (LBGs) with the VLT/VIMOS and identified...
  • Molecular gas distribution and star formation

    We study the spatially resolved star formation history (SFH) and molecular gas distribution of 58 nearby galaxies, using integral field spectroscopy from the CALIFA survey and...
  • Oosterhoff dichotomy in Galactic bulge

    We present a study of the Oosterhoff (Oo) dichotomy in the Galactic bulge using 8141 fundamental-mode RR Lyrae stars. We used public photometric data from the Optical...
  • Galaxy-scale lenses in the Kilo-Degree Survey

    We present a new sample of galaxy-scale strong gravitational lens candidates, selected from 904deg^2^ of Data Release 4 of the Kilo-Degree Survey, i.e. the 'Lenses in the...
  • Relative specific Type Ia supernovae rate

    We analyse the 476 SN Ia host galaxies from the All-Sky Automated Survey for Supernova (ASAS-SN) Bright Supernova Catalogues to determine the observed relative Type Ia supernova...
  • UTMOST pulsar timing programme. I.

    We present an overview and the first results from a large-scale pulsar timing programme that is part of the UTMOST project at the refurbished Molonglo Observatory Synthesis...
  • The gas-phase mass-metallicity relation

    We present a detailed exploration of the stellar mass versus gas-phase metallicity relation (MZR) using integral field spectroscopy data obtained from ~1000 galaxies observed by...
  • Proper motions of Milky Way globular clusters

    We use Gaia Data Release 2 to determine the mean proper motions for 150 Milky Way globular clusters (almost the entire known population), with a typical uncertainty of...
  • The ASAS-SN bright supernova catalogue - IV

    In this catalogue we compile information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) as well as all other bright (m_peak_=<17),...
  • Infrared-faint radio sources redshifts

    Infrared-faint radio sources (IFRSs) are an important class of high-redshift active galaxy, and potentially important as a means of discovering more high-redshift radio sources,...
  • Sub-galactic X-ray scaling relations

    We present results from Chandra observations of the X-ray starburst galaxies NGC3310 and NGC2276. We detect 27 discrete sources in NGC3310, and 19 discrete sources in NGC2276...
  • Non-nuclear X-ray sources in nearby galaxies

    We have created a new, clean catalogue of extragalactic non-nuclear X-ray sources by correlating the 3XMM-DR4 data release of the XMM-Newton Serendipitous Source Catalogue with...
  • SNe II as distance indicators at near-IR

    Motivated by the advantages of observing at near-IR wavelengths, we investigate Type II supernovae (SNe II) as distance indicators at those wavelengths through the Photospheric...
  • Diverse galaxy cluster metallicity profiles

    We study a sample of 207 nearby galaxy groups and clusters observed with XMM-Newton. Key aspects of this sample include the large size, the high data quality, and the large...
