    Dynamical Confirmation of a Black Hole in MAXI J1820+070
    We present time-resolved 10.4 m Gran Telescopio Canarias and 4.2 m William Herschel Telescope intermediate resolution spectroscopy of the X-ray transient MAXI...
  • Publication
    Dynamical confirmation of a stellar mass black hole in the transient X-ray dipping binary MAXI J1305-704
    MAXI J1305-704 has been proposed as a high-inclination candidate black hole X-ray binary in view of its X-ray properties and dipping behaviour during outburst...
  • Publication
    Dynamical Constraints on the Formation of NGC 4472 and Its Globular Clusters
    We present new radial velocities for 87 globular clusters around the elliptical galaxy NGC 4472 and combine these with our previously published data to create a...
  • Publication
    Dynamical constraints on the neutron star mass in EXO 0748-676
    We present Very Large Telescope (VLT) intermediate resolution spectroscopy of UY Vol, the optical counterpart of the low mass X-ray binary (LMXB) X-ray burster...
  • Publication
    Dynamical dark energy in light of the latest observations
    A flat Friedmann-Robertson-Walker universe dominated by a cosmological constant (Λ) and cold dark matter (CDM) has been the working model preferred by...
  • Publication
    Dynamical effects of radiation on the orbits of bodies in the Schwarzschild metric. I
    Dynamical problems associated with the orbital motion of dust particles in strong gravitational and radiation fields are analyzed. The general relativistic...
  • Publication
    Dynamical Evidence for a Black Hole in GX 339-4
    We present outburst spectroscopy of GX 339-4 that may reveal the motion of its elusive companion star. N III lines exhibit sharp emission components moving over...
  • Publication
    Dynamical evidence for a black hole in the X-ray transient QZ VUL (=GS 2000+25)
    We report the first spectroscopic detection of the secondary star in the X-ray transient QZ Vul (=GS 2000+25). Cross-correlation of individual spectra against K...
  • Publication
    Dynamical evolution of globular cluster systems in clusters of galaxies - I. The case of NGC 1404 in the Fornax cluster
    We investigate, via numerical simulations, the tidal stripping and accretion of globular clusters (GCs). In particular, we focus on creating models that...
