The Milky Way and the Local Group (MWLG)
  • Publication
    2MASS, SDSS and BVRI photometry for 825 stars (Bilir+, 2008)
    We present colour transformations for the conversion of the 2MASS photometric system to the Johnson-Cousins UBVRI system and further into the SDSS ugriz system...
  • Publication
    3D Asymmetrical motions of the Galactic outer disc with LAMOST K giant stars
    We present a three dimensional velocity analysis of Milky Way disc kinematics using LAMOST K giant stars and the GPS1 proper motion catalogue. We find that...
  • Publication
    3D kinematics through the X-shaped Milky Way bulge
    Context. It has recently been discovered that the Galactic bulge is X-shaped, with the two southern arms of the X both crossing the lines of sight at l = 0 and...
  • Publication
    A 3D view of dwarf galaxies with Gaia and VLT/FLAMES. I. The Sculptor dwarf spheroidal
    We present a new homogeneous survey of VLT/FLAMES LR8 line-of-sight radial velocities (v los) for 1604 resolved red giant branch stars in the Sculptor dwarf...
  • Publication
    A Bayesian estimation of the Milky Way's circular velocity curve using Gaia DR3
    Aims: Our goal is to calculate the circular velocity curve of the Milky Way, along with corresponding uncertainties that quantify various sources of systematic...
  • Publication
    A Blueprint for the Milky Way's Stellar Populations. IV. A String of Pearls-the Galactic Starburst Sequence
    We continue our series of papers on phase-space distributions of stars in the Milky Way based on photometrically derived metallicities and Gaia astrometry, with...
  • Publication
    A calibration point for stellar evolution from massive star asteroseismology
    Massive stars are progenitors of supernovae, neutron stars and black holes. During the hydrogen-core burning phase, their convective cores are the prime drivers...
  • Publication
    A Case against a Significant Detection of Precession in the Galactic Warp
    Recent studies of warp kinematics using Gaia DR2 data have produced detections of warp precession for the first time, which greatly exceeds theoretical...
  • Publication
    A census of massive stars in NGC 346. Stellar parameters and rotational velocities
    Spectroscopy for 247 stars towards the young cluster NGC 346 in the Small Magellanic Cloud has been combined with that for 116 targets from the VLT-FLAMES...
