    The Photo-Astrometric vertical tracer density of the Milky Way - I. The method
    We introduce a method to infer the vertical distribution of stars in the Milky Way using a Poisson likelihood function, with a view to applying our method to...
  • Publication
    The photo-astrometric vertical tracer density of the Milky Way - II. Results from Gaia
    We use Gaia photometry and astrometry to estimate the vertical spatial structure of the Milky Way at the Solar radius, formally accounting for sample...

    The Physics of Twisted Magnetic Tubes Rising in a Stratified Medium: Two-dimensional Results
    The physics of a twisted magnetic flux tube rising in a stratified medium is studied using a numerical MHD code. The problem considered is fully compressible...

    The PICASSO map-making code: application to a simulation of the QUIJOTE northern sky survey
    Map-making is an important step for the data analysis of cosmic microwave background (CMB) experiments. It consists of converting the data, which are typically...

    The polar orbit of the warm Neptune GJ 436b seen with VLT/ESPRESSO
    GJ 436b might be the prototype of warm Neptunes that have undergone late migration induced by an outer companion. Precise determination of the orbital...

    The population of variable stars in M54 (NGC6715)
    We present new B, V and I CCD time-series photometry for 177 variable stars in a 13 × 13arcmin2 field centred on the globular cluster M54 (lying at the centre...

    The Preparation of the GTC for the Scientific Operation of CanariCam
    CanariCam is a mid-IR camera and spectrograph with coronographic and polarimetric capabilities, built by the University of Florida to operate at the GTC...

    The promise of Bayesian analysis for prominence seismology
    We propose and use Bayesian techniques for the determination of physical parameters in solar prominence plasmas, combining observational and theoretical...

    The puzzling orbital period evolution of the LMXB AX J1745.6-2901
    The orbital period evolution of X-ray binaries provides fundamental clues to understanding mechanisms of angular momentum transfer and loss in these systems. We...
