    A unified model for age-velocity dispersion relations in Local Group galaxies: disentangling ISM turbulence and latent dynamical heating
    We analyse age-velocity dispersion relations (AVRs) from kinematics of individual stars in eight Local Group galaxies ranging in mass from Carina (M* ˜ 106 M⊙)...
  • Publication
    A unified picture of breaks and truncations in spiral galaxies from SDSS and S4G imaging
    The mechanism causing breaks in the radial surface-brightness distribution of spiral galaxies is not yet well known. Despite theoretical efforts, there is not a...

    A Uniform Asteroseismic Analysis of 22 Solar-type Stars Observed by Kepler
    Asteroseismology with the Kepler space telescope is providing not only an improved characterization of exoplanets and their host stars, but also a new window on...

    A Unique Star in the Outer Halo of the Milky Way
    As part of a program to measure abundance ratios in stars beyond 15 kpc from the Galactic center, we have discovered a metal-poor star in the outer halo with a...
  • Publication
    A universal method for solar filament detection from Hα observations using semi-supervised deep learning
    Filaments are omnipresent features in the solar atmosphere. Their location, properties, and time evolution can provide important information about changes in...
  • Publication
    A Variable Mid-infrared Synchrotron Break Associated with the Compact Jet in GX 339-4
    Many X-ray binaries remain undetected in the mid-infrared, a regime where emission from their compact jets is likely to dominate. Here, we report the detection...

    A very cool brown dwarf in UKIDSS DR1
    We report the discovery of a very cool brown dwarf, ULAS J003402.77-005206.7 (ULAS J0034-00), identified in the UKIRT Infrared Deep Sky Survey First Data...
  • Publication
    A very dark stellar system lost in Virgo: kinematics and metallicity of SECCO 1 with MUSE
    We present the results of VLT-MUSE (Very Large Telescope-Multi Unit Spectroscopic Explorer) integral field spectroscopy of SECCO 1, a faint, star-forming...

    A very personal semblance of archaeoastronomy pioneer Professor Michael Hoskin, colleague, mentor and friend
    Michael Hoskin is the name of a scholar whose memory will remain forever linked to cultural astronomy. Professor of History of Science at the University of...
