    LIGHTS: A robust technique to identify galaxy edges
    The LIGHTS survey is imaging galaxies at a depth and spatial resolution comparable to what the Legacy Survey of Space and Time (LSST) will produce in 10 years...

    Line-of-sight velocity distributions of elliptical galaxies from collisionless mergers
    We analyse the skewness of the line-of-sight velocity distributions in model elliptical galaxies built through collisionless galaxy mergers. We build the models...

    Long-term eclipse timing of white dwarf binaries: an observational hint of a magnetic mechanism at work
    We present a long-term programme for timing the eclipses of white dwarfs in close binaries to measure apparent and/or real variations in their orbital periods...

    Long-term Monitoring, Time Delay, and Microlensing in the Gravitational Lens System Q0142-100
    We present 12 yr of monitoring of the gravitational lens Q0142-100 from the Teide Observatory. The data, taken from 1999 to 2010, comprise 105 observing nights...

    Lower atmosphere and pressure evolution on Pluto from ground-based stellar occultations, 1988-2016
    Context. The tenuous nitrogen (N2) atmosphere on Pluto undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has recently (July...
