    On the Rapidly Cooling Interior of Supergalactic Winds
    Here we present the steady-state numerical solution and two-dimensional hydrodynamic calculations of supergalactic winds, taking into consideration strong...

    On the Reliability of Microvariability Tests in Quasars
    Microvariations probe the physics and internal structure of quasars. Unpredictability and small flux variations make this phenomenon elusive and difficult to...

    On the use of field RR Lyrae as Galactic probes: VII. Light curve templates in the LSST photometric system
    Context. The Vera C. Rubin Observatory will start operations in 2025. During its first two years, too few visits per target per band will be available, meaning...

    On the Variation of the Peak Asymmetry of Low-l Solar p Modes
    The resonant peaks of solar p modes show small amounts of asymmetry in frequency. Here, we use five independent sets of contemporaneous data, collected over a ~...

    On-sky demonstration of matched filters for wavefront measurements using ELT-scale elongated laser guide stars
    The performance of adaptive optics systems is partially dependent on the algorithms used within the real-time control system to compute wavefront slope...

    Optical and near-infrared observations of the GRB 970616 error box
    We report on near-infrared and optical observations of the GRB 970616 error box and of the X-ray sources discovered by ASCA and ROSAT in the region. No optical...

    Optical properties of Y dwarfs observed with the Gran Telescopio Canarias
    Aims: Our science goals are to characterise the optical properties of Y dwarfs and to study their consistency with theoretical models. Methods: A sample of five...

    Optical spectroscopy of blazars for the Cherenkov Telescope Array - II
    Active galactic nuclei (AGNs) make up about 35 per cent of the more than 250 sources detected in very high-energy (VHE) gamma rays to date with the imaging...

    Optical Spectroscopy of Candidates in the LIGO/Virgo Binary Merger Error Boxes
    We performed optical spectroscopy of the candidates inside the gravitational wave errorboxes (S190408an, S190425z, S190426c, S190510g, S190728q, S190814bv). The...
