    A search for rapid optical spectral variability in blazars
    We report the results of optical monitoring of a sample of AGNs carried out in summer 2002. While rapid optical variability is a well-known aspect of blazar...

    A search for red giant solar-like oscillations in all Kepler data
    The recently published Kepler mission Data Release 25 (DR25) reported on ˜197 000 targets observed during the mission. Despite this, no wide search for red...

    A search for solar g modes in the GOLF data
    With over 5 years of GOLF data having some 90% continuity, a new attempt has been made to search for possible solar g modes. Statistical methods are used, based...

    A search for solar-like oscillations in the stars of M67 with CCD ensemble photometry on a network of 4 M telescopes
    Results are presented from a large observational project directed toward the detection of solar-like oscillations in an ensemble of open cluster stars. Seven...

    A Search for Spectral Hysteresis and Energy-dependent Time Lags from X-Ray and TeV Gamma-Ray Observations of Mrk 421
    Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars...

    A Search for Stellar Populations in High-Velocity Clouds
    We report the results of a photometric search for giant stars associated with the cores of four high-velocity clouds (HVCs)-two of which are compact HVCs-using...

    A search for stellar tidal debris of defunct dwarf galaxies around globular clusters in the inner Galactic halo
    In the hierarchical formation scenario in which the outer halo of the Milky Way is the result of the continuous accretion of low-mass galaxies, a fraction of...

    A search for substellar members in the Praesepe and σ Orionis clusters
    We have conducted deep photometric searches for substellar members of the Praesepe (0.5-1 Gyr) and σ Orionis (3 Myr) star clusters using the Sloan i' and z'...

    A Search for the Optical Counterpart to the Magnetar CXOU J010043.1-721134
    After our tentative detection of an optical counterpart to CXOU J010043.1-721134 from archival Hubble Space Telescope (HST) imaging, we have followed up with...
