    A search for planetary-mass objects and brown dwarfs in the Upper Scorpius association
    We report the results of a deep photometric search for planets and brown dwarfs in the nearby young OB Upper Scorpius association. We obtained optical (I) and...

    A search for planets in the old open cluster NGC 6791
    We describe the results of a search for transit-like events caused by giant planets occulting stars in the old, metal-rich open cluster NGC 6791 based on BVI...

    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 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 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...
