    A search for planetary nebulae in M33
    We searched for planetary nebulae (PNe) in the nearby spiral galaxy M33 using the Wide Field Camera at the 2.54 m Isaac Newton Telescope of La Palma (Spain)...

    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...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
