    Time Variation of the Electron Mass in the Early Universe and the Barrow-Magueijo Model
    We put limits on the time variation of the electron mass in the early universe using observational primordial abundances of D, 4He, and 7Li, recent data from...
  • Publication
    Time variation of the fine structure constant in the early universe and the Bekenstein model
    Aims:We calculate the bounds on the variation in the fine structure constant at the time of primordial nucleosynthesis and at the time of neutral hydrogen...

    Time-correlation of the solar p-mode velocity signal from GOLF
    Since the launch of SOHO, the Solar Heliospheric Orbital Observatory, the helioseismic observations are nearly uninterrupted. The GOLF instrument (A. Gabriel et...

    Time-domain Study of the Young Massive Cluster Westerlund 2 with the Hubble Space Telescope. I
    Time-domain studies of pre-main-sequence (PMS) stars have long been used to investigate star properties during their early evolutionary phases and to trace the...

    Time-resolved image polarimetry of TRAPPIST-1 during planetary transits
    We obtained linear polarization photometry (J-band) and low-resolution spectroscopy (ZJ-bands) of TRAPPIST-1, which is a planetary system formed by an M8-type...

    Time-resolved infrared emission from radiation-driven central obscuring structures in active galactic nuclei
    The central engines of Seyfert galaxies are thought to be enshrouded by geometrically thick gas and dust structures. In this paper, we derive observable...

    Time-Resolved Optical Photometry of the Ultracompact Binary 4U 0614+091
    We present a detailed optical study of the ultracompact X-ray binary 4U 0614+091. We have used 63 hr of time-resolved optical photometry taken with three...

    Time-resolved optical spectroscopy of IR GEM in quiescence
    Spectroscopic observations of the dwarf nova IR Gem in the range 4000-7000 A, covering a whole orbital period, are presented. The dates of the observations...

    Time-resolved photometry and spectroscopy of the new deeply-eclipsing SW Sextantis star HS 0728+6738
    We present time-resolved optical spectroscopy and photometry, and far-ultraviolet spectroscopy of HS 0728+6738, a cataclysmic variable discovered in the Hamburg...
