  • About ADS | ADS news, blogs, and help pages - NASA ADS
    The importance of ADS’s role in supporting the scientific community has been recognized by societies and individuals If you wish to acknowledge us in a publication, kindly use a phrase such as the following: “This research has made use of the Astrophysics Data System, funded by NASA under Cooperative Agreement 80NSSC21M00561 ”
  • The Gaia mission - ADS - NASA ADS
    Gaia is a cornerstone mission in the science programme of the EuropeanSpace Agency (ESA) The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach Both the spacecraft and the payload were built by European industry The involvement of the scientific community focusses on data processing for which
  • Binding and bonding of commercialization and collaboration . . . - NASA ADS
    Commercialization and collaboration are the essence of the sustainability of applied research These two critical success factors (CSFs) are instrumental in creating a conducive research culture that produces socially impactful innovations and contributes to the country's economic growth
  • SDSS DR7 White Dwarf Catalog - ADS - NASA ADS
    We present a new catalog of spectroscopically confirmed white dwarf stars from the Sloan Digital Sky Survey (SDSS) Data Release 7 spectroscopic catalog We find 20,407 white dwarf spectra, representing 19,712 stars, and provide atmospheric model fits to 14,120 DA and 1011 DB white dwarf spectra from 12,843 and 923 stars, respectively These numbers represent more than a factor of two increase

  • Chaotic Mixer for Microchannels - ADS - NASA ADS
    It is difficult to mix solutions in microchannels Under typical operating conditions, flows in these channels are laminar-the spontaneous fluctuations of velocity that tend to homogenize fluids in turbulent flows are absent, and molecular diffusion across the channels is slow We present a passive method for mixing streams of steady pressure-driven flows in microchannels at low Reynolds

    Lunar electrical conductivity from Apollo 12 magnetometer measurements: Compositional and thermal inferences
  • Planck 2018 results. VI. Cosmological parameters - ADS - NASA ADS
    The Planck base-ΛCDM results are in good agreement with BAO, SNe, and some galaxy lensing observations, but in slight tension with the Dark Energy Survey's combined-probe results including galaxy clustering (which prefers lower fluctuation amplitudes or matter density parameters), and in significant, 3 6σ, tension with local measurements of
  • Fermi Observations of High-Energy Gamma-Ray Emission from GRB 080916C
    Gamma-ray bursts (GRBs) are highly energetic explosions signaling the death of massive stars in distant galaxies The Gamma-ray Burst Monitor and Large Area Telescope onboard the Fermi Observatory together record GRBs over a broad energy range spanning about 7 decades of gamma-ray energy In September 2008, Fermi observed the exceptionally luminous GRB 080916C, with the largest apparent energy
