Title: The Cepheid Period-Luminosity Relation (The Leavitt Law) at Mid-Infrared Wavelengths: III. Cepheids in NGC 6822 Authors: Barry F. Madore, Jane Rigby, Wendy L. Freedman, S. E. Persson, Laura Sturch, Violet Mager We present the first application of mid-infrared Period-Luminosity relat...

Cosmology's Best Standard Candles Get Even Better Members of the international Nearby Supernova Factory (SNfactory), a collaboration among the U.S. Department of Energy's Lawrence Berkeley National Laboratory, a consortium of French laboratories, and Yale University, have found a new tech...

Title: A Correction in the Cosmological Parallax--Distance Formula Authors: Ashok K. Singal It is shown that the standard cosmological parallax--distance formula, as found in the literature, including text-books on cosmology, requires a correction. This correction arises from the fact tha...

Astronomers Study Shape of Stellar Candles Astronomers are reporting remarkable new findings that shed light on a decade-long debate about one kind of supernovae, the explosions that mark a star's final demise: does the star die in a slow burn or with a fast bang? From their observations...
