TitleA distance scale from the infrared magnitude/HI velocity-width relation. I. The calibration.
AuthorsAaronson, M.; Mould, J.; Huchra, J.
AbstractThe relation between the infrared H luminosities and the H I velocity widths of extragalactic objects is calibrated in order to serve as an additional distance scale for distant objects. Very large aperture observations of the H magnitudes (1.6 microns) of 12 nearby galaxies are presented, and corrected velocity widths and inclinations for the galaxies are obtained. The slope of the IR/H I relation is taken as -10, a ...
