Cosmic flows: University of Hawaii 2.2-m I-band photometry

Show Summary Details

Preview

Within the ‘Cosmic Flows’ project, I-band photometry of 524 relatively nearby galaxies has been carried out over the course of several years with the University of Hawaii 2.2-m telescope and a camera with a 7.5-arcmin field of view. The primary scientific goal was to provide global magnitudes and inclinations for galaxies for the purpose of measuring distances through the correlation between galaxy luminosities and rotation rates. The 1σ accuracy on a total magnitude is 0.08 mag. The observations typically extend to 7–8 exponential disc scalelengths, so the data are useful for studies of the structural properties of galaxies.
