Galaxies Under the Cosmic Microscope

The red dot on the left panel plot shows Arc #289 on the rest frame B-Band Tully-Fisher relation, compared to high redshift (z = 0.83) field galaxies and other data sets. The inset shows the rotation curve derived from the [OII]3727 line GMOS-IFU observations; horizontal error bars are ~0.7 arcsec, seeing transformed to source frame. The right is the I-band Tully-Fisher relation (with Arc #289 as the red dot) from the references indicated in the panel.
