Frequency of Gas-Stellar Counterrotation
S. J. Kannappan, D. G. Fabricant
We search for bulk counterrotation of the gas and stars in 67 galaxies of all types and a wide range of luminosities. Bulk counterrotation characterizes \~25-30% of E/S0's with ext…
Kinematic Asymmetries in a Broad Galaxy Sample
S. J. Kannappan, D. G. Fabricant
We analyze asymmetries in the gas rotation curves of 113 galaxies drawn from the Nearby Field Galaxy Survey, spanning a broad range of luminosities and morphologies. If the origin…
A Broad Search for Counterrotating Gas and Stars: Evidence for Mergers and Accretion
S. J. Kannappan, D. G. Fabricant
We measure the frequency of bulk gas-stellar counterrotation in a sample of 67 galaxies drawn from the Nearby Field Galaxy Survey, a broadly representative survey of the local gala…
Rotation Curve Measurement using Cross-Correlation
Elizabeth J. Barton, Sheila J. Kannappan, Michael J. Kurtz +1
Longslit spectroscopy is entering an era of increased spatial and spectral resolution and increased sample size. Improved instruments reveal complex velocity structure that cannot…
