Kinematic Asymmetries in a Broad Galaxy Sample
نویسندگان
چکیده
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 of the rotation curve is chosen to minimize the asymmetry, then ∼23% of sample galaxies show asymmetry >5% within 1.3re. However, not all gas kinematic asymmetries indicate asymmetries in the underlying potential.

High-resolution Optical Rotation Curves of Low-luminosity Spiral Galaxies
We present optical long-slit spectroscopic observations of 21 low-luminosity, extreme late-type spiral galaxies. Our sample is comprised of Sc–Sm Local Supercluster spirals with moderate-to-low optical surface brightnesses and with luminosities at the low end for spiral disk galaxies (MV 18:8). For each galaxy we have measured high spatial resolution position-velocity (P-V) curves using the H e...
متن کاملKinematic Clues to the Formation and Evolution of Galaxies Kinematic Clues to the Formation and Evolution of Galaxies
To my mother, for her love of science and the curiosity she awakened in me iii iv Abstract This work investigates clues to galaxy evolution in the internal gas and stellar kinematics of 200 nearby galaxies, representing all morphological types and spanning luminosities from M B = ?23 to ?15. The frequency and morphology distribution of galaxies with counterrotating gas and stars provides fossil...
متن کاملKinematically Lopsided Spiral Galaxies
Asymmetries in the distribution of light and neutral hydrogen are often observed in spiral galaxies. Here, attention is drawn to the presence of large-scale asymmetries in their kinematics. Two examples of kinematically lopsided galaxies are presented and discussed. The shape of the rotation curve –rising more steeply on one side of the galaxy than on the other– is the signature of the kinemati...
متن کاملTowards a new classification of early-type galaxies: an integral-field view
In this proceeding we make use of the two-dimensional stellar kinematics of a representative sample of E and S0 galaxies obtained with the SAURON integral-field spectrograph to reveal that early-type galaxies appear in two broad flavours, depending on whether they exhibit clear large-scale rotation or not. We measure the level of rotation via a new parameter (λR) and use it as a basis for a new...
متن کاملA Face–On Tully-Fisher Relation
We construct the first “face-on” Tully-Fisher (TF) relation for 24 galaxies with inclinations between 16◦ and 41◦. The enabling measurements are integralfield, echelle spectroscopy from the WIYN 3.5m telescope, which yield accurate kinematic estimates of disk inclination to ∼ 15◦. Kinematic inclinations are of sufficient accuracy that our measured TF scatter of 0.42 mag is comparable to other s...
