    Kinematical evidence for secular evolution in Spitzer Survey of Stellar Structure in Galaxies (S4G) spirals
    We present a study of the kinematics of a sample of isolated spiral galaxies in the Spitzer Survey of Stellar Structure in Galaxies (S4G). We use Hα Fabry-Perot...

    Kinematical signatures of disc instabilities and secular evolution in the MUSE TIMER Survey
    The MUSE TIMER Survey has obtained high signal and high spatial resolution integral-field spectroscopy data of the inner ~ 6×6 kpc of 21 nearby massive disc...

    Kinematics and stellar population of NGC 4486A
    Context. NGC 4486A is a low-luminosity elliptical galaxy harbouring an edge-on nuclear disk of stars and dust. It is known to host a super-massive black hole...

    Kinematics and stellar populations of the double-barred early-type galaxy NGC357
    We have carried out a kinematical and stellar population analysis of the double-barred galaxy NGC357 to provide a more complete characterization of these...

    Kinematics in the Galactic Bulge with APOGEE. II. High-Order Kinematic Moments and Comparison to Extragalactic Bar Diagnostics
    Much of the inner Milky Way’s (MW) global rotation and velocity dispersion patterns can be reproduced by models of secularly evolved, bar-dominated bulges. More...

    Kinematics of Arp 270: gas flows, nuclear activity and two regimes of star formation
    We have observed the Arp 270 system (NGC 3395 and NGC 3396) in Hα emission using the Galaxy Hα Fabry-Perot spectrometer on the 4.2 m William Herschel Telescope...

    Kinematics of Extremely Metal-poor Galaxies: Evidence for Stellar Feedback
    The extremely metal-poor (XMP) galaxies analyzed in a previous paper have large star-forming regions with a metallicity lower than the rest of the galaxy. Such...

    Kinematics of gas and stars in gas-rich early-type galaxies
    We present gaseous and stellar kinematics for 14 gas-rich early-type galaxies. Half of the galaxies show irregular gaseous velocity profiles, with gas/star...

    Kinematics of globular cluster systems and the formation of early-type galaxies
    We numerically investigate the kinematic properties of globular cluster systems (GCSs) in E/S0 galaxies formed from dissipationless merging of spiral galaxies...
