Kinematics and photometry as complementary tools in the study of barred galaxies
, 2001 Recent advances in observational techniques and theoretical modelling of galaxy kinematics allow us to use more than just optical morphology to discern the structure and dynamics of galaxies.

Simulating supernova feedback in galaxy disks [PDF]
, 2012 In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

, 1989 We model the structure, kinematics, and dynamics of neutral hydrogen gas in galaxies. Our attention is focused on specific features that are commonly observed mainly in the 21-cm line, such as twists, warps and polar rings.

Gemini NIFS survey of feeding and feedback processes in nearby active galaxies : I. Stellar kinematics [PDF]
, 2017 We use the Gemini Near-Infrared Integral Field Spectrograph (NIFS) to map the stellar kinematics of the inner few hundred parsecs of a sample of 16 nearby Seyfert galaxies, at a spatial resolution of tens of parsecs and spectral resolution of 40 kms−1 ...

Shell galaxies: kinematical signature of shells, satellite galaxy disruption and dynamical friction
, 2013 Stellar shells observed in many giant elliptical and lenticular as well as a few spiral and dwarf galaxies presumably result from radial minor mergers of galaxies. We show that the line-of-sight velocity distribution of the shells has a quadruple-peaked shape.

Neutral atomic gas (H I) effectively traces galactic dynamics across mid to large galactocentric radii. However, its limitations in observing small-scale changes within the central few kiloparsecs, coupled with the often observed H I deficit in galactic ...

Distinguishing galaxies as either fast or slow rotators plays a vital role in understanding the processes behind galaxy formation and evolution. Standard techniques, which are based on the λR spin parameter obtained from stellar kinematics ...

Cold gas dynamics of high-z galaxies with ALMA [PDF]
The discovery of galaxies with regularly rotating discs at z > 4 has been a puzzling challenge to galaxy formation models that tend to predict chaotic gas kinematics in the early Universe as a consequence of gas accretion, mergers and efficient ...

Structure and kinematics of early-type galaxies from integral field spectroscopy
, 2016 Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these methods are expensive for large galaxy samples.
