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 ...

The Strength of Bisymmetric Modes in SDSS-IV/MaNGA Barred Galaxy Kinematics
The Astrophysical JournalThe Sloan Digital Sky Survey-IV/Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) Survey data provide an unprecedented opportunity to study the internal motions of galaxies and, in particular, represent the largest sample of barred galaxy ...

Elliptical Galaxy Halo Masses from Internal Kinematics
, 2006 The halo masses of nearby individual elliptical galaxies can be estimated by using the kinematics of their stars, planetary nebulae, and globular clusters–ideally in combination.

The Role of Baryonic and Dark Matter in Bar Kinematics
The Astrophysical JournalSimulations predict that bars in galaxies should slow down over time. This is often attributed to the exchange of angular momentum between the bar and other regions of the galaxy, such as the outer disk and dark matter halo, which implies that galaxies ...

A Shocked Wind Interpretation of an Odd Radio Circle
The Astrophysical JournalOdd radio circles (ORCs) are a new class of extragalactic object, with large rings of faint radio continuum emission typically spanning hundreds of kiloparsecs; their origins are unknown.

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]
, 2005 Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

WALLABY Pilot Survey: Characterizing Low-rotation Kinematically Modeled Galaxies
The Astrophysical JournalMany of the tensions in cosmological models of the Universe lie in the low-mass, low-velocity regime. Probing this regime requires a statistically significant sample of galaxies with well-measured kinematics and robustly measured uncertainties.

The Intrinsic Flattening of Galaxy Disks
The Astrophysical JournalHighly inclined (edge-on) disk galaxies offer the unique perspective to constrain their intrinsic flattening, c / a , where c and a are, respectively, the vertical and long radial axes of the disk measured at suitable stellar densities.

The nature and origin of disky elliptical galaxies [PDF]
, 2002 The observational trend that disky elliptical galaxies exhibit younger luminosity- weighted ages than boxy ellipticals is investigated. The presence of a possible young stellar disk embedded in these galaxies is explored by comparing kinematics derived ...
