Investigating the Kinematics of Central and Satellite Galaxies Using Normalizing Flows
The Astrophysical JournalGalaxy clustering contains information on cosmology, galaxy evolution, and the relationship between galaxies and their dark matter hosts. On small scales, the detailed kinematics of galaxies within their host halos determines the galaxy clustering.

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 ...

Constraining dark energy using real and mock galaxy surveys [PDF]
, 2009 In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

Mapping galaxy components with kinematics : dynamical models with stellar and gaseous kinematics [PDF]
, 2021 Mapping galaxy mass distribution is an important means of understanding galaxy morphology and the nature of dark matter haloes, and therefore build up our knowledge of galaxy formation and evolution.

Secondary evolution of galaxies investigated by N-body simulations [PDF]
, 2008 In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

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 ...

The clustering of galaxies in hierarchical galaxy formation models [PDF]
, 2010 Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.

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 ...
