The relation between bar formation, galaxy luminosity, and environment
, 2013 We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy luminosities (or, equivalently, stellar masses).

A model for a two component galaxy
, 1978 A simple galactic-structure model is developed in which the galaxy is considered as a two-component-halo-disk structure. The model treats a galaxy as composed of two different axially deformed polytropic structures, homocentrical and coaxial, with ...

The relationship between Gas and Galaxies [PDF]
, 2009 We have investigated the 2D 2-point correlation function, ƐAG, between low column density Lya absorbers and galaxies at a redshift z ~ 1 for the first time.

Integral-Field Spectroscopy of High-Redshift Galaxies: Implications for Early Galaxy Evolution [PDF]
, 2006 Several lines of evidence suggest that the most active phase of galaxy evolution, especially in the most massive systems, was largely completed by $z\sim 1$.

The evolution of dark matter substructure [PDF]
, 2001 This thesis investigates the dynamical evolution of systems orbiting within deeper potentials. Initially we use a simple satellite-halo interaction to study the dynamical processes that act on orbiting systems and we compare these results to analytical ...

The Astrophysical JournalXu & Jing reported a monotonic relationship between the host halo mass M _h and the morphology of massive central galaxies, characterized by the Sérsic index n , at fixed stellar mass, suggesting that morphology could serve as a good secondary proxy for ...

The radio structure of 3C 316, a galaxy with double-peaked narrow optical emission lines
, 2013 The galaxy 3C 316 is the brightest in the radio band among the optically selected candidates exhibiting double-peaked narrow optical emission lines. Observations with the Very Large Array, Multi-Element Remotely Linked Interferometer Network (e-MERLIN ...
