By combining test-particle and self-consistent techniques, we have developed a method to
rapidly explore the parameter space of galactic encounters. Our method, implemented in an …

We present the first results of a study of the morphology, kinematics and ionization structure
of infrared (IR) mergers/quasi-stellar objects (QSOs) with galactic winds. This study is based …

We present an observational study of the interaction effect on the dynamics and morphology
of the minor merger AM 1219− 430. This work is based on r′ and g′ images and long-slit …

We investigate interaction effects on the dynamics and morphology of the galaxy pairs AM
2058-381 and AM 1228-260. This work is based on r′ images and long-slit spectra …

We develop and test an automated technique to model the dynamics of interacting galaxy
pairs. We use Identikit as a tool for modelling and matching the morphology and kinematics …

We studied the spiral pattern in the inner 6 &farcs; 5 (1′′= 257 pc) central regions of the
interacting active nucleus galaxy NGC 1241 using Gemini North Telescope high-resolution …

We present Brγ emission line kinematics of the nuclear region of NGC 253, recently known
to host a strong galactic wind that limits the global star formation of the galaxy. We obtained …

We present photometric and spectroscopic observations of the peculiar object AM 2049−
691, whose most remarkable features are (1) two distinct nuclei connected by a bridge and …

In the last ten years several scenarios have been explored to explain kinematically
decoupled cores (KDCs) in early type galaxies. Among them are large fractions of merging …

We observationally investigate the properties of disk galaxies undergoing minor merger or
capture events. In this context, the properties of two double-nucleus candidate galaxies …
