The origin of the empirical laws of galactic scale star formation is considered in view of the
self-similar nature of interstellar gas and the observation that most local clusters are …

Among the various phenomena observed in interacting galaxies is the ejection due to tidal
forces of stellar and gaseous material into the intergalactic medium and its subsequent …

Compact groups of galaxies are unique places where galaxy-galaxy interactions play a
mayor role on the evolution of its members. These strong gravitational encounters can …

Abstract We have obtained Gemini/Gemini Multi-Object Spectrograph spectra of 28 regions
located across the interacting group NGC 6845, spanning from the inner regions of the four …

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 …

Interactions between galaxies are very common. There are special types of interactions that
produce systems called polar ring galaxies (PRGs), composed of a lenticular, elliptical or …

Galaxies-the Milky Way's siblings-offer a surprising variety of forms and colours. Displaying
symmetrical spiral arms, glowing red nebulae or diffuse halos, even the image of a galaxy …

We present the results of Australia Telescope Compact Array (ATCA) H i line and 20-cm
radio continuum observations of the galaxy quartet NGC 6845. The H i emission extends …

We observed the compact group of galaxies NGC 6845 with GMOS-S imaging and long-slit
spectroscopy. The group itself is comprised of two spiral galaxies and two S0 galaxies, and …
