... Research . ... A rare hybrid morphology radio galaxy . ... In this project we will be able to investigate the environmental effect on star formation and galaxy evolution in individual galaxies falling into the cluster through radio observations of active galactic nuclei (AGN). Current models of galaxy evolution regulate the star formation rates within the simulated galaxies by invoking radio-mode feedback from AGN. ... Julie.Banfield@anu.edu.au . ...

... January 8, 2007 . ... SENTINEL CORRESPONDENT . Astronomers at UC Santa Cruz have discovered a surprisingly massive halo of bright, old stars around our galactic neighbor Andromeda, pushing the outer limits of the galaxy to 1.5 million light years, and teaching them how spiral galaxies behave. ...

... Each one is part of the galaxy we live in called the Milky Way. ... Galaxies come in a variety of shapes and sizes; many are spiral disc galaxies, like the Milky Way. ... For many years astronomers have believed that when two similar-sized spiral galaxies collide, they will mash together a type of galaxy called an elliptical galaxy, the shape of a giant squashed football. But, if two spiral galaxies make one elliptical galaxy, how are there still so many spiral galaxies in the Universe? ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
