... Research . ... There is mounting evidence that AGN feedback is important in galaxy evolution. Radio-mode feedback is thought to be particularly significant because the mechanical action of the expanding lobes provides a strong coupling mechanism between AGN energy and the surrounding environment. In order to quantify this feedback, detailed models of radio lobe evolution are required. ... Cambridge, UK - Nov 2013 . PDF . Poster for Modern Radio Universe conference . ...

... The crucial problem that limits our knowledge of our own galaxy, and prevents us from working out how and when it formed, is our inability to measure direct distances to distant stars, and to determine their proper motions. If we could get accurate parallaxes and proper motions for every star in the galaxy, we'd have things completely wrapped up, and surely we'd be able to figure out galaxy formation. ... Luckily, this is just what should be achievable using space interferometers. ...
