New blog – finally.

It’s taken me a while to get around to it, but I finally installed wordpress on here.  Not that the old marzipan software wasn’t pretty good, but the ridiculous amount of comment spam it was getting did start causing problems.  So, new blog!

The first post is a quick advert for tonight’s lecture: I’m speaking at Macclesfield Astronomical Society, about how we are now able to map areas the size of the full Moon at milli-arcsecond resolution.  (Now that wont mean a lot to most people so, to put it in context, that’s about 50 times sharper than the Hubble Space Telescope!)  This relatively new technique has opened up the sky to high-resolution surveys at radio frequencies, allowing us to probe nearby galaxies in exquisite detail, and to investigate large populations of much more distant objects.  Right now, this technique generally requires special software, large amounts of disk space, and plenty of processing time, but as computers get ever more powerful and we look towards the Square Kilometre Array with great anticipation, these techniques will become more and more commonplace.  It’s an exciting time to be in radio astronomy.
