I will briefly interrupt my surprisingly busy schedule for a stochastic resumption of AAAAAAAA. Normal services will be resumed at some point in the fullness of time.

EWASS is over and I'm still alive; the 1200-strong horde of barbarous astronomers has been sent back to the hellish netherworld from whence they came. I finally booked my summer holiday to see the total solar eclipse from Grand Teton (hello darkness, bye bye money - also, expedia seems designed to make the whole process as nerve-inducing as watching a horror movie while receiving random electric shocks). My flat has been restored to something approaching normality. Today we have a scientific visitor hanging around after EWASS. Tonight/early tomorrow morning a friend arrives for a week of holiday and on Wednesday I'm giving a 90 minute public talk.

Wheeee.....

A small foray into crowd-sourcing

If you've got a spare 5-10 minutes, why not help me with my research ?

I've got these maps of the hydrogen in a large sample of galaxies, and some of them seem to have streams of gas extending well outside the galaxies themselves. They seem to be lined up in an interesting direction, but I'm worried about confirmation bias - I already know the interesting direction, so I might have unwittingly decided which way the streams are oriented based on that.

The following little quiz lets you decide how you think the streams are oriented. Since there's no other information here apart from the images of the galaxies - nothing to give you any clue as to what the interesting direction actually is - that should remove that bias. More instructions in the link. Enjoy...

I seem to have resumed something approximating a weekly schedule, how about that...

This week : how to stop a rampaging black hole with a few grams of mass, extremely silly old people that make me despair for humanity, and a very special bonus section by way of +Stephen Phillips that demonstrates that not everything is getting worse.
