ggjoy name <--comes from Joy Division's 1979 album cover-- <--comes from pulsar data visualizations!!!!
"It was a complete surprise. In fact, I didn’t know anything about it, and a colleague in the space sciences department, who is now a professor of astronomy at Cornell, Jim Cordes, saw me on the street – he’s been a long time friend – and he said, “oh, by the way, did you know that your image is on the cover of Joy Division?” And, I said no, I had no clue. So I went to the record store and, son of a gun, there it was. So I bought an album, and then there was a poster that I had of it, so I bought one of those too, just for no particular reason, except that it’s my image, and I ought to have a copy of it."
