Experimenting with anaglyphs : NGC 628 hydrogen data




Red-blue 3D glasses required, part two. The hydrogen content of NGC 628. The third axis is velocity, not distance - in reality the gas disc has about the same proportions of a DVD. But it looks more interesting in this view. :)

Experimenting with anaglyphs : the Virgo cluster

The next challenge will be to produce one of an HI data cube, which is quite a lot more complicated. Hence I'm starting early and everything else is on hold (again).

The lonely little smurf

My third paper accepted !

It's about an isolated blue dwarf galaxy. Why the hell didn't I call it AGES VIII : The Lonely Little Smurf ?

I'd thought that the controversy over NGC 1052-DF2 and DF4 was at least partly settled by now, but this paper would have you believe ot...
