The roiling seas of Triangulum
One more... this time with the colour and height both depending on intensity. The colour scheme has a higher contrast than I'd like, but that's mainly due to the nature of the data and its highly dynamic dynamic range. Still, I like the way a varying landscape emerges from a sea of noise...

The galaxies that quenched backwards
Today's paper is about contrarian galaxies that don't play by the rules. Most galaxies, left to their own devices, build up a big b...

In the last batch of simulations, we dropped a long gas stream into the gravitational potential of a cluster to see if it would get torn...

Of course you can prove a negative. In one sense this can be the easiest thing in the world : your theory predicts something which doesn...

Another day, another paper on how exciting Ultra Diffuse Galaxies are. At first, these large, faint galaxies were just wholly unexpected, a...
Is the video all the same scale? Or is the froth at a smaller scale then when the mountains emerge?
ReplyDeleteThe vertical scale varies from frame to frame, such that the minimum and maximum of each channel reach the same height and depth. That stops the galaxy from becoming absurdly tall, but makes the noise much stronger when there's no source present.
