ASTRO: A pair of "Mice"

Seeing wasn't what I'd have liked but I tried it it anyway. NGC 4676 is
a pair of merging galaxies about 300 million light years away. So they
are pretty small objects. While my image isn't exactly up to Hubble
standards:

I thought I'd try anyway.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Great picture Rick. Colour looks also very good.

Bad seeing or not that's a great image Rick!! This is a difficult pair to
do justice to.

I do a 'galaxy collisions' presentation about twice a year at Kopernik and
I use several neat computer simulations of the collision between these two
galaxies (in addition to others). Several do a good job of predicting the
current appearance of "the mice". One simulation rotates the system 360
degrees and, assuming that it is correct, it shows that the pair is not laid
out flat like you might imagine from an image, but rather have a twisted 3-D
shape.

I assume that from the side that "straight" tail will really be highly
curved like the other one but is straight only due to our perspective.
What's the simulation show?

Rick,

A "simulated movie" is a "picture", so here it is, posted in abpa!
I forget where I got this from......... somewhere "out there" on the web.

Neat.
I got one right for a change.
Need to rotate my shot 90 degrees however.

Sorry for piggybacking: just reporting that George's posting crashes my
newsreader -- hence I can't reply directly. George, any chance of
posting it in an archive that I could download and mess with offline?
