What broadens spectral lines?

Comments

vivid green/blue/purple/pink splotches are probably cosmic ray hits that didn't get removed (sorry)

hmmm, this is an AGN according to NED. What's interesting about the greens if you take a ruler, it lines up perfectly...coincidence?

well when I zoom in more it definitely looks like a cosmic ray hit, thought it may have been something special at a high redshift lol

what's a broad-line AGN by the way out a curiousity?

For others reading: cosmic ray strikes can present themselves in a straight line.

Broad line refers to the type of emission lines we see in the spectra. I am sure you have asked this / made reference to this before???

Good to know! I thought they were random. But with this one, when you zoom in you can see a clear lego effect by the galaxy

Not specifically broad-line AGN, I have read about emission line and pea galaxies, but have never seen or read about broad-line AGN's before

We are seeing the black hole nearly edge on, the speed of the swirling gases going towards us and away from us broadens the emission line,

Starting to get the differences in the different types of AGN's lol, doing some reading and it's kinda making sense
