I don't know about the cosmic wind part, but I was thinking of the expansion of the universe.
What is cosmic wind, anyway?
I knew you meant the expansion of the universe, to which I completely agree which is why I also said (in reference to the "water" quasar) that you can't get there from here, even at the speed of light. My comment was meant more as a joke with your "going against the wind" statement . However, there are plenty of strong sources of energetic turbulence to be found around the universe in the form of solar winds, gamma ray bursts, supernovae, hypernovae, quasar jets, colliding galaxies, and the biggest one of all, the Big Bang.

Hypernovae are probably the most powerful explosions in the universe. According to the ESO, there is a conclusive link between gamma-ray bursts and hypernovae. In effect, my understanding is that hypernovae is basically a supernovae, but on a much larger and more powerful scale from truly gigantic stars, perhaps 10 times more powerful than a supernova. They collapse directly into a black hole and produce powerful plasma jets. Quasars are thought to be caused by supermassive black holes, but both supernovae and hypernovae don't seem to be powerful enough to cause a quasar. I don't think it's really known exactly how supermassive black holes (like those at the center of galaxies) form. You've probably already looked it up, but just in case, here are a few links in reference to hypernovae:

I always liked the theory that supermassive black holes were the result of two or more other black holes merging into one.
That's one thing that could possibly happen, which would really create a strange warpage of space-time around such an event. Simulations show that other interesting things could happen as well when supermassive black holes meet, such as a "recoil effect".
Here are a couple of interesting articles and a video about it.
The water measurement, together with measurements of other molecules in the vapor source, suggests there is enough gas present for the black hole to grow to about six times its already massive size, said Bradford. Whether it will grow to this size is not clear, however, as some of the gas may end up forming stars instead, or be ejected from the quasar host galaxy in an outflow.
I think everyone will find this graphic most interesting There are Moons within our Solar System with 39 times the amount of water here on Earth so it's not as rare in space as was thought in past decades.
I was talking to a couple of guys who were very puzzled about why these gamma rays were being emitted, since they are so rare.
Good link! Perhaps the energy it picks up as it passes through the gas disk? The image shows it produces a faint emission as it approaches the disk, can't be seen when it's behiind it, then shows a strong emission on the way out. The universe is a very strange and remarkable place.

Interestingly, in the more distant past, it was thought that Mars had canals to channel water (even though there are no canals), and there was the idea that Venus was a cloud covered steamy prehistoric jungle. The point being that people thought water existed elsewhere in the solar system. Then from the manned moon missions and the first few views of Mars' cratered, desert-like surface it looked like things were more parched with little to no water (except at the polar ice caps). Now, with much better probes and equipment, water (at least in the form of ice) seems much more abundant again than thought. The thinking seems to have sort of gone full circle.
