What is Jets: Definition and 86 Discussions

The Winnipeg Jets are a professional ice hockey team based in Winnipeg. They compete in the National Hockey League (NHL) as a member of the North Division. The team is owned by True North Sports & Entertainment and plays its home games at Canada Life Centre.
The Jets were established as the Atlanta Thrashers on June 25, 1997, and became the League's 28th franchise when they began play in the 1999–2000 NHL season. True North Sports & Entertainment then bought the team in May 2011 and relocated the franchise from Atlanta to Winnipeg prior to the 2011–12 season (the first NHL franchise to relocate since the Hartford Whalers became the Carolina Hurricanes in 1997). The team was renamed the Jets after Winnipeg's original WHA/NHL team, which relocated after the 1995–96 season to become the Phoenix Coyotes.

    Black Holes emitting jets of gas?

    While watching the Discover Channel, they mentioned a jet of gas emitting from a black hole . . . . yet they say they are so powerful that not even light can escape them. So if not even light can escape the gravity, how would "jets of gas"? As a side note, . . . I realize that most of...

    Energy difference between accelerated particles and Jets

    Hi, In the LHC particles are speed up to 7 TeV, smashing protons into "jets". I asked someone if these jets could also smash up surrounding protons and his answer was no because jets have far less energy. But he couldn't tell the energy difference, so my question is how much energy do these...

    Creating a "Black" Smoke Trail with Model Jets

    I fly model jets that utilize miniature gas turbine engines. If one wishes to introduce a smoke system, A smoke oil tank is installed on board, The smoke oil fluid is then pumped from the tank to a spray nozzle located at the exhaust outlet of the turbine (thrust nozzle). The smoke oil is then...

    Jets from Black Holes - do they carry momentum?

    Q: do jets from Black Holes carry away the momentum from Black holes - in any form? Is matter in these jets rotating? Or may be particles carry the same spin?

    Jets, R-paramater (resolution)

    Hello, I was wondering about this R-parameter that we have in Jet finding algorithms, what is it? How does it change the "physics" when we do jet findings in analysis? Any good introductory material would be really great if I could acquire it :-)

    Hypernova release two huge jets of gamma rays

    I know that a Hypernova release two huge jets of gamma rays, but I'm not real sure on how they are formed. Also it was mentioned that by following the burst of gamma rays, we're looking back in time. How is this actually possible. I have a shaky grasp on the idea.

    Understanding Superluminal Jets and Accretion Emissions from Black Holes

    So I've skimmed certain papers several years ago indicating that radio jets and other accretion-related emissions from black holes can be superluminal. Is this true, or is this just the relative motion of particles in some medium other than vacuum that exceeds the speed of light? I'm...

    Fluid Flow (Water Jets Combine)

    Homework Statement Two water jets collide and form one homogeneous jet as described below: Jet 1, with v=4 m/s, enters directly upwards through a pipe of diameter .10m into a connector pipe. Jet 2, with v= 6 m/s, enters from the left in a pipe of .12m diameter which is perpendicular to Jet...

    Quatum Mechanics Explains Black Hole Jets

    I just had general question about weather or not QM forces a limit on the minimum volume of a BH as well as explains the jets emitted by BH's. It seems obvious that QM would limit the minimum volumn of a BH based on Heisenbergs uncertainty principal. If the volumn were unbounded and could...

    Formation of Relativistic Jets from Black Holes

    I was recently watching a program when "gas" jets, or more properly, plasma jets became a topic. In regards to black holes, I am interested in how such jets can form. I believe that it has something to do with the magnetic fields around a BH, but I am unsure as to how plasma jets form, and...

    Naked Ring Singularities and Jets from AGNs

    At first, I don't see any value in the cosmic censorship hypotesis. If ring singularity (RS) is directly observable (interesting how it looks like. Any simulations?) inside the second horizon, why outside we should be afraid to look at that beast? So I started to thing about RS and Jets...

    Why do smaller holes shoot higher jets of water?

    So I know that F = P*A When you put a nozzle on a hose the area is smaller so does the pressure increase and the force stay the same, does the pressure stay the same and the force increase, or do they both change? Also if you poke a hole in the bottom of a bucket full of water will the...

    Accretion disk/black hole/gas jets

    I have a few questions regarding these phenomena. 1. I don't quite understand what is going on in the picture. Obviously there is a spin on the black hole but why doesn't the gases get sucked straight towards the black hole. I know this is a simulated picture but I don't see how this would...

    Jets speeding up earths rotaion

    I don't know where to put this. But I was thinking about the force of a jet landing (actually stopping using the brakes) Is it possible that if all jets landed the same direction could it slow down or speed up the Earth's rotation after time? Because a jet using thrust to take off I don't...

    W/Z Boson Decays: Quark-Antiquark Pairs to Hadron Jets

    Dominant decays of W/Z bosons are quark aintiquark pairs which decay into jets of hadrons. But how can a quark decay into a hadron? Surely as hadrons are bound states of quarks then hadrons are heavier and so quark->hadrons violates mass conservation (energy conservation). I know I'm...
